I think you can only reach -14 with Drizzt's armor (not sure). I use an elven fighter with
Helmet of Balduran
Cloak of Balduran
Ring of Protection +2
Ring of Free Action
Gauntlets of Weapon Expertise
Full Plate Mail
Large Shield +1 +4 vs Missiles
Girdle of Piercing
Boots of Avoidance
Long Sword +2
Of course, I don't have ToTSC.
