All siege engines are at least size Large devices and often much larger. Unless stated otherwise in an individual siege engine description, all siege engines use the following rules.

Proficiency: Siege engines are exotic weapons. A creature with the Siege Engineer feat is proficient with all siege engines, including siege firearms. A creature that is proficient in firearms is also proficient in siege firearms, but not other siege engines.

Crew: The sheer size of a siege engine often necessitates a crew for its use. One person of that crew is the crew leader. Usually the crew leader targets or controls the movement of a siege engine; sometimes the crew leader does both. Often the crew leader is required to take actions and make specific checks in order for a siege engine to function. The rest of the crew members are required to spend actions and make checks in order for a siege engine to function.

The number of members in a crew assumes Medium creatures. A ram can be crewed by Small creatures, but it takes double the crew to do the same job. If Large or larger creatures serve as crew members, each Large creature counts as four crew members, a Huge creature counts as eight Medium creatures, a colossal creature counts as 16 Medium creatures, and a gargantuan creature counts as 20 Medium creatures.

Magical and masterwork Siege Engines: Siege engines can be masterwork, increasing their Craft DC by 5 and costing
an additional 300 gp. A masterwork siege engine can be enchanted at twice the cost for a normal magical weapon. The enhancement bonus of a siege engine applies on attack rolls and targeting checks (in the case of indirect ranged siege engines), and in the case of magical siege engines, the enhancement bonus also applies on damage rolls.

Defense and Hit Points: All siege engines are objects. A siege engine has a Dexterity of 0 (-5 penalty) and a further penalty based on its size. Each type of siege engine has its own hardness and hit points. Siege engines can be armored, treat the siege engine as a creature of its size to determine the cost of the armor. masterwork siege engine armor can be enchanted for twice the normal cost to enchant armor. Armored siege engines have an armor bonus equal to that normally granted by the specific armor (shields have no effect on a siege engine), a hardness and hit points equal to that of the armor, and bonus hit points equal to the armor bonus × 5.

Moving Siege Engines: Siege engines have a speed. The speed of a siege engine is the distance it can be moved if its full crew makes a move action to move it. Some siege engines have a speed of 0. If this is the case, the engine must be dissembled before movement is possible, or else mounted on a vehicle. Siege engines that are atop or mounted on vehicles move with those vehicles.

Ranged Attacks: Unlike normal ranged weapons, siege engines do not deal half damage when attacking objects.

Critical Hits: When a direct-fire siege engine or a close assault siege engine scores a critical hit, it confirms the critical and deals critical hit damage just like any other weapon. If an indirect-fire ranged siege engine rolls a natural 20 on its targeting check, it can also score a critical hit. The crew leader must reroll the targeting check to confirm the critical. If the confirmation targeting check is successful, the attack is a critical hit, and the siege engine multiplies its damage by its critical multiplier. Unlike normal attacks, siege engines attacks can deal critical hit damage to objects. Siege engines do not gain the benefit of Critical Feats the crew or the crew leader may have.

Mishaps and Misfires: Rolling a natural 1 on an attack roll or a targeting check made by an indirect-fire ranged siege engine produces a mishap. Usually a mishap applies the broken condition. A non-firearm siege engine with the broken condition takes a -2 penalty on attack rolls, targeting checks, and damage rolls. It also moves at half its normal speed. If the creature that serves as crew leader has the Siege Engineer feat, that creature does not generate a mishap on a natural 1 when firing the siege engine. Firearm siege weapons do not gain a mishap on a natural 1, but instead have a misfire value, like other firearms do. An attack roll or targeting check that falls within the misfire range causes the firearm siege engine to misfire. A misfire always misses, and applies the broken condition to the siege engine firearm. A firearm siege weapon with the broken condition takes all of the penalties and limitations that non-firearm siege engines do, and the misfire range of the firearm siege engine is increased by 4. If the firearm siege engine already has the broken condition when it misfires, it explodes. When a firearm siege engine explodes, it deals its damage to all creatures within a blast range (those within the blast can attempt a DC 20 Reflex save for half damage). The normal misfire range of a firearm siege engine and its blast range are given in the individual firearm siege engine description. Crew leaders with the Siege Engineer feat do not lower the misfire value of firearm siege engines.

