I was play and decided to curse a unit. It gave a casting time of 1, then the casting was done and left me with a screen with a wand cursor, so I know to cast the spell. That is not enough to let the user know to cast the spell on target. Maybe there should be some info-text saying "Select Target for Curse". This is mostly for new users who may say... hey I can't do anything my bar is gone, when really they just need to select a bad-guy to move on in the battle.
