Overview of the Corrosive Blastsling.

Corrosive Blastsling Description¶

This Quen weapon excels at delivering Acid payloads that corrode enemy armor. It can be upgraded to deal more damage when fired while sliding or in mid-air.

How to Get the Corrosive Blastsling¶

You can purchase the Corrosive Blastsling from the Hunter who has set up camp in Scalding Spear. You’ll need a Thunderjaw Circulator which is an Uncommon Drop from Thunderjaws and a Large Machine Core which drops from large machines, such as a Tremortusk.

How to Use the Corrosive Blastsling¶

The Corrosive Blastsling is best used when fighting larger machines that are susceptible to Acid or Purgewater Damage. A great way to use this weapon is to begin with the Adhesive Damage to slow the machines movement, then switch over to the Acid Bombs to weaken their Armor before using a weapon that deal impact damage, such as the Piercing Shredder Gauntlet.
