- The damage dealt is direct HP Removal, so it does not trigger any on-damage effects, but it is lethal.
- Can deal up to 15 damage (before reductions).
- Applies heal reduction, health regen reduction, lifesteal reduction, and spell lifesteal reduction on the target.
- Corrosion does not stack with the slow and damage over time of Poison Attack.
