So Chen I thought was ok at first but after playing him for a while, I realized he is pretty good. So I have decided to make this tank build and after multiple uses, have had an overwhelming success with it.

Level 1: I chose Regeneration Master this is to help keep up his health. It is important to either lane alone or along with someone else who needs regen globes to boost a certain talent so it's easier and you're helping the team out at the same time.

Level 3: Amplified Healing is a must just to increase all of your regeneration effects. Thus keeping you at higher health longer.

Level 7: Brewmaster's Balance is what I go with due to the fact that when you pick it up and are getting the health regen, you're already getting 22 health per second from this and at this point you should already have rougly 10 regen globes which gives you 15 health per second for a total of 37 health per second. I know it doesn't seem like much but early game it is and once your brew drops, you get the speed boost which will help you escape situations and prevent the enemy from getting xp off of you.

Level 10: Wandering Keg is more annoying than anything. Nothing gets me more mad then getting deep into a team fight just to be pushed back and separated by this. It is good to push back enemies and protect your team. On the other side of this coin, you can (with extreme skill) move behind an enemy and push them into your team in order to seal in that kill on the pesky Kael'thas or some other ranged hero that is a huge part of their team.

Level 13: Enough to Share is something to just help out your team by giving them a small shield. Thus giving yourself more team use than just being able to soak all damage.

Level 16: Bolder Flavor is needed due to the health regeneration having trouble keeping up with all the enemy hero's higher damage output

Level 20: Hardened Shield is used for the same reason as our level 17 pick. This being instant and not needing the brew to be activated is what makes it good.
