Attack of Opportunity [R]

Botanic Interruption [R] (evocation, primal) Trigger The taiga yai is standing in natural foliage or undergrowth and is targeted by a melee attack; Effect The taiga yai infuses their power within the plants around them, causing the plants to shoot up and create a protective barrier. The taiga yai gains a +2 circumstance bonus to AC against the triggering attack roll. If the attack misses, the attacker must attempt a DC 33 Reflex save. On a failed save, the attacker is immobilized for 1 round as the plants grab hold of them; on a critical failure, the attacker is also knocked prone.

Change Shape [>] (concentrate, polymorph, primal, transmutation) The taiga yai takes on the appearance of a taiga giant. This doesn't change their Speed or Strike attack and damage.

Return to Nature [>] (earth, manipulate) The taiga yai commands underground plant roots to drag a creature within 60 feet into the earth. The target must succeed at a DC 35 Fortitude save or be immobilized for 1d4 rounds. After this time, the creature is buried; it is grabbed, begins to suffocate, and takes 4d6 bludgeoning damage each round they remain buried. To escape either while immobilized or grabbed, the creature must succeed at a DC 35 Escape check or an adjacent ally must succeed at a DC 33 Athletics check to pull them out.
