For stress dice, yes.<br/><br/>Stress works as follows, unless I misunderstand:<br/><br/>If you try to add a die that's higher than what the target already has, it increases to the higher die.<br/><br/>If you try to add a die that's lower than or equal to what the target already has, it goes up by a level.<br/><br/>If it exceeds d12, they're Stressed Out, effectively out of the fight one way or another.<br/><br/><br/>The other person also gets to roll your stress die if you're taking stress, because it's effectively a penalty against you.  However, PP can be used to make it a bonus on your half, which is one of the many things that PP can do.
