A friend of mine is starting a high level campaign soon (starting at level 19), and I decided to use a character concept I've had for a while, which was a Dwarven Drunken Master monk who drank himself blind after he drunkenly engaged in a drinking contest against Cayden Cailean in a bar. Cailean left the monk with a refilling mug of Dwarven ale for his courage, even though he lost. He has a GM approved drunken blindsight ability and a bonus feat as recompense.
Then I realized we needed a tank/meatshield, and while a Drunken Master monk wouldn't be my first choice, I already had the concept planned out, so I added Monk of the Sacred Mountain archetype for defense type stuff. Finally, for mobility's sake (we will be in Hell after all), I took aspect of the Ki Rin with Monk of the Four Winds archetype and an immovable rod for flying 80ft per round. (It's all approved)
I'm not looking to totally optimize, but the campaign is focused around a second edition adventure that he keeps saying is going to be, "balls hard". I was following treantmonk's guide to Monks, but the archetypes make a few of his feat suggestions slightly unusable (Need to get stunning fist as a regular feat to make proper use of Medusa's Wrath), so I was hoping someone might be able to give me some good feats to compensate.
(I don't want to give up any of the archetypes, because I like the way they work for me, and a few feats are tied up with bull rush focus, but I'm interested to see what the boards can come up with.)
