Conjure Minor Beast

You summon a beast within range. The beast must have a CR between 0 and 1, and can't be a Medium or larger creature. The beast follows your command during and out of combat. If no orders are given during combat, it fights for itself. It is similar to any natural creature. When it drops to 0 hit points or when dispelled, the creature is reduced to dust. When casted at a higher level, the max CR goes up by one each level. When your character reaches 10th, 12th, and 16th level, the max size goes up by one.
