alright, so if i'm understanding the Marks right on him, if the person meets the criteria stated there he can choose to "Mark" them without any indication and use one of the powers. the only thing i've got left is a wording issue:
"There is a 0.5 second delay between changing marks (so a half a second time where a target is not marked)."
that can be read two ways. the way i initially did was that .5s is needed to change the mark on a target. therefore during that .5s, it's still using the same mark as before.
the other is that if you're changing marks, one will end, half a second minimum needs to pass, and then the other can be applied.
