nice effort on the build description. This is an odd build, well different at least. your 2 doran's rings are very unusual I feel you do it for the health factor and there are other options for that. I do like how you did put a lot of thought into it though, and if I could just suggest maybe a deathfire'g grasp in there to add an extra move its pretty nice. Also just wanna let you know that you said armp instead of magic pen in a sentence somewhere, just a heads up! good build.

good build, pretty much the same as mine, except i dont use ghost, i use clarity so i can spam my spells alot more, and its awsome for those moments in team fights when your like man i wish i had mana...

also, will of the ancients is ehh...40 ap awsome more spell vamp awsome, but when you break 400 ap...u dont need more spell vamp one pool will take u to full hp.

id get a rylias for the slowing effect from the pool, and for that initial slow when you pop your ult, plus its double the ap and more hp...

other than that, dead on man. gg
