Battle Companion

Feats

At 10th level, you can summon a battle companion. This ability functions as summon nature's ally V with a duration of 1 minute. This ability can summon only one animal, regardless of the list used. For every 2 levels beyond 10th, the level of the summon nature's ally spell increases by 1 (to a maximum of summon nature's ally IX at 18th level).
