I just knocked him unconcious had 4 martial artist and 3 pack bulls the bulls had around 30 to 40 stats the martial artists had 40 to 50 all of them wore the full samurai armour and fog masks the equipment was standard to masterwork grade
I have the zombieland mod installed which just adds a load of zombies to the game (as well as some interesting uniques and locations) I never found bugmaster before but I was running away with my stealth character from a bunch of zombies when I stumbled into the tower. I sneaked passed the spiders and saw him just standing on the second floor with his back to me, I knocked him out and picked him up. Ran away with 87 stealth without the spiders ever even seeing me. Quick way to make money but it was a bit anti-climatic.
I had a guy run into the tower with 90 STEALTH TOTAL and guess what a skin spider immidiately saw him and they all started runing after him so I sent him upstairs and he also has 80 ASSASSINATION but guess what theres a BIG 0% chance.
Big problem with bugmaster fight is his ai. he prioritize medic action over actual fight which made him run to my waiting companions and ruined whole duel, was fun stll, just only half of fight was "duel"
