If you deal 50 damage with a single-target ability and have 1% spell vamp, you will heal for (50 x .01) health which equals 0.5 hp. The heal amount is based on the damage that you deal not the number of hit points that you take away from a target. In other words, you will still heal for 0.5 hp whether you hit a target that has 500 health or 1 health.

However, Rammus' Defensive Ball Curl procs Spell Vamp as a multi-target spell, so it only applies 33% of your current Spell Vamp. SO...with 55 damage at max rank (not including armor) you would heal for (55 x 0.0033) which equals 0.1815 hp.

Not really worth it, if you ask me. :)
