I believe Spell Vamp works at 33% of the listed value when dealing with AOE Damage.

So your really looking at a 4.95% Spell Vamp from Will of the Ancients on the AOE Damage of Siphon: ( [245+28] * <# of units hit> ) * ( 0.15 * 0.33 ) ( [273] * <# of units hit> ) * ( 0.0495 ) ( [273] * 6 ) * ( 0.0495 ) = 81 HP healed for hitting 6 units
