I sent this into support asking them if it was a bug, but they told me they can't discuss the game design. If I were to have the opportunity to trigger an epic, say, Bladestorm, but there are no targets for it because I've killed the last nearby enemy, that trigger is just lost. I can tell because if I score a critical hit later on my turn, it does not trigger Blade Storm. I suspect this occurs for all epics, so you may want to look into that. Also, is this intended? Or is it truly a bug? Can a KI employee comment on this as to whether or not it's intended? Please also take the time to look at my other thread, Musketeer Shots and Hide.
