He's a level two Warrior, with a Passive and a Root. His passive causes you to get progressively slower and sluggish each time you're hit. His Root involves stabbing you in such a way that your feet get stuck to the ground. it's also an Anti-Air attack which will cause you to slam into the ground if you don't have any recovery skill.

Additionally Dunk Master is on the verge of leveling up, and should he be caught in a pinch but could get at least 30 more EXP, he'll have enough to go into level 3, which will grant him his Third Avatar Ability, restore his health and reset his cooldowns, and get a feat. I'll decide when that happens though, don't you worry.
