Darts are small throwing weapons with a range of 20 feet and three attacks per round (6 seconds), which falls under the missile weapon proficiency. It's equipped in the weapon slot instead of the ammunition slot and per inventory slot, the max stack is 20 units. Combined with the high attack rate and lower stack than ammunition, many inventory slots are needed to have decent supply of darts for a darts thrower.
This dart inflicts 1d3 points of piercing damage, weighs 0 lbs and has a speed factor of 2. This appears in Icewind Dale and Icewind Dale II.
