Freeze (Ex) Dembomor can pretend to be immobile tree stump in fitting environment taking 20 on a Stealth check.
Hidden Heart (Ex) Dembomor gains +20 bonus to Bluff checks made to hide his feelings toward others. Being an animated tree with no face expression and wooden voice helps hide emotions well.
Nature Magic (Sp) Dembomor uses Wisdom bonus to determine concentration checks and saving throw DC of his spell-like abilities.
Dembomor heart is rotting with hatred he feels toward the mortal (and some immortal) races. He secretly detests humanoids, and much less secretly, abhors monstrous humanoids and dragons, he wishes for their total eradication and hopes to use their remains as fertilizer. He is no fool, though, and he hides his feelings well—he only directly attacks humanoids when they can't escape and expose his homicidal hatred. When the odds are not in his favor, he tries to subtly lead humanoids into danger—providing them with inaccurate directions, sending them into lethal dungeons, hiring them to fight dragons or other humanoids...
