SYSTEM NOTE: EARTH MOVER
You gave up turning into animals in favor of turning into a mountain. Roots, spikes, and shifting ground answer to you. You are slow to anger and impossible to move, which also describes most geological features and several of your teammates.

Earth Tremor is not required for this build. Instead, always prepare the 2024 spells Entangle and Spike Growth, describing them as roots and fractured terrain.
