So I've been trying to get the Dragon King down and working on different strategies and every time I bite the dust, I have to remake the decoy princess. I get back to the arena I've built in less than a minute and he's not there. After a few tries, it's a giant waste of resources. This doesn't just apply to the 3rd tier boss. Bosses should stick around after you respawn for a certain amount of time. Because 200 titanium bars and 6000 pixels later, it's just a touch frustrating.
