Go Nashor, Rabadon, Runaan, Zhonya, Void Staff, instead. With 500 AP you get to 2 AS and deal 115+11%MaxHp on-hit, that means at least 335 damage on-hit + AD, so around 430 damage on primary target and 390 on secondary ones.

Even with crit you get to, say, 300 AD, 50% crit, meaning 300*0.5*2.5+300*0.5 = 300*1.75 = 525+6% MaxHP = 645 damage (with the same assumptions).

Sure, you get greater single-target damage, in the AP version you deal damage to 3 different targets and have a much greater burst.

My advice would be to rise the ither skills first and buy AP, then go for nashor and hurricane once you have enough AP
