Been struggling to kill The Master for months on nightmare roguelike. Saw someone else's advice to try antimagic and I hatched a plan to punch The Master to death out of spite. Long story short I went for a crazy antimagic brawler and managed to punch him to death with a single hp remaining. I even had to turn into a parasite to keep punching. I died immediately after from the leftover minions (antimagic wore off and regen wore off) but despite that I feel accomplished. This was my highest character ever. Here's to making it to the Far East.

My character for proof :)
