Natural Mystic

You are a student of matters both arcane and natural, and your studies of their relations improve your bonds to the natural world.

Prerequisite(s): Cha or Int 13+ (see special), nature bond and wild empathy class features, 1st-level Mystic Theurge

Benefit: Your levels in mystic theurge count as levels of druid for purposes of determining the power of your nature bond and wild empathy class features. In addition, once per day you may sacrifice a prepared spell or unused spell slot (for spontaneous casters) from your arcane spellcasting class in order to spontaneously cast a summon nature's ally spell as with the spontaneous casting ability of the druid.

Special: Your primary arcane spellcasting ability (Int for wizards, Cha for sorcerers and bards) must be 13 or higher.
