Disclaimer: This is not a normal Kha'Zix build, Attempting to play like a normal Kha'Zix will probably result in you & your team not having a good time.

When someone decides to chase you, they're giving you a lot of control over their movement and attention. So naturally, for this reason, the only time someone will chase you is when they believe there is minimal risk to doing so.

However, once we get an enemies attention and if we can hold it, we can prevent them from realizing the risk they are putting themselves or their teammates into by chasing you. This is the core principal that allows this playstyle & build to function, that's what we're optimizing for.

I've tried making this playstyle work on lots of other champions, but none of them have worked nearly as well as Kha'Zix for me. Here's a few champions and the reasons why I think that is:

• Singed: He's just too much of a threat, and therefore won't get chased very often because it's too risky. He also has limited options for movement, and therefore limited options for manipulating enemy movement.
  
• Shaco: The biggest issue with Shaco, is that you can't reliably hold the enemies attention. Using Q gives the enemy a great opportunity to focus their attention elsewhere and reevaluate if chasing you is worth it.
  
• LeBlanc: LeBlanc is the only one with comparable movement options, but they lose a lot of value once your up against multiple people, forcing you to disengage and therefore, lose the attention of the enemies.

By rotating Evolved W & Evolved E, Kha'Zix is able to both keep lots of movement options open and keep the enemies attention. On top of that, his ult can give you even more options, allowing you to deal with surprises. This combination of abilities, allows you to capture an entire teams attention, and keep it for extended periods of time all by yourself.

While we're here, the reason I don't play this top instead of jungle is that the jungler needs to be at the epic monster objectives, not getting people to chase them halfway across the map.

General:
One of my favorite things about this build is that you can execute this strategy even when you or your team is way behind, it doesn't matter how fed the enemy is if they can't catch you.

This is good because Kha's laning phase isn't particularly great, in fact, trading in lane is almost never really worth it, so just focus on getting farm, and not dying. The not dying part should be quite easy too, you're very difficult to Gank, Dive or force any kind of big exchange with your E W & R. (It's kinda nice when the enemy does try to camp me, because that means they aren't really accomplishing anything useful.)

If you do happen to get a big lead, enemies won't want to chase you anyway so, just abandon this build/playstyle and just do a normal Assassin Kha'Zix build and snowball out of control.

You also aren't really a great lane for your jungler to gank either, a lot of top laners can and will 2v1 you, and the accasional kill you'll get won't be super impactful. So I usually outright tell my junglers not to gank me. Or if there is a good opportunity for a kill, it's usually better to let the jungler take it.

Trading & Farming:
Farming can be a bit rough early, so just get what you can with W Q, AAs, and Minion Demat.

Once you hit level 7 and get at least 3 long-swords, you're trading/farming pattern changes, since now E + W can kill casters. And if the enemy is standing near them, E + W the casters, then Q them, and phase-rush out. *Only one of the W's missiles will hit the minions, so try to aim the others at the enemy.

There's 3 main components to executing the "get chased" part of this playstyle effectively:

• Getting the enemy to start chasing you: Split Pushing and invading are the main ways to accomplish this. Remember you want the enemy to collapse on you so position much more aggressively than you would on standard split pushers.
  
• Extending chases: Once the enemy collapses on you, don't just escape immediately, Take lines that give the enemy some hope of catching you. If they start to lose interest, stop running away & let them catch up. Or when they try to leave follow them spamming W for slows.
  
• Communication: The ideal scenario is one where the enemy team starts collapsing on you, just before your team starts pressuring an objective. You'll need to communicate with your team in order to make these things happen.

These can be applied to a variety of situations so let's look at some examples:


Scenario 1: Epic Monster Objectives (Baron/Dragon)

In this case your goal is to create an opportunity for your team to "sneak" a Baron or Dragon. In order to create this opportunity, you need to get the attention of the enemy team, ideally that of the enemy jg and the strongest member(s) of the enemy team, getting them to chase you away from the objective. Hopefully it goes something like this:

1. Invade the enemy jg with the intent of finding them
   
2. Once you find them get them to chase you. (Ideally this should be done before they realize that your team is making a play for an objective.)
   
3. (Optional) Start running away, except go towards the strongest member of the enemy team, giving them the opportunity to cut you off, and thus engaging them in the chase.
   
4. Begin running away from the desired objective, while keeping the enemies engaged. (By this point your team should be nearly starting the objective)

If everything goes well, the enemy should be too out of position to meaningfully contest the objective. It will probably take a good bit of practice and communication to get the timing down, I still haven't mastered it myself. However, if you can pull it off, it can be a great way to come back from a losing game.


Scenario 2: Your team has died

Given your ability to run away very effectively, you'll often survive losing team-fights, in which case you'll usually want to try preventing the enemy from making progress on objectives, so if the enemy feels like chasing you once they've won a fight, let them, you can stall for respawns, preventing the enemy from making real progress on towers and objectives.


Scenario 3: Dealing with Sieges

In this case, your team is probably not currently able to defend (probably due to death or something). So you want to stall and split the enemy team up. Sometimes what you can do is get behind the enemy and cut off the minion supply. Hopefully forcing the enemy to stop the siege and chase you, or at the very least slow them down.


There's still going to be lots of times where you won't be able to execute on this type of "get chased" strategy. In these cases it's usually best to first act as a support, using your mobility & slows to provide both peel and catch potential; and then as a relatively normal Kha'Zix, just with less damage.
