  • Bite. Melee Weapon Attack: +22 to hit, reach 20 ft., one target. Hit: 51 (6d12+12) piercing damage. If the target is a creature, it is grappled (escape DC 28). Until this grapple ends, the target is restrained.

There is no greater alpha predator than the world wolf fated to bring apocalyptic ruin in his wake: Fenrir.

Chained and imprisoned by the gods, when the deific lupine eventually breaks free from his bonds it’s said that nothing will be able to stop his rampage. After time immemorial unable to hunt, when he knows freedom again Fenrir relishes it and eats voraciously, consuming every thing of flesh that his godly snout can sniff out-taking particular delight in the crunchy offerings presented by armored platoons of soldiers. If allowed to eat his fill the world wolf rests but only for a few hours before he awakens to feast anew.
