(Item Concept) Light Of The Paladin
Light Of The Paladin 80 Attack Damage 20% Cooldown Reduction
Unique Passive: Damaging enemies with spells that deal physical, true or percentage damage will heal you for ()% of the damage they dealt. Effects are reduced against monsters and minions. Lifesteal no longer works for you. (Or reduced by a large percentage)
Note: This will apply a light aura on your character to symbolize the light of a Paladin. That or a symbol beneath your character like Abyssal Sceptre. This is a lifesteal alternative and an AD spell-vamp alternative.
Edit: Fixed some wording, as apparently I worded the passive confusingly.
