Toxic Barrage is a mod that increases both the Script error: The function "Proc" does not exist. damage and status chance of a shotgun by 15% per rank for a maximum of 60% at rank 3.
Previously a limited-edition reward from participating in The Cicero Crisis, this mod can now be acquired as a drop by killing Corrupted Vor in level ≥40 Orokin Void missions.
Notes
Toxic Barrage is additive with similar mods. For example, a Strun with a max rank Toxic Barrage and Shotgun Savvy will have a 20% × (1 + 60% + 30%) = 38% status chance.
