Playing more I'm really confused over how other elements work. Like, my cards just seem to vanish without me using them? Also some enemies just don't kill me when they should be able to, is it random?
Hey, you can read the Manual from the settings menu.
Cards only display when you either have enough energy to use them or there are valid targets. If not they get greyed out. Each tile has different Items associated with them so once you change your position available items also change.
