Action: Field of Roots
Your eidolon extends their roots underground to entangle and possibly damage all foes nearby. All enemies within your eidolon's reach take damage of the same type and amount as your eidolon's most damaging Strike, depending on their Reflex saves against your spell DC. Any ongoing effects of the save last until the enemy either Escapes or leaves your eidolon's reach. After using Field of Roots, your eidolon is Immobilized until they take an Interact action to detach from the ground; this also ends any remaining effects on enemies from Field of Roots.
