Area of effect (AoE) spells only apply 33% of the listed spell vamp. And yet in Hextech Micro-Rockets description on Heimers site it says:
 * Abilities such as Fox-Fire and  Hextech Micro-Rockets are classified as multiple single-target projectiles, and will apply 100% of your spell vamp. Whether an ability is classified as such is case-by-case. For example,  Mace of Spades is classified as AoE despite being similar to  Hextech Micro-Rockets, unless, of course, Morde only hits a single target, then it is classified as a single-target ability.

Hextech Micro-Rockets procs spell vamp and Rylai's slow similarly with all multi target spells and abilities with diminished effect.

So what is the truth?
