Do you even know what you're trying to suggest? Life steal items are extremely rare to find, and the very few life items that does exist, are usually sold overpriced. Let's say you're a barbarian with 3500 hp, with a cursed weapon. Every hit you deal sacrifices 3% of its hp, making him lose 105 Hitpoints! (oh god, that's alot isn't it?) Still convinced that a mix of life stealign items would be any helpful at all?
heres a story of a fellow barbarian hero named jack, that lived between Year 97- 121 after the war of the spear had ended.
Jack is sitting outside his glorious garden while his small mind is pondering over lives great mysteries while meditating in peace and harmony with its surroundings.. Jack thought that this was the perfect day for having a tea drinking party with his fellow female rogue friends! They are all enjoying the day when out of a sudden they hear a shrieking sound out of nowhere, seconds later a paladin is seen running in furious anger and rage towards jack. The tea drinking rogue girls are struck with fear and decides to flee the battle scene, leaving jack alone.
Jack quickly retaliates and decides to use a combo consisting of a:
Charge, Normal hit (-105 hp), power attack(-105 hp) , bleed (-105 hp), normal attack (-105hp) , normal attack (-105hp), power attack(-105hp).
As you can see, our poor little Jack would lose a whooping 630 hitpoints just by doing this combo, while only repleneshing around 100 hp when striking a critical hit of 1k damage. (assuming hes wearing enough life steal items to even replenish that much hp)
Sadly, Jack the brave hero did not survive the ambush attack.. May he rest in peace.