Constructing and Repairing Siege Engines: A siege engine is a complex device requiring a DC 20 Craft (siege engine) skill check to build or repair.

Siege Engine Assembly
Engine Size Time Required Workers Required
Small 1 minute 1
Medium 10 minutes 2
Large 1 hour 4
Huge 2 hours 6
Gargantuan 4 hours 8
Colossal 8 hours 12

Disabling Siege Engines: A siege engine is considered a difficult device to disable, requiring 2d4 rounds of effort and a DC 20 Disable Device check to do so. When a siege engine is disabled, it either doesn’t work or is sabotaged and stops working 1d4 minutes after use. Fixing a disabled siege
engine requires a DC 20 Craft (siege engine), Disable Device, or Knowledge
(engineering) check. It takes 10 minutes to fix the device, and the check can be retried if the fix fails.

Assembling Siege Engines: Siege engines are broken down for transport and can be reassembled on the battlefield, requiring the time and number of workers noted below. Each assembly worker must make a DC 10 Craft (siege engine) check; if untrained, they may not take 10. Assembly can be performed with at least half the required number of workers by doubling the time required. If fewer than half are available, the weapon cannot be assembled.

The following are the various entries on the equipment tables for siege engines (given in the column headings on Tables: Ranged Siege Engines and Close Assault Siege Engines). While ranged siege engines use most of these entries, close-assault siege engines only use some of them.

Cost: This value is the siege engine’s cost in gold pieces (gp). The cost includes gear needed to work the engine as well as gear for upkeep. Typical ammunition costs and weights are given in siege weapon description.

Damage: This column gives the damage typically dealt by the engine. If the engine has a special mode of attack or damage, this space is marked by the words ‘see description. If the siege engine does not deal any damage, but rather is a tool for getting close to or over fortifications, this entry features a dash (—). Some ranged siege engines can be loaded with special ammunition that affects or overrides the weapon’s typical damage or range. As large and imprecise weapons, siege engines do not deal sneak attack damage or any other kind of precision damage.

Critical: The entry for this column notes how the engine is used with the rules for critical hits. Unlike normal ranged weapons, siege engines can deal critical damage to objects as well as creatures.

Range: Any attack at more than the distance listed in this entry is penalized for range. Beyond this range, the attack or targeting check takes a cumulative -2 penalty for each full range increment (or fraction thereof ) of distance to the target. Some siege engines have a minimum range for effectiveness. If that is the case, the range of this weapon is followed by a parenthetical with the minimum range, followed by the abbreviation “min.”

Type: Like weapons, siege engines that deal damage are classified according to the type of damage they deal: B for bludgeoning, P for piercing, or S for slashing. Some engines deal damage of multiple types. Some special siege engines (like the firedrake and the firewyrm) deal energy damage, typically fire damage. In those cases, the type of energy damage is listed instead.

Crew: This column gives the number of creatures needed to properly use the siege engine, assuming Medium creatures. Some siege engines can be used with a smaller crew, but there are usually consequences such as slower aiming, firing, or movement.

Aim: This column gives the number of full-round actions (or move actions if the crew leader has the Master Siege Engineer feat) required to aim a siege engine. If the siege engine is being controlled by less than its normal crew complement, the number of actions it takes for the crew to aim the siege engine is doubled.

Load: This column
gives the number of full-round actions (or move actions if the crew leader has
the Master Siege Engineer feat) required to load a siege engine.

 

Speed: This is how
fast the siege engine can be moved with move actions made by its entire crew.

Ranged Siege Engines

 

Ranged siege engines assault
structures and people from a distance, by propelling ammunition in some fashion.
Siege engines hurl massive projectiles in one of two ways: direct fire or indirect
fire. Both take a number of actions to load or aim, and the basic rules are
described below.

