NOTES

• The attacks first apply the debuff, then their own attack damage.

• If both melee and ranged hero with Orb of Corrosion attack the same target, the values of the first applied debuff are used and refreshed.

• Deals damage in 1-second intervals, starting 1 second after the debuff is applied, resulting in 3 instances.
  • 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).

• Works against buildings and allied units. Does not work against wards.

• 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.
  • If both debuffs are present, Orb of Venom's debuff does not slow or deal damage.

Recommended Heroes

Melee heroes that naturally buy Orb of Venom and rely on physical damage:

Others

• Also works very well on Abaddon, as it has very good synergy with his passive Curse of Avernus
• Does really well when combined with Lifestealer's Ghoul Frenzy and Rage

Trivia

• Corrosion's debuff does not have its own particle system and uses the particle effects of Thunder Clap's slow debuff instead.
