Abilities

Passive: Corrosion

Your attacks reduce the target's armor by 3, slows their movement by 16% (6% against melee targets), and reduces heals, health regeneration, lifesteal and Spell lifesteal by 16% for 3.0 seconds.

Additional Insights

Armor reduction does not stack with its components, Desolator, or Stygian Desolator.
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!
