There's this post on GameBanshee's forum that talks about it. I put the files in there but it never worked, but perhaps it may give a clue.
"B20's BG2 & ToB Links Central
iv just completed a large and long overdue update.. iv included lots of new links as well as updated some old stuff..
also if your interested mysticsyn has been kind enough to put up some little mod files for me at his site..
http://mysticsyn.tripod.com/Mods.htm they are..
- a corrected version of the baldurdash/teambg grand mastery patch as well as a version that i use that continues adding 1/2 attacks every 7 levels for warrior types.. it says that it restores gm to what it was in bg1 and iwd.. going from 3/2 to 2 attacks.. but instead u go from 3/2 to 5/2 attacks.. pernickety i know.. especially since technically its a cheat anyway.. but if u want the corrected version u can download it here..
- a greater wolfwere fix by cinreth as well as a saved game just before u meet the infamous one in windspear hills dungeon.. in case people havent experienced the problem and want to see for themselves.. also iv included a screenshot shows me doing over 200 damage to the gww in 2 rounds!.. with his tab label still at "uninjured"..
- a 'fix' for the red dragon scale in tob where it can no longer be worn with items of protection of +X.. i know this annoys a lot of people.. finally iv included a tweak that allows all magical armour to be used in conjunction with items of protection.."
