Ryze E spread does not proc Spellvamp at all.
Just went into a custom game to test out spellvamp functionality on Ryze. Was happy to see that a Q into multiple enemies via spell flux grants full spellvamp on the first target hit, however, when initially making the E spread, only the very first target grants vamp at all. This makes running Ravenous Hunter a lot less viable. I'd like to see this fixed.
