Abilities

Passive: Corrosion

Your attacks reduce the target's armor by 2, slows their movement by 16% (8% against melee targets), and reduces Health Restoration by 16%. Lasts for 3.0 seconds.

Additional Insights

  • Armor reduction does not stack with its components, Desolator, or Stygian Desolator.
  • Stacks with <item_skadi></item_skadi><item_assault></item_assault>
  • What's even more amazing is that this orb's effect sticks around for a few moments, keeping your enemies feeling the burn even after the initial hit. It's like leaving a lingering sting that makes them think twice about messing with your hero!

Heroes with Orb of Corrosion as Core Item

 undefined
A core item in the laning stage to slow down enemy heroes and do more damage with your right clicks by reducing the armor of your target. Also works well against tanky heroes by reducing their health restoration. The {agility} gain also provides armor and increases the damage you do with the Backstab right clicks.
 undefined
A core early game item that increases the damage of your Sleight of Fist that allows you to boot out most heroes out of lane. The slow allows you to stay on top of your targets and chase them down while the healing reduction scales throughout the game.
 undefined
An upgrade for {orb-of-frost} to dominate the lane with more damage with minus armor through right clicks and stay on top of enemy heroes. Gives you a better chance to activate Jingu Mastery and deal massive damage with Boundless Strike.
