Gegnir

A nine-headed jotund troll of monstrous size, Gegnir is a hydra-like terror whose every severed head writhes back into place. Cut one away and two more snap and snarl in its place, each set of jaws hungry for a new victim.

Gegnir has all-around vision and regeneration 40 (deactivated by acid or fire).

Head Regrowth Gegnir has nine heads, and he can use regeneration to regrow a head that is severed from an effect like a vorpal weapon. After regaining Hit Points from regeneration, the jotund troll attempts a DC 8 flat check. On a success, one missing head is fully restored; on a critical success, two missing heads are fully restored. If Gegnir loses his last remaining head, he dies immediately.

Multiple Opportunities A jotund troll gains an extra reaction per round for each of their heads beyond the first, which they can use only to make Attacks of Opportunity with their jaws or to Fast Swallow.
