Before attempting to cast a Gut Magic spell, an Ogre Butcher with Tooth-Gnoblars may choose to sacrifice one to get +1 to the total casting value of that Shamanic Victual. Each Tooth-Gnoblar can only be sacrificed once per battle, but a Butcher with two Tooth-Gnoblars may choose to sacrifice both at once for +2 to his casting value if he so wishes.

Note: Tooth-Gnoblars are represented on the character model they accompany; they do not occupy their own bases or have their own characteristics like 'normal' Gnoblars.
