I am currently running an evil party in BG1 and have 3 cursed items equipped on 3 different characters... I guess they are an unfortunate lot!
"Big-Fisted Belt" - Kagain - Intelligence hit does nothing to him, and the 19 strength from this coupled with the 18 dex from the Gauntlets of Dexterity, make him the ultimate meat tank.
"Claw of Kazgaroth" - Dorn - The Con hit doesn't affect him (except by making him fatigued more often from travel) and the saving throw bonuses therefore outweigh the negatives on this item. Some people never buy this, but I always do.
"Kiel's Morning Star: +3" - My Main - Running a Half-Orc Fighter/Cleric. This in her main hand and the Thresher +2 from Sorcerous Sundries in their off-hand hand, gives her a wicked +3/+2 Dual-Wield combo. Couple this with the increased damage and THAC0 from berserking, the immunity to several spells (including Charm Person) and increased saves against others, its pretty cool. Yeah, Yeah you can attack friendly targets if you're not careful. The key is to play smart. Here's some tips I've found for using a cursed-berserking weapon:
- The effect doesn't last SUPER long. Just until all enemies (red bases) are slain. Then (give or take 5-10 seconds) they will return to normal. The key is to hurl the berserking character at said enemies, and have your other party members give them a bit of room. If you play it right, they will only attack enemies and then once they target a friend you just jog around for a few seconds until your main's yellow base changes back to green and ur good. Sometimes I cast Invisibility 10' Radius, and only have my berserking character attack for awhile. They can't see the other party members to attack them, so they only really attack enemies.
- If you are playing a Fighter/Cleric as a berserker, cast your buffs, etc. BEFORE combat. You won't be able to cast spells once the bloodlust hits....
- You (most of the time) have a few solid seconds to command a character using a cursed-berserking weapon, before the status over takes them. Use this to command them to attack who you want, or to move them, as needed.
- Keep a "Remove Curse" spell memorized and handy on a mage. Helps in some battles to have better control of your character.
- Keep a secondary weapon in the primary slot, in case you want to REM CURSE at a given time. Example: My character has Kiel's and Thresher but I keep another +1 Morning Star in my primary slot just in case I need to ditch Kiel's for a fight.
- If you're doing battles in a town, where there are innocents... you may want to unequip for a bit.
Really - As an evil party - Its just fun to berserk and go crazy. Can it screw you? Sure. But if you play smart its fun and a bit of an added challenge to the game.
