Tales of Tolgard
A stone wolf appears as a wolf carved out of a solid block of stone. No two stone wolves look the same, though they all have white-hot fire opals for eyes. Stone wolves are five to six feet in length.
A stone wolf’s preferred tactic is to lie silently and unmoving, pretending to be a statue, and attack enemies with surprise. Stone wolves always hear the call of their creator, and return to him immediately if he calls. As a construct, stone wolves are immune to mind-influencing effects, poison, disease, and similar effects.
The stone form of a stone wolf causes certain spells to affect it in unexpected ways. Stone to Flesh causes the stone wolf to become a normal wolf. Transmute Rock to Mud destroys it instantly, turning into a pile of mush.
