On my team I have a darmanitan, after the elite four you can get a ragecandybar which can be used on the statues outside relic castle, doing this make a wild darmanitan with zen mode as its ability attacks you, zen mode makes it have terrible physical attack and amazing special attack, and it only activates when the darmanitan has less than half health left.
What I want to know is is it worth catching it and reaplacing it with my current darmanitan?
