Dasken's personality is always fighting, an dhis stamina is at the utter maximum. In fact, all of his stats (excuse the comparison to the video game) might as well have 252 EVs and 31 IVs. He isn't going to run out of stamina for a looooong time, because he's also gotten stamina from his aura, and his armor, as I mentioned before, perhaps not as specifically, as an Assault Vest built into it. He is very resistent to attacks, but not immune. Try and find a weak spot, but it'll be hard.
It may not even be on his body!
