Deathcap on AP Teemo as a second item?

I like to go Haunting Guise/Sorcs into Nashors, then Rabadon, i usually finish Liandries later in the game as it doesn't give that much for it's cost - just my 2 shrooms :D

death cap probably, bigger number damage, void staff good once they start stacking, either way most carries wont get alot of MR.

you can try lichbane first on teemo, it works quite well with an auto q auto for poke and makes him faster.

At that time of the game they won't be having very much MR and considering you already have liandries, it's doubtfull whether Voidstaff even does much.

Better solution: Don't play AP Teemo and make the world a better place.
