Keen Sight and Smell. The snowy owlbear has advantage on Wisdom (Perception) checks that rely on sight or smell.
Incorporeal Movement. The Telthor can move through other creatures and objects as if they were difficult terrain. It takes (1d10) force damage if it ends its turn inside an object.
Spirit Bond. You can add your proficiency bonus to any ability check or saving throw that the Telthor makes.
Unusual Nature. The Telthor doesn’t require air, food, drink, or sleep.
Bound to the Land. A Telthor that moves more than 1 mile from the place or person it guards takes 1 point of damage every minute. This damage ends immediately if it enters its home area again.
Telthor Telepathy. Telthors can communicate with one another telepathically, regardless of language, at a range of 100 feet.
Native Animal Empathy. Telthors can communicate and empathize with animals of their kind. This gives them a +4 bonus on checks to influence the animal’s attitude and allows the communication of simple concepts and, (if the animal is friendly) commands, such as “friend,” “enemy,” “flee,” and “attack.”
