You draw upon the life force of your natural surroundings and coalesce it into a semi-transparent wolf-like form, roughly 3 feet in height. The wolf guardian is not living, nor is it a spirit, ghost, or any other form of undead, just a magically molded force. The wolf guardian constantly circles you, staying within 5 feet of you at all times. Any enemy that makes a melee attack against you draws an attack of opportunity from the wolf guardian. It can make one attack of opportunity per round, plus one attack per 5 additional caster levels (2 attacks per round at 10th level, 3 at 15th, and 4 at 20th). The wolf guardian attacks as a wolf (see the Wolf) using your BAB, and gains an extra +1 to damage at 10th level and every 5 levels beyond. The wolf guardian makes no other attacks other than the attacks of opportunity it is presented with.
