So this PrC is really really awesome thematically but... it has some really lame features.

A one week cooldown on his summoning skill? When a level 5 barbarian is going to be almost worthless at level 15 when you're liable to get this skill?

Come on Paizo D:. If it's going to be that slow it should be epic, and if it's going to be that mediocre it should be times per day.

I really really want to like this class.
