This is a guide for Viper Mid, he's a really good hero to play and he can take down enemies with a fell swoop. I usually go 18 - 3 - 6 with this guide, figured I would show you guys the method to my madness on this amazing character.

Start: You want to try to build up your resistance/HP regen early game as viper is quite squishy starting off. You want to harass your enemies with poison and GANK, GANK, GANK, GANK, GANK. Did I say you should gank? You should gank. Viper is excellent at ganking mainly because of his slowing power and his rate of fire. If in doubt, spam Poison (1) more.

Middle: By now viper should be able to witstand 1 v 2 fights (of course you're the 2 :P), and you want to get the rate of fire + damage on him up. I'll show this in the item build and I don't want to be repedetive so I'm just going to list what you should be doing at this point. Viper should keep on GANKING, even though by now he can probabally win a fight head on. It's still a neccesity to focus on strength if you're noticing an increase of deaths but you should mainly be focusing on agility and firing rate to get your DPS up. Again, if in doubt, spam Poison (1) more.

Ending: You've basically won the round (hopefully), and you want to finish this quick without a doubt of you winning or them making a comeback. You want to get your DPS up by mainly focusing on damage and fire rate. You should be mowing down your enemies literally within seconds. You should be using Viper Stike (4) on your enemies to get the jump on them then finishing them off by spamming Poison (1).

Spells: I don't want to go too far into detail with this, but it's simple. Get the jump on him with Viper Strike (4) and then spam Poison (1) untill he's very low at HP.

Please don't use this guide if you're playing anything other than mid, if you are going to use this guide under these circumstances then please don't downvote as this guide is for mid viper.
