im a people too
e.g., will spell vamp give health back when you use something like Quinn's E - an ability that deals physical damage?
All abilities (even true damage) are affected by spellvamp unless it specificly says applies On hit effects or is an autoattack modifier (-jax W), in which case it uses lifesteal.
Like OneMillion said it will work with all abilities. So if mid or support or whatever buys WotA it will help out the entire team but of course don't buy WotA on Quinn just for spell vamp.
Thanks for the helpful information!
