League-of-legends – Is spell vamp triggered by true damage

league-of-legends

Is spell vamp triggered by abilities that do true damage? For example, does Nunu's consume heal more if he has a Will of the Ancients?

So spell vamp isn't about Magic/Physical/True damage, but rather about "Abilities." The term Abilities here is meant to be distinct from "Auto-Attacks" (which benefit from life-steal). With a few notable exceptions all attacks fall into one of these categories: Auto-Attacks or Abilities.

This means that things like: Feast and Consume benefit from spell vamp. cite, cite, cite, cite

Now it's worth noting that there is a class of abilities, "On-Hit," which are not clear as to whether they fall into the "Auto-Attack" or "Abilities" category. Some of these will benefit from life steal (eg. Blitzcrank's Power Fist), some will benefit from spell vamp (eg. consuming a mark from Akali's Mark of the Assassin), and some will benefit from neither (eg. Irelia's Hiten Style), though the auto-attack portion will still benefit from life steal.
