Luden's Echo has a game breaking bug.....
It just doesn't even proc on some skill lol...............
I was playing AP GP and I got it and it didn't even proc when I used my Q.
"UNIQUE Passive: Gain charges upon moving or casting. At 100 charges, the next spell hit expends all charges to deal 100 (+15% AP) bonus magic damage to up to 4 targets on hit."
"the next spell hit"
This means that It should proc on GP's Q. I thought that maybe it only worked when you dealt magic damage (which is not specified in the item) so I figured maybe when I bought lich bane, making my Q do magic damage, that it would proc. But it still wouldn't proc.
Not sure if this is a bug or the item description not actually telling us the correct information.
