RUSLAN / IN-GAME DECISION

How I decide

«An early item should win a trade while the lane still allows it.»

Ruslan UkrainskyiSpeaking through Rodya
01 Situation
The hero can regularly attack an opponent and use the orb's current properties.
02 My decision
I invest for immediate lane tempo, not just a distant slot in the build.
03 What I avoid
Delay using an early purchase until its small effect no longer decides the fight.

Valve notes

  • The armor reduction does not stack with the effects of Orb of Blight, Desolator or Stygian Desolator.

Game effects and recipes are a snapshot of official data. My guidelines are choices for a task, not a promise of the same build every match. Values for several stages, where present, are separated by ‘/’.
