Description: You can channel the power of nature to gain mastery over plant creatures.

Prerequisites: Can Cast Speak With Plants, Plant Defiance

You can rebuke or command plant creatures as an evil cleric rebukes undead. To command a plant, you must be able to speak with it via a speak with plants effect, though you may do so mentally if desired. This ability is usable a total number of times per day equal to 3 + your Charisma modifier. You use your highest caster level to determine the level at which you rebukes plants.
