Like a Rock — Passive : Before they make their first attack in a fight or after they become Hidden, the Elemental is indistinguishable from other rocks until their next attack or a PC succeeds on an Instinct Roll to identify them.

Rolling Thunder — Action (Fear 1) : Spend a Fear to roll and tumble in a straight line to a point in Far range. Every PC within Melee range of the line must make an Agility Reaction Roll. On a failure, they take 1d12+4 physical damage and mark a Stress. On a success, they take half damage.

Surprise Slam — Action : If a PC moves within Very Close range of the Elemental while it is Hidden, it can move and make a standard attack with advantage against that PC.
