Shredder

Shredder is a common mod for primary shotguns that adds Slash damage, reaching +90% on rank 5. It is the go-to choice when you want a shotgun to build bleed procs, since Slash ignores armor and stacks nicely with high pellet counts.

The mod has existed since Update 11.0. You can farm it from the enemies on the drop table of this page or roll it from transmutation. Combine it with other physical damage mods only if your shotgun has a decent Slash share; otherwise the bonus is wasted on pellets that mostly deal Impact.

Shredder was added with Update 11.0 (November 2013).

Shredder is tradable, see the current prices in the market box above.
