Splinter Weapon

Usage Notes
With multiple-hit attacks such as Barrage, Splinter Weapon will affect every hit, however it will not affect any one foe more than once. For exampe, Barrage may hit three foes, and any foe adjacent to one of those foes will take damage from Splinter Weapon, but a foe adjacent to two foes hit by Barrage will not take the Splinter Weapon damage twice.

Note that this damage is only dealt to foes adjacent to the target, not to the target itself.
