I play Ziggs and very favor of Rabadon Deathcap and Void Staff which give extra ability power in percentage of champion's AP instead of a specific number.
So my question is what are LoL items that give extra in percentage
power to a champion stats?
p.s.
Well I need items that improve in percentage
for any kind that profits a champion.
Best Answer
The follwing are a list of (most) items that provide stats in the form of a percentage.
Attack Damage (AD)
Ability Power (AP)
(Void Staff actually only gives +80 flat AP, you seem to have mistaken the 35% magic penetration it gives for something else.)
Cooldown Reduction
This is not really providing cooldown reduction as a percentage of cooldown reduction, but I left it in here anyway.
Health
Other stats are always provided for by items as a percentage of base amount:
If anyone else has any to add that I have forgotten, please say so.
