So much sustain? There's what already... As you see, I did proceed ability by ability, as I did when creating Haramn, with healing as rewards for risk (Assimilation), or because it synergizes with another effect (Abyss Whirl). As for Chaos Call, with a 60% movement speed, you will hit damage cap. I agree that this should be less good on ranged champs, but Haramn has no reason not to be rewarded for smacking the enemy in the face, as he's already kitable as hell.
 * Assimilation: Eating a corpse restores . Welp, that's to compensate for the extra harass he's going to take trying to farm corpses on top of having to farm the live minions.
 * Carnage has double lifesteal. Welp, I see no reason not to reward him for reaching point-blank and having the stacks. Plus it only gets effective if you get lifesteal on him.
 * Abyss Whirl gives Haramn life equal to 50% of the damage dealt. Well, considering how little damage it deals, it won't give Haramn back that much. This new effect is to make Haramn look less big by raw damage numbers, and reward him with healing for that health regen CDR effect, not with damage.
