Crysmals

Outsider: An outsider is at least partially composed of the essence (but not necessarily the material) of some plane other than the Material Plane.

Outsiders have darkvision.

Unlike most living creatures, an outsider does not have a dual nature — its soul and body form one unit. When an outsider is slain, no soul is set loose. Spells that restore souls to their bodies, such as raise dead, reincarnate, and resurrection, don’t work on an outsider. A different magical effect, such as limited wish, wish, miracle, or true resurrection, is required to restore it to life. A native outsider can be raised, reincarnated, or resurrected just as other living creatures can be.

Outsiders breathe, but do not need to eat or sleep (although they can do so if they wish). Native outsiders breathe, eat, and sleep.

Earth: Earth creatures are outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock. Earth creatures with a burrow speed possess tremorsense.

Elemental: An elemental is a being composed entirely from one of the four classical elements: air, earth, fire, or water.

They have immunity to bleed, paralysis, poison, sleep effects, and stunning.

They are not subject to critical hits or flanking. They do not take additional damage from precision-based attacks, such as sneak attack.

Elementals do not breathe, eat, or sleep.

Scorpion-like crysmals originate in the deepest caverns of the Plane of Earth. On rare occasions, these strange creatures wind up on the Material Plane, usually in subterranean areas rich with natural gem and crystal formations. The crystalline planes of their bodies absorb and refract natural light, which some claim is the source of their supernatural powers.

They have spell-like abilities.

Once per day, a crysmal can launch its tail spike as a ranged attack that shatters when it hits, dealing piercing damage to the target and to all creatures in adjacent squares. The spike regrows in a day, but until it does, its impaired sting does less damage.

Singular in purpose, a crysmal seeks only to reproduce. It does so by gathering stone crystals and gemstones, fashioning them into a Tiny facsimile of its own body, and jolting the new creature to life with a burst of the crysmal’s own life energy. These newly created crysmals are known as shardlings, and grow to adulthood after a few months of gorging on crystals and gemstones.

They have damage reduction overcome by bludgeoning weapons.

They are immune to cold and fire.