 

Load Ammunition:
In order for a ranged siege engine to fire, it needs to be loaded with ammunition.
Loading ammunition takes a number of full-round actions depending on the siege
engine (this time can be reduced to move actions if the crew leader has the
Master Siege Engineer feat.

 

Aiming a Siege Engine:
Ranged siege engines must be aimed in order to attack a desired target (in
the case of direct-fire siege engines) or square (in the case of indirect-fire
siege engines). Aiming takes a number of full-round actions (or move actions
if the crew leader has the Master Siege Engineer feat, with the number depending
on the specific siege engine. Aiming a siege engine with a diminished crew doubles
the amount of time it takes to aim the siege engine. Each time a new target
or square is chosen as the target of a siege engine’s attack, that engine
must be aimed anew.

 

Direct-Fire Ranged Siege
Engines:
Direct-fire weapons launch their projectiles on a relatively flat
trajectory, allowing them to more easily target creatures or pummel barriers
directly in front of them. A direct-fire weapon uses a normal attack roll, with
the normal penalty for nonproficient use. In addition, a direct-fire weapon
takes a –2 attack roll penalty per size category that the weapon is larger
than the creature aiming it. Creatures that have ranks in Knowledge
(engineering) or use a targeting platform (see below) are not adversely affected
by their size when firing direct-fire ranged siege engines. Sheer manpower can
also reduce the penalties for size. Increasing the crew of these weapons by
1 or more can reduce the attack roll penalty for creature size: as long as an
extra crew member is no smaller than three size categories smaller than the
direct-fire weapon, it can reduce the penalty due to the aiming creature’s
size by 2. For example, a Huge ballista fired by a Medium creature that is part
of a crew of two (the creature aiming the ballista and someone to help position
it) takes only a –2 penalty on attack rolls.

 

Indirect-Fire Ranged
Siege Engines:
Indirect-fire weapons launch projectiles in high arcs toward
their targets. They typically lob heavier missiles and payloads than direct-fire
weapons, but they are harder to aim accurately. Indirect weapons can bypass
many forms of fortification, delivering their payloads of solid shot, scatter
shot, or even disease-ridden offal to targets beyond the walls of castles. They
can also be used to batter fortifications where they are most vulnerable, arcing
down on towers and walls, crushing them with the weight of stone or raining
down smaller projectiles on a wall’s defenders. Indirect-fire weapons use
a targeting mechanic similar to that described for catapults, hereafter referred
to as an indirect attack. The following is an update to those rules.

 

Indirect Attack: To
fire an indirect-fire ranged siege engine, the crew leader makes a targeting
check against the DC of the siege engine. This check uses his base attack bonus,
his Intelligence modifier (if
not trained in Knowledge [engineering])
or Knowledge (engineering) skill modifier
(if trained in that skill), any penalty for not being proficient in the siege
engine, and the appropriate modifiers from Table: Indirect Attack Check Modifiers.
If the check succeeds, the ammunition of the indirect attack hits the square
the siege engine was aimed at, dealing the indicated damage or effect to any
object or creature within the area of its attack. Creatures may get a saving
throw to limit the effect of the attack; this is typically based on the type
of ammunition used.

 

If the attack misses the
intended square, roll 1d8 to determine in what direction the shot veers. A roll
of 1 indicates the ammunition falls short (toward the siege engine), with rolls
of 2 through 8 counting squares clockwise around the target square. Roll 1d4
for every range increment at which the attack was made (1d4 if the target square
is within the engine’s first range increment, 2d4 if the target square
is within the second range increment, and so on). The total is the number of
squares by which the attack misses, with the direction in which the squares
are counted determined by the d8 roll. The ammunition deals its damage and any
other effects in the square it lands on.

Special
Siege Engine Ammunition

 

The following kinds of
ammunition can be used either in select types of indirect-fire siege engines,
or with cannons. The ammunition description specifies which types of siege engines
use the special ammunition. The costs and weights on Table: Special Siege Engine
Ammunition are for individual uses of special ammunition.

