I tried this build out in a Practice game and i liked it so i figured i would put it on here.

i started with the fendish codex to get some mana regen so i could spam the dart and keep a decent mana ammount for shrooms and such. then i got the berserkers greaves because i would need some attack speed seeing as this build is not heavily based on attack speed. i finished the nashors tooth once again for attack speed and the cd reduction, mana regen, and AP.

Then i got the hextech revolver to build into the hextech gunblade so i could have some lifesteal, spell vamp, and some attack damage with ability power. i got the guinsoo's rageblade once again for the ability power and attack damage. its also good because of the stacking ability which gives you more AD, AP, and attack speed while attacking (max 8 stacks).

I got the lich bane for the ability power, and mana. i especially got it for the passive, i find that this passive works great when you shoot the dart then follow up with a basic attack, does some nice damage. i finished up with the rabadons deathcap because it adds 155 ap and 30% additional AP. this is very helpful because it makes your dart, poison, and shrooms do even more damage.

The two other builds here are Solid AD and AP. the first one is AD the second is AP.

These are the build i normally use in games (i change depending on the # of ap/ad champs on my team). I figured id throw them out there for you to see.

If any questions please ask, Rate and comment.

thanks
