I didn't even know the Kraken could respawn, the only ranged damage dealer I had on my team was the healer, at least the only one that could reach said Kraken, who had maxed out intelligence and hit like a truck, but just didn't have enough to completely eradicate it. I wasted probably 3-4 complete turns trying to move my melees into position so that I could kill off the Kraken, eventually gave up, insta killed Braccus Rex.
