History of Shattershafts

Shattershafts is a Volatile bow mod from Arms Week (bow-themed, in Renegades). Arrows and bolts split into several projectiles after a short distance, working like a shotgun spread: each does less damage, but close-range total is more than double.

You earn it by handing in quests to Ada-1. Others are Tungsten Bowstring and Jumpshot.
