appear to have burst forth from rugged stone.

Spiky Skin (Ex)

An earth yai may
grow spikes from its stony skin at will as a free action. These spikes
are treated as armor spikes that deal 1d10 points of damage.

Stony Missile

As a swift action,
an earth yai can fire an incredibly dense stone from its third eye. This
attack has a range of 200 feet, with no range increment, and deals 3d6
points of bludgeoning damage. Upon striking the target, the stone immediately
makes an Awesome Blow attempt against the target using the earth yai’s

Environment temperate

Organization solitary, band (1 plus 4–8 stone giants), or tribe (1
plus 2–3 stone giant elders and 10–20 stone giants)

Treasure standard

Although they possess the
rocky physiques and near indestructibility of stone giants, earth yai scorn
that race’s humble ambitions, and instead prove as brutal and destructive
as avalanches. For them, physical force and destruction are the ultimate demonstration
of power.

This belief doesn’t
necessarily require them to be the strongest or to go on gory rampages, though.
After all, what is mere strength if a soldier can fire a catapult that brings
down an entire tower, or an emperor can give the decree beginning a war that
ravages an entire empire, using both their tools and words to sow ruin. Such
ability to cause calamity grants one power over others; those who have the potential
to cause the greatest devastation have the greatest power. Earth yai endlessly
seek to hold the greatest power, leading many to become brutal warlords or bandit
kings, but some to embrace more subtle, longterm machinations in their pursuit
of gradual and farreaching ruin.

In its natural form, an
earth yai stands 16 feet tall and weighs 3,000 pounds.


Earth yai possess forms
similar to the rocky bodies of the stone giants their otherworldly shapes mimic.
While stone giants often appear to be sculpted from rock, earth yai tend to
have a more rugged appearance, with features that seem to have been clawed from
mountainsides, teeth and claws like sharp stones, and three eyes like angry
red gems. Their skin is always as hard as rock, the cracks and ravines that
riddle their bodies having no impact on their formidable resilience.

Like their yai brethren,
earth yai possess an unnerving third eye that serves as a portal through which
destruction passes. Whenever one so chooses, it can cause a shard of stone to
blast from its eye at the speed of a catapult shot.

Those struck risk being
crushed by the rock, but might also be thrown aside by the sizable projectile.
Earth yai typically use this incredible ability not only to annihilate those
who oppose them and intimidate witnesses, but also to tear down larger structures
or sow greater devastations, like by using it to start landslides, break dams,
or destroy bridge supports.

& Society

Earth yai dream of conquest
like many other oni, but how they pursue victory tends to vary from individual
to individual. While all would agree that victory is only attained when one’s
foes are crushed and shattered, the methods used to accomplish this goal range
from brute displays of power to the slow erosion of a foe till nothing remains.
The scope of an earth yai’s ambitions also seems largely dependent on its
age, with younger oni proving content to raid territories and subjugate peasant
villages, while older individuals seek greater conquests and the destruction
of whole lands.

Earth yai enjoy the moment
when their long-term plans reach fruition, and might spend decades reveling
in past successes before moving on to new conquests. An earth yai who manages
to conquer a community or subjugate a region might spend this time acting as
a brutal tyrant, installing itself in a palace or fortress and demanding that
its slaves supply its every whim. Those who refuse are dramatically murdered.
While one of these oni would never give up past conquests, most earth yai eventually
grow bored and seek new challenges—if such opportunities don’t present
themselves during the oni’s rule. These oni might move on to find new opponents,
but still regularly return to their past holdings to reinforce their control
and instill dread among their prisoners.

While an earth yai does
not have the greatest Intelligence and cannot necessarily outwit a wise hero,
most possess deep wells of patience and centuries of experience. An oni who
finds itself bested time and time again might wait out foes or opposing alliances.
Their ages of experience mean that earth yai can generally discern the amount
of time they must wait before a threat to them passes—perhaps with the
help of a few inconvenient disasters to accelerate an enemy’s decline.

When two or more earth
yai encounter one another, they invariably engage in an extended strategic match,
seeking to undermine and outdo each other in acts of cleverness and violence.
All earth yai know that a battle between two of their kind must end in a face-to-face
confrontation and brutal combat. Occasions for assassination or impersonal defeats
might arise in such conf licts, but they are never exploited. These oni see
a final battle between members of their kind as a form of honor, and all seek
to avoid slighting even their weakest or most reviled kindred.

Although all earth yai
dream of being the masters of regal citadels dominating lands filled with fearful
servants, few actually achieve this goal. Those still campaigning for their
despotic dreams typically find lairs in mazelike mountain ravines and in large
caverns near the earth’s surface. These hideaways can prove notoriously
difficult to uncover, as the oni often make use of their passwall ability to
sink through solid barriers or walk past gates that don’t appear to be
portals at all. There they meditate and plot, seeing all the threads of probable
events in their minds and determining which ones they need to pull on to shape
the future to their liking. If any creature interrupts an oni in its lair, the
oni violently attacks, viewing intruders as not just dangerous, but dishonorable,
as they trespass upon the oni’s private home. This obsession with privacy
extends not just to yai in their secret lairs, but also to those with greater
holdings. Most earth yai only tolerate creatures of living stone to share their
homes, and only bear the intrusion of lesser creatures when they themselves
demand the lesser creatures’ presence.


Earth Yai Daifu (+1 CR)
Just as stone giants develop a variety of special abilities related to their
age, so too do earth yai grow in power as their years mount upon them. Known
as daifus, such earth yai have Charisma scores of at least 20 and can use the
following spell-like abilities once per day: stoneskin, summon monster XI (earth
elementals only), wall of stone. Most earth yai daifus are sorcerers or oracles
with abilities tied to the earth or destruction. Earth yai daifus add +1 to
their CRs.
