Blackrazor

Blackrazor is a longsword with powerful enchantments but an evil nature. It is offered to the protagonist of the game in the test of greed in the Pocket Plane near the end of Baldur's Gate II: Shadows of Amn. They may either choose to keep it, benefitting from its power especially if and when their story continues in Baldur's Gate II: Throne of Bhaal, or choose to relinquish it, avoiding a fight and passing the test in the "good" way.

Blackrazor has a +3 enhancement bonus, and when wielded grants regeneration and immunity to Charm and Fear effects. It has a chance with every hit to drain the target's life force (levels) and convert it into healing energy and a temporary boost of speed and strength for the wielder.
