In-game description
"Kundane +2: Sword of Quickness

Disfigured as a child, Dramnek Olk was ostracized and ridiculed by his peers. In his loneliness he spent many hours alone on the hills overlooking Trademeet. A nearby wizard, Galloma discovered the youth and found in him a kindred soul. The two fast became friends; master and apprentice. Galloma died before Dramnek's tutorage could be completed however and the youth found himself once more alone in the world. Eventually he made his way to the streets of Athkatla. There he became a cutpurse, augmenting his thieving skills with the little magic he'd learned from Galloma. Eventually he crafted this sword, which enhanced Dramnek's weak physical body. This weapon has no speed factor."
