Bastard Swords are one-handed weapons which require 11 Strength to wield them and only bards, fighters, barbarians, paladins and rangers can wield them. In Icewind Dale, these weapons fall under the great sword proficiency. The weapon inflicts 2d4 points of slashing damage, has a speed factor of 8 and it weighs 10 lbs.
Also known as the hand-and-a-half sword, the bastard sword derives its name from the fact that it is halfway between the two-handed sword and the long sword. The bastard sword has a double-edged blade and a long grip, which can accommodate both hands if preferred. The overall length of the bastard sword ranges between four feet and four feet ten inches.