 

 


Special Siege Engine Ammunition
Ammunition Cost Weight
Alchemical fire 200 gp 10 lbs.
Blast shot 30 gp 25 lbs.
Bomb 600 gp 30 lbs.
Chain shot 50 gp 30 lbs.
Liquid ice 400 gp 20 lbs.
Plague bundle 80 gp 20 lbs.
Smoke shot 250 gp 20 lbs.

Alchemical Fire: This
hard, ceramic canister of alchemist’s fire can be used as ammunition in
catapults and trebuchets. When it hits its target square, it deals 4d6 points
of fire damage to each creature and wooden structure within 5 feet of the target
space, and each creature must make a DC 20 Reflex saving throw or catch on fire
(wooden objects automatically catch on fire). Every creature and wooden object
within the area between 5 and 30 feet of the target space must make a DC 20
Reflex saving throw or take half the fire damage, but they do not catch on fire.
On a siege engine mishap, this ammunition explodes before it is launched, dealing
its damage to the siege engine and all nearby creatures and wooden objects as
if one of the spaces of the siege engine (crew leader’s choice) were the
target square. This alchemical fire ignores the hardness of wooden objects.

 

Blast Shot: Instead
of a single hard ball, this ammunition is a bundle of large pellets, balls,
or pieces of scrap metal, propelled a short distance by black
powder
and attacking
all creatures and objects within an area. Both cannons and fiend’s mouth
cannons can fire this kind of ammunition. When such a siege engine fires this
ammunition, it hits every creature and object within a 30-foot-cone burst. The
siege engine makes attack rolls against each creature and unattended object
in the burst. It must miss every creature or target to misfire, and a misfire
generates the normal effect. It deals its normal damage on a hit, but does not
ignore the hardness of objects.

 

Bomb: A bomb is
a metal canister filled with metal balls and black
powder
that can be used as
ammunition in catapults and trebuchets or carried by two Medium creatures or
one Large creature to its destination. A bomb either explodes on impact (if
fired from a catapult or trebuchet, or within 3 rounds of a fuse being lit if
carried). When it explodes, it deals 6d6 points of piercing and bludgeoning
damage to all creatures and objects within 30 feet of the target square. On
a siege engine mishap, this ammunition explodes before it is launched, dealing
its damage to the siege engine and all nearby creatures and wooden objects as
if one of the spaces of the siege engine (crew leader’s choice) were the
target square. It ignores the hardness of wood and stone.

 

Chain Shot: This
siege engine firearm ammunition can be loaded in a cannon or a fiend’s
mouth cannon. It is especially good at tearing through sails and dirigibles
(see Vehicles), dealing double its normal damage to those forms of propulsion.
When fired at a creature, on a hit, the creature must succeed at a DC 20 Fortitude
saving throw or be knocked prone.

 

Liquid Ice: This
hard, ceramic canister filled with alchemical liquid ice can be used as ammunition
in catapults and trebuchets. When it hits its target square, it deals 4d6 points
of cold damage to each creature within 5 feet of the targeting space, and each
creature must make a DC 20 Fortitude save or become entangled for 1 round. Every
creature within the area between 5 and 30 feet of the target space must make
a DC 20 Fortitude saving throw or take half damage. On a siege engine mishap,
this ammunition explodes before it is launched, dealing its damage to all nearby
creatures as if one of the spaces of the siege engine (crew leader’s choice)
were the target square.

 

Plague Bundle: This
hard, ceramic canister is filled with a noxious mass of diseased carrion and
offal that can be used as ammunition for a catapult or a trebuchet. It deals
only half damage, but every creature hit by it is exposed to filth
fever.
A GM might allow a plague bundle to inflict other diseases.

