Corrosive

Corrosive weapons cause splashes of acid to corrode at enemies. Corrosive weapons are effective against heavily armored enemies, like Skags or Spiderants. When a corrosive weapon's effect triggers, the enemy will start to take damage over time. The damage is less than that of a fire weapon of the same level, but the corrosive damage also makes the enemy more vulnerable to all damage while it is in effect. Enemies that die to corrosive damage will melt away.
