Weapons we put it on

Contagious Spread is in the recommended build on these guides; the tile opens the full build with every mod card.

Tips that save runs

  • Shotguns with high base damage for increased Toxin scaling.
  • Shotguns with high status chance to apply Toxin procs.
  • Shotguns used in builds that combine Toxin with other elements for Corrosive, Viral, or Gas.
  • The mod increases Toxin damage only for shotguns.
  • It provides a flat percentage increase to Toxin damage.

Mistakes that waste runs

  • Players might incorrectly assume it applies to all weapon types.
  • Players might confuse it with mods that add elemental damage types other than Toxin.
  • Players might not realize it only affects the Toxin damage component, not overall damage.
