Implant Core [>>>] (manipulate) The taethiagom implants its core into an adjacent section of earth or stone, melding seamlessly and changing its visual appearance to match the surrounding rock. It's immobilized but automatically succeeds at its Deception check to Impersonate the stone around it; creatures actively searching for it can still attempt Perception checks against its Deception DC as normal. A taethiagom can release its implantation as a free action, which has the manipulate trait. A taethiagom's infestation aura and manifold vision are only active while implanted.

Manifold Vision While its core is implanted, the taethiagom can see through the eyes it creates throughout the area of its infestation aura, gaining the benefits of all-around vision.

Infestation Aura (aura, earth, occult) 120 feet. While its core is implanted, a taethiagom infests all earth and stone within 120 feet, as long as there is a contiguous physical connection between the earth, including stone objects touching on the ground. This effect spreads even if the taethiagom does not have line of effect, though it can affect earth or stone on the surface and exposed to the air only if at least part of its core is exposed as well. Within the aura, it can grow maws and eyes everywhere. It can make jaws attacks against any creature, originating from any earth or stone in the aura adjacent to that creature. Determine cover from the origin point of the attack, not from the taethiagom's core.

Speed 20 feet; burrow 20 feet

Melee [>] jaws +29 (magical), Damage 3d12+14 piercing plus barbed maw

Barbed Maw Upon Striking a creature with its jaws, the taethiagom can extend its barbed teeth, immobilizing the target unless it succeeds at a DC 34 Reflex save. While immobilized, the victim takes 3d8 persistent bleed damage and the taethiagom feeds upon its flesh. The creature is immobilized until the taethiagom ends the effect as a free action or the target succeeds at a DC 38 check to Escape. The taethiagom can immobilize any number of creatures with these maws.

Earth Glide The taethiagom can Burrow through dirt and stone at its full burrow Speed, leaving no tunnels or signs of its passing.
