Is this even fun?

That video is not a very good one to base yourself. In KMS apparently boss damage 30% and 20% stack, so the guy has two 30% boss on the dagger and 30% and 20% on the katara. No other class can have that much (and getting that much is insanely rare and prolly costed WAY too much in cubes).

Well, the potential system existed right before I quit, so I know what it can do. That said, I didn't expect people to do literally 20 million DPS. pomegranate is nuts.
