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!