 

Smoke Shot: This
hard ceramic sphere contains two alchemical substances separated by a thin barrier,
much like a smoke pellet in larger form. When it hits the targeting space, it
deals 2d6 points of damage to any creature in that space, and the substances
mingle and then create an area of foul but harmless yellow smoke radiating 30
feet from the target square. Treat the effect as a fog cloud spell. On a siege
engine mishap, the ammunition explodes before it is launched. Its effect is
centered on one of the spaces of the siege engine (crew leader’s choice).

 

Close
Assault Siege Engines

 

While most siege engines
attack at range, some are used up close to directly undermine defenses, batter
through them, or otherwise bypass them. Some close assault weapons are not even
weapons at all, but instead provide means for assault forces to protect themselves
or circumvent fortifications without destroying them.

Structure
Hardness and hit points

 

While armies can use siege
weapons against troops, usually the goal of a siege engine is to demoralize
foes and pound their structures to rubble. The following rules give the statistics
for various buildings and barriers that are often the targets of siege engine
attacks. They are split up into three different categories: buildings, gates,
and walls.

 

When any of these structures
gain the broken condition, their hardness is halved, along with any other effects
of the broken condition.

Buildings

 

Buildings are sizable structures
with many hit points and very poor ACs (a Large building is AC 4, a Huge building
is AC 3, and a Gargantuan or larger building is AC 0). When a building is reduced
to half its hit points, it is broken—it still stands, but only partially.
It can be easily entered, and for all intents and purposes it has been breached.
Reducing a building to 0 hit points completely destroys that building. Creatures
inside the building suffer the effects of a cave-in.

 

All these building statistics
assume that the structure’s inside is somewhat hollow but sturdily built,
with enough space for its occupants to walk around inside. Flimsy buildings
have half the hit points of the buildings detailed in Table: Buildings. Buildings
can be magically treated, like dungeon walls and doors can. Doing so doubles
their hardness and hit points. Magically treating a building costs 5,000 gp
for a Large building, 10,000 gp for a Huge building, 20,000 gp for a Gargantuan
building, and 40,000 gp for a Colossal building. A spellcaster with the Craft
Magic Arms and Armor
feat can magically treat buildings.

 

For larger buildings, put
together multiple buildings of these sizes and add the hit points together.

Gates serve as the entrances
and exits to fortified structures, and are typically the weakest spots in any
fortification’s defenses. Gates are at least Large, but can be as large
as Colossal. It typically takes three full-round actions to open or close a
Large gate (up to three creatures can work together to close a Large gate as
a full-round action), and larger gates typically take at least a minute to close
or open. Gates have ACs based on their size (a Large gate is AC 4, a Huge gate
is AC 3, and a Gargantuan or larger gate is AC 0).

 

Gates can be magically
treated. Doing so doubles the hardness and hit points. Magically treating a
gate costs 2,000 gp for a Large gate, 4,000 gp for a Huge gate, 8,000 gp for
a Gargantuan gate, and 16,000 gp for a Colossal gate. A spellcaster with the
Craft Magic Arms and
Armor
feat can magically treat gates.

 

Gates can be attacked and
damaged, or they can become broken (as the condition) with a successful Strength
check, usually as a result of ramming. When a gate gains the broken condition,
it is effectively breached, and can be moved through as if it were an opening
one size smaller.

Walls

Regensburger Schiffslände, Aquarell, 28 x 23 cm Date 1872 Anonymous

The walls that guard castles and cities are sturdy fortifications, usually constructed in a series of 5-foot squares. A square of wall has an AC of 5, and hardness and hit points equal to its type.

Squares of walls can be magically treated. Doing so doubles the hardness and hit points. Magically treating
wall squares costs 500 gp per wall square. A spellcaster with the Craft
Magic Arms and Armor
feat can magically treat walls.

 

When a wall gains the broken
condition, its hardness is halved, but the wall is not breached. Only destroying
a section of wall allows it to become breached. When a square of wall is breached,
any sections directly above it fall onto the missing section of walls. Doing
this reduces the falling wall section to half its current hit point total –1,
which applies the broken condition to that square of wall.
