good build

Yes, I wrote about getting it but forgot to mention it in the late game. I usually get it near the end of the game because the extra attack speed you have from the greaves isn't doing much anymore due to other AS items but the Tenacity is good. I've included it now, thanks for mentioning it.

Oh yea... Mercury's Treads!!!!!!!!
I swear, you will love these boots on him. Counter to mid-laners + vital tenacity that is really needed due to you getting CC'ed a lot.

Adorable build to my eyes :D Love this way of playing TF. F lame AP builds ;)

My suggestions,

Get Exhaust as a primary summoner. It's so great with TF.
Wit's End should be a part of main build, hands down. It's the best mid item for him (considering mid's full of AP carries)
I'm more used to maxing PaC first mainly due to burst damage, moarrrr stun/easier farm, but your skilling sequence is great as well.

Nice to know that some people play TF this way too :) Best way, imho :D

In my honest opinion, I'm not with you at point you link Wriggle's Lantern with jungling. You don't need to be jungle but sustain in lane in example with a free ward to evading ganks to get this item. I take this item with some champs in lane and works perfectly.

Regards.

I just don't get the point of getting both wriggle and madred. Since you are ranged ad carry jungling isn't your job. The point of getting wriggle is a bit weird. Madred can be fine against tanky-teams but taking wriggle? I just don't get it. Well, I haven't tested it so perhaps that's fine but there will be still too much creep-killing. Since you should target on last hitting while doing your lane.
