Kondar

Named after its original owner, Kondar is an enchanted bastard sword that is more powerful when used against shapeshifters, as well as growing warm in their presence. Its normal enhancement bonus is +1, the greater one against shapeshifters +3. It's carried by Aldeth Sashenstar in the game Baldur's Gate, and can be acquired from him by killing him in Cloakwood where he is first encountered, or by helping him there and later also helping him root out the dopplegangers infesting the Seven Suns, whereupon he will give it as a reward. Its property of growing warm in the presence of its prey is not implemented in the game in any way.
