Bought it and got Shiva, not too bad considering that the next boss should be a fire type. I think its one of the few offers worth getting, since the "guranteed to get an SSR kami or eidolon" is technically "free" since you get 1k worth of potions and 1k worth of seeds. So its basically like if you bought a normal 3k gacha. My only issue now is wondering when will the next time be for this offer.
