Frostbrand is an enchanted scimitar wielded by the famous hero Drizzt Do'Urden in Baldur's Gate, Baldur's Gate II: Shadows of Amn, Baldur's Gate: Enhanced Edition, and Baldur's Gate II: Enhanced Edition. There are two possibilities to obtain this weapon: to kill the drow or to steal it from him. The weapon deals 1d8+3 points of damage, has a -3 THAC0 bonus, a speed factor of 2, and weighs 3 lbs.
Equipping this weapon gives +50% fire resistance. With other items, gaining more than 100% fire resistance will allow a character to heal from incoming fire damage rather than being hurt by it.
Drizzt also caries Defender.
