Urglid

Tremorsense (Imprecise) 60 feet — Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.

Telepathy 100 feet (aura, magical, mental) — A monster with telepathy can communicate mentally with any creatures within the listed radius, as long as they share a language. This doesn't give any special access to their thoughts, and communicates no more information than normal speech would.

Consecration Vulnerability — Dedicated to the desecration of graves, an urglid takes 3d6+6 mental damage each round they're within the area of an effect with the consecration trait. In addition, the demon's weakness to holy increases to 30 for 1 round the first time they take damage from Holy Water each turn.

Constant Spells — A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

+1 Status to All Saves vs. Magic —

Earth Glide — The urglid can Burrow through any earthen matter, including rock. When they do so, the urglid moves at their full burrow Speed, leaving no tunnels or signs of its passing unless they choose to do so.

Gravechoke (concentrate, divine, earth, olfactory) — The urglid emits a putrid pulse that targets all living creatures within a 30-foot emanation. Creatures in this area that fail a DC 30 Fortitude save become Sickened 1 (Sickened 2 on a critical failure).

Ravenous Earthunholy (concentrate, earth) — With a single, devious thought, the urglid causes a mound of grave soil to well up at a creature's feet. That creature must succeed at a DC 30 Reflex save or become Restrained (Escape). The restrained creature then begins sinking below the ground into a spontaneously formed grave. A creature restrained by this ability for 3 rounds is buried 6 feet deep in the ground and begins suffocating within 1 minute. A buried creature must be dug up to be freed (see Burial on page 96 of GM Core). A creature that is slain by Ravenous Earth rises as a Ghoul the next midnight.
