Most of time i use this boots because increase amount of damage.
Says it all litte bit of magic pen and ton of atk speed.
With this and your atk speed boots you should have endgame 1.6 atk speed which is very nice
for Teemo. With the new patch this item became even stronger on teemo its a almost must now
What can i say this item makes Teemo op on 3vs3 the 5% max hp burn is so stronk realy and magic pen and cd reduction this ITEM IS MUST FOR TEEMO.
This item just mandatory on any ap carry on 3vs3 plus this item is op rabadon and hour glass in 1 item yes plz.
When you have above items you can choose what you want more sustain buy rylai enemy has high mr buy a void staff.
why rylai on Teemo it slow on his basic atks and on q and has just good ap and health.
I personaly dont like this item very much i dont say its bad item but milady gives the mr shred and is lot faster to build then nashertooth.
It just delays your build alot because it cost alot it has very good stats for teemo 100% but it just takes very long time to finish and you need your blackfire torch asap.
If you want and you have cash lying around everywhere you can switch endgame milady for nashertooth if you like it more.
