Blackwater Leviathan Young

A young leviathan risen from black, lightless water, already big enough to mistake a fishing boat for a meal. It hunts unseen below the surface, a shape you feel in the swell before you ever see it. It surges up in a drowning wave that drags the unready under, then takes them in the dark, where its eyes work and yours do not.

Blackwater Bite: piercing, melee/15 ft, +7 to hit, 3d10+6. Drowning Wake: 40-ft cone/wave, save Con Tough or 3d8 and pulled underwater/prone, cooldown 3 rounds.

Abyssal Swimmer: breathes water/air, invisible in black water beyond 15 ft. Vulnerable to lightning while submerged. Senses: Night Vision (90 ft), Vibration Sense (feels movement, water vibration, 60 ft).
