Plus when I use increase mass I have near 700 defense. Ontop of this, im being healed 15pts every second for five seconds, which heals 75 (about the equivalent of 1 potion). Im extremely hard to kill. There's no point putting everything in offensive skills, since your normal damage is usually greater. By using one, you get the bones of the attack (knockdown ectect) without wasting the other 5 points you could use to be stronger.
