@tobiax Sorry if I'm a bit late pointing this out, but going straight for the offensive on Moon PROBABLY isn't the best possible tactic you could go with here. You're not going to accomplish a tremendous amount on your own, regardless of how powerful Rodendramon might be as an individual: most you're going to accomplish is catching Moon's attention and getting everyone killed along with Rodendramon whilst they're still stuck as sitting ducks.
If you wanna argue that it's in character for him to go straight for Moon, then fine. Just edit a bit so that there's more room for error with the attacks he's firing off, then someone or something can stop him from triggering a bad end?
