Environmental Balance [F] (evocation, primal) Trigger The spirit turtle begins their turn; Effect The spirit turtle harnesses their connection with the world around them to augment their attacks. They choose acid, cold, electricity, or fire. The energy damage dealt by their Strikes and Unbalancing Stomp changes to the selected energy type.

Unbalancing Stomp [>>] The spirit turtle makes a foot Strike. Whether or not the Strike hits, the stomp creates a shockwave on the ground in a 15-foot burst centered on the target. All creatures in the area other than the spirit turtle take 10d10 bludgeoning and 4d8 energy damage and are knocked prone (DC 41 basic Reflex save). Creatures that critically succeed at their Reflex save are not knocked prone. The spirit turtle can't use Unbalancing Stomp again for 1d4 rounds.
