I believe this is a bug, but wanted to see if anybody else could confirm.
For a City Watch, I fought manually and hired Jack Sparrow. I coupled him with my four worst heroes. At the end of the first Round, he had enough energy to proc and then kill everybody.
However, he did not use his energy, and he never did. Rounds 2-15, the Round would start, he’d proc with the Black Pearl, kill everybody, and not lose energy.
Is this a bug, or is he really that OP that he generates full energy between every City Watch round?
