Deactivate the regeneration before applying any damage of a listed type, since that damage might kill the monster by bringing it to Dying 4."

As bizarre in appearance as they are ferocious, thrasfyrs resemble six-limbed bears with bull-like horns, draconic scales, and a fire-breathing serpent for a tail. Every thrasfyr is wrapped in animated chains psychically linked to the creature's mind.
