Does Ludens Echo affect the primary target? How does it interact with Karthus's Ult?
If I read Luden's Echo's passive correctly, it deals it's damage to the primary target and nearby secondary targets. How does this work with Karthus' Ult, Requiem? Does every enemy player get hit with Luden's passive effect? Or is it a randomly chosen enemy? Or does Ludens Echo not affect the primary target and only the nearby targets are affected?
