Essentially, the key to this build is being aggressive in your play style, until you've reached 100 stacks of insight you should be literally punching everything in range. When it gets to the point where you can't safely punch in the lane, you wander off and you punch the merc camps down. The healing spirit ally will help keep you sustained when building your stacks on camps, worst case scenario you can always let the camp leash and go back at it with full health in a minute. If you're aggressive enough I've had this quest done by the 4 minute mark before. Once you've got your cooldown reduction your healing output and damage swings up dramatically! It's a super fun build and it puts out a surprising amount of damage as well. Happy Face Punching!
