Firetooth +3 (known as Fire Tooth +3 in BGII) is an enchanted throwing dagger +3 which returns to the wielder after being thrown. It deals 2d4 +3 point of missile damage and 1d2 points of fire damage. It has -3 THAC0 bonus, a speed factor of 1 and it weighs 1 lbs. The dagger can only be thrown once each round. This item appears in Baldur's Gate II: Shadows of Amn and Baldur's Gate II: Enhanced Edition. It can be bought from the weapons merchant in Ust Natha.
This throwing knife is imbued with magical fire, and was supposedly carved from an extracted red dragon tooth. Tavern tales suggest that the beast is still alive, her anger fueling the enchantment within the weapon. Though fanciful, the story is consistent, and it is said the dagger returns to the thrower "as though on wings."
