Vanward Sentinel of Stone and Storm

Titanic Resilience

If the Sentinel takes 50 or less damage from a single source, it takes no damage instead. (Recharge 5-6)

While not incapacitated, the Sentinel emits a 30 ft. aura of crushing stone pressure and debris.

• Enemies starting their turn in the aura take 10 (3d6) Bludgeoning damage.

• Movement within the aura costs 2 extra feet per 1 foot moved (cumulative with difficult terrain).

• Creatures that end their turn in the aura must succeed on a DC 20 Constitution save or gain 1 level of Exhaustion (this exhaustion fades after a short rest).

Avalanche Heart

When reduced to 0 hit points, the Sentinel crumbles in a violent collapse of stone and pressure:

• 60 ft. radius burst.

• All creatures must make a DC 20 Strength Save or take 10d10 Bludgeoning Damage and be knocked prone. Half damage on a success.
