My iPad is now a KA game system for at least the next day or so. Unless the game crashes. I still have 54 boxes left and I've attempted to open 4 since the event officially ended. All sorry's btw. I'm hoping to get some HP out of it at the very least. I could care less for more worthless units or allies.
Edit
Is it even possible to open these boxes without paying with gems after the event is over? I'm now 0-5 in attempts with the middle option since the event ended.
