League-of-legends – Does Rylai’s and Spellvamp apply on Continuous Magic Damage effects

The Spell Vamp portion of the LoL Wiki and my own experience show that

[Spell Vamp] works off of activated item effects, summoner spells, and abilities, regardless of the type of damage done.

Therefore, items that give proc effects to attacks like Bloodrazor, Wit's End, Malady, Wriggles etc, will NOT grant the user health through spell vamp.

On a side note, Ezreal's Mystic Shot (Q) applies on hit effects, including but not limited to, lifesteal.

Blind affects auto-attacks only. Instead of damage numbers, a yellow "MISS" will display instead.

Blind interacts oddly with ON-NEXT-HIT spells, like Garen's Decisive Strike and Xin Zhao's 3-talon strike. The Auto-attack damage is negated, but any spell effect still goes through.

This means, for instance, that Xin will knock your champion up on a 3rd hit, even when he's blind.

"Blind has no effect on Lee Sin the Blind Monk."

In an April Fool's video, Riot joked that Lee Sin was immune to the effects of blind, but this is not the case.
