Vastwood Hydra by Slawomir Maniak

Hold Breath. The hydra can hold its breath for 1 hour.   Multiple Heads. The hydra has five heads. While it has more than one head, the hydra has advantage on saving throws against being blinded, charmed, deafened, frightened, stunned, and knocked unconscious. Whenever the hydra takes 25 or more damage in a single turn, one of its heads dies. If all its heads die, the hydra dies.   At the end of its turn, it grows two heads for each of its heads that died since its last turn, unless it has taken fire damage since its last turn. The hydra regains 10 hit points for each head regrown in this way. Reactive Heads.   For each head the hydra has beyond one, it gets an extra reaction that can be used only for opportunity attacks.   Wakeful. While the hydra sleeps, at least one of its heads is awake.

Actions

Multiattack. The hydra makes as many bite attacks as it has heads.   Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 10 (1d10 + 5) 1d10+5 piercing damage.

The hydra is a reptilian horror with a crocodilian body and multiple heads on long, serpentine necks. Although its heads can be severed, the hydra magically regrows them in short order. A typical specimen has five heads.   Hardy Water Dwellers. Hydras are natural swimmers, dwelling in rivers, along lakeshores, in ocean shallows, and in wetland bogs. A hydra rarely requires shelter from the elements, so it doesn't normally have a lair. Only in colder climes are hydras drawn to the protection of sheltered caverns and ruins. When a hydra sleeps, at least one of its heads remains awake and alert, making the creature difficult to catch by surprise.
