Nasus rework idea

Passive, soul siphon: Nasus deals bonus magic damage on his autos. His autos also heal him based on the bonus damage he does to his enemies. Will either be a flat damage and lifesteal or based on %max health, something like 2% at level 18(heals for 40 health and deals 40 bonus damage on a 2000 health target.)

Q, Siphoning strike: Nasus empowers his next auto to deal bonus physical damage. If he last hits he steals the soul of the target into the cane to permanently increase the damage on his Q. Caps at 300 bonus Q damage. Once Nasus hits 300 bonus damage his last hits with Q will instead heal him based on the targets max health as his cane cant absorb the soul, he does instead. Q cd reduced by 0.5 seconds late game.

W, Wither: Ages a target over time slowing their movement speed and attack speed. The rework would change nothing.

E, Spirit fire: Nasus lays down in a circle spirit fire that deals magic damage, half right away the other half over time. Reduces enemy armor while inside it. The rework would change nothing except reduce the mana cost to 70/80/90/100/110

R, fury of the sands: Same exact thing as live except now instead of gaining bonus AD when damaging enemies with R his Q absorbs the enemy health into Q damage. Every 50 max health he steals gives his Q 10 bonus damage, capping at 500 bonus damage from his R(if my math is right 5000 health has to be absorbed).
