This guide is designed to combine damage + critical chance + attack speed, in that order. Because Spray and Pray is now 12 seconds or 5/6/7 shots, it is necessary to maximize the damage within those shots. Hence, the high critical chance.

abbreviation guide:
crit% = critical chance
HP = health points
AS = attack speed
ARP = armor penetration
MR = magic resistance

The Pros:
Stealth
Massive physical damage
Maximum attack speed
Multi-target damage
On-hit effects stack quickly
Fast movement speed
Decent early game harassment

The Cons:
Squishy, can be killed quickly
Oracle's Elixir or Vision Ward are very bad
Slow movement during early game
High priority target during team fights

I'm confident in my offensive skills. Defense is usually out of the question after early game anyway. If you are uncertain of your own, then I would suggest the following alternatives:

Greater Mark of Desolation Greater Seal of Vitality

I use Flash mainly because of its defensive qualities, i.e.: hit Ambush then Flash through a wall, getting out of range of AoE spells, dodging an ambush, etc. Survivability in an ambush or bad team fight is crucial. There's nothing wrong with living to fight another day. However it's also a great offensive spell. Tower-dives, pursuing near-dead enemies, or instant repositioning in a team fight.

I chose Exhaust because it slows and reduces damage on the target. It allows you to briefly pursue or escape a single opponent. You can also 1v1 a squishy physical opponent during early game to get that First Blood!

Since everyone's playing style is different, the order in which you acquire the items is not absolute. However, I highly recommend first building Mobility Boots. Second, build Infinity Edge prior to any other items. After which, you may then start with Zeal then finish Phantom Dancer. If the game draws out, build Sanguine Blade then Frozen Mallet, and Last Whisper

As you can see, there are no defensive items here, with the arguable exception of Frozen Mallet because of the HP boost. I rely on superior firepower to outmatch my opponents. However, there are some circumstances which might require defensive items, so don't hesitate to adjust according to the armor/magic qualities of the enemy team.

In a team fight, I cannot emphasize the importance of being patient during a team fight. Rely on your tanks and melee champions to engage the other team. Once they are preoccupied, seek out the other team's squishy champions and obliterate them. Be sure you prioritize the opponents appropriately so take out the hardest hitters first. Also, don't hesitate to flee from the battle if you find yourself being focused. Hit Ambush as soon as possible, find some bushes, something. Otherwise, once your squishy targets are taken care of, assist in the devastation of the remaining champions.

As far as skill rotation goes:




Expunge

If you're low on mana, or don't need to keep up with your target, don't use Venom Cask and just go straight to Expunge. When ganking, you probably won't need Spray and Pray either. But this is late in the game when you've become unstoppable.

Early game:
Twitch is a weak champion, so try to take mid then sneak up top to help. Otherwise go straight to the speed-boost, hit Ambush, and rush the top. Harass opponents until one is vulnerable. The best thing you can do is get in a few shots and wait before you use Expunge so Deadly Venom has time to tick off some HP. Once you hit level 6, start using Spray and Pray on your opponents to force them to retreat.

Mid game:
Between level 8 - 12, you might have a few kills already, and you probably have Infinity Edge and Zeal. You must constantly be on the go, neutralize or capture points, stay with your team during fights, meanwhile killing minions to bolster your cash flow.

Late game:
After you reach level 18, you should have a decent amount of kills and you're probably finished with your 4th item (including boots). Continue to kill minions between team fights

In a team fight, you will want to position yourself as far away from the melee as you can, while also in range of the squishy targets you intend to annihilate. In other words, you will want to be to the side of the melee. If you must flee, you will probably run sideways from battle instead of backwards. If you end up moving around in the battle, pay attention to location effects you might run through. The last thing you need is to take unnecessary damage, encouraging your opponents to switch their attention to you. Also remember, Spray and Pray affects multiple targets, so use Venom Cask, as needed, for some security while you're moving around. Once you have 1 or more targets at very low HP, pop Expunge to take them out.

I cannot stress the importance of patience and positioning in a team fight. It will make a huge difference between knocking over targets and getting yourself knocked out early in the fight. Wait for your targets to use their stuns, snares, or silences then make your move.

This guide is my first attempt at sharing my success with other players. I find this build to be highly successful. However, it is by no means guaranteed to be 100% effective. There are good games and bad games. That being said, most of my games finish with a positive kill/death ratio. Even in losing games, I usually always finish with a positive K/D ratio.

It is very easy with this build to get double and triple-kills, with some extra attention to detail it is not out of the ordinary to get quad-kills and penta-kills. But don't expect it, those are generally due to luck and good team work than skill.

This guide was originally inspired by a Twitch guide written by Xaioli. After testing different adaptions of other guides, it was this one that began my intrigue to develop my own.

I hope success and enjoyment find you while using this guide. My game name is miniondominus on US server. Happy shooting!
