Regeneration: Bendy regains 20 hit points at the start of each of his turns unless he has taken damage from water (see below).

Water Weakness: For every gallon of water that touches Bendy, he takes 1 acid damage. If he starts his turn in at least 1 foot of still water (such as a pool or lake), he takes 5 acid damage; if he starts his turn in at least 1 foot of running water (such as a river or ocean), He takes 20 acid damage. any acid damage he takes in this way is magical damage for the purpose of overcoming his resistance (normal form) or immunity (Beast form)

Multiattack: Bendy makes 4 Claw attacks or 6 when he's in Beast Mode. He also uses Inky Teleport if it's available.

Bite: Melee Weapon Attack: +16 to hit, reach 5 ft., 1 target. Hit: 23 (4d6 + 9) piercing damage or 37 (8d6 + 9) in Beast Mode plus 10 (1d20) poison damage.

Beast Mode: If Bendy takes damage to reduce him to 100 hit points or less, he transforms into a beast. He becomes Large, gains Immunity to all non-magical damage and resistance to any other damage, and does more damage (see attacks). These effects stay until he finishes a long rest, even if his regeneration restores him to over 100 hit points.
