(WARNING i have only used this build when going mid so i can not guarantee full effect on other lanes)

Alright so here is my build which i have used for quite a while now and i have not yet lost when using it so i though that i might post it.

Summoner spells

ignite and explosive shot deals massive dmg and is great when killing runners

flash great to use to get behind enemys so that you can blast them into turrents/team mates with buster shot

Alright let's start of with lantern,

why? well first of there is the life steal which is amazing when playing tristi thanks to her explosive shot

also it has a chance to deal 500 dmg to a minion, again great with her explosive shot

Then there is the Free ward supplied with lantern great to use when opponents are getting hot for that gank and in late game you can ward baron (yay)

berserkers for the speed and the movement (duh)

Guinsoo's for the speed stacks, but Church why get a item That involves AP when none of the others are? well i do not go for the AP in the item but it can still be of great help early game when using the (ignite+explosive shot+buster shot) combo.

Infinity edge: The massive dmg that Infinity gives along with guinsoo stacks and rapid fire to deal massive dps

Phantom dancer (should be self-explanatory)

Frozen mallet for health and slowing down runners

speed marks to give her her amazing dps

Critical seals seeing how your speed will be very high which gives a very high chance to crit very often

Cooldown glyphs Great for escaping with rocket jump and to be able to use rapid fire to bring down towers and farm creeps faster by being able activate it more often

If you find my build to be **** then please tell me along with pointing out what might be better or what is wrong

-thanks
