Clockroot Treant

An ancient tree whose roots have grown down through buried clocks, old calendars, and moments that refused to pass. It moves with the slow inevitability of something that has all the time there is. Its roots slam the ground and the air thickens with stolen hours, leaving you staggering a beat behind everyone else.

Root Slam: bludgeoning, 15 ft, +6 to hit, 3d8+5. Stolen Hour: 20-ft radius, save Con Tough or slowed/staggered as the creature loses a few heartbeats, cooldown 3 rounds.

Chronal Bark: immune to aging effects and resistant to piercing/slashing. Fire damages it normally, but each fire hit accelerates its next attack by +1. Senses: Vibration Sense (feels movement, 90 ft), Dark Sense (30 ft).
