You guys forgot about Nevermore.
Ohwai-

Needs more Nevermore.
Not Nevermove.
NO

You guys are missing the joke, Nasus is in the game, Nasus has some aspect of soul stealing(siphoning?).
Do I even have to mention Mejai's Soulstealer? Mordekaiser?
He's saying that Riot at some point dabbled in soul stealing as a means to accumulate wealth or power, but that it didn't pay off.
Spanish Inquisition probably roughed them up quite a bit

Darn I wanted to see an ult similar to Shadowfiend in Dota. Soul collecting!

Using souls like you use mana only it only replenishes when you kill something is not very good because you would need to farm to be able to do anything. Gaining souls when you kill something that passively boost your damage/health/AP/Q like nevermore/cho/veigar/nasus already does isn't something that riot's opposed to, I hope.

How can one keep respawning with new souls?
Does that mean your (champ's) soul is immortal and outlives your death but when you are respawned you are assigned a new soul?

The soul eating logic hurts.

I wonder if each soul from the same feeding champion tastes different.
