Example of a corrosive weapon.

Corrosive weapons are capable of splashing acid onto multiple enemies, causing them to dissolve. Corrosive damage is particularly good at eliminating Crimson Lance, turrets and vehicles. Similarly, in Borderlands 2, Corrosive damage is extremely useful in dealing with loaders, Hyperion soldiers, constructors, and armored enemies of all types (now indicated by yellow health bars). When the elemental effect triggers, the target gains the Corrode status, taking additional corrosive damage over time. The death animation from corrosive damage is a grisly scene in which green acid eats away at the victims' flesh or plate until they are completely dissolved.

Corrosive acids can be formed by many objects and creatures:

  • Guns are the most obvious, as corrosion can be found firing from any weapon type.
  • Barrels which are green in color contain corrosive acid and explode, releasing a large splash of acid when ignited.
  • Grenades can also deal corrosive damage if a "Corrosive" upgrade is on the equipped grenade mod.
  • Shields can also produce an acid burst or nova when depleted. These shields can only be manufactured by S&S Munitions
  • Creatures can also have the ability to generate acid. All creatures capable of creating acid are also immune to acid.
  • Action Skills can be enhanced by a corrosive artifact, creating the corroding effect when used on enemies.

In Tiny Tina's Wonderlands, corrosive damage is renamed poison, but keeps the basic mechanics of the corrosive element from previous games in the series, with increased damage to armor and reduced to other enemy health types.

Poison damage effectiveness varies based on both enemy health type and the current difficulty setting.
