Laning on thresh is the main area you can look for leads and abuse the enemy as much as possible, this is on of Thresh's main strengths, and enables his team to play from ahead from an early point in the game.

As soon as you get to lane make sure you track the enemy jungler, and see what side of the map they are starting on. If the enemy jungler starts on bottom side, and is a jungler that can easily gank level two, such as Twitch or Xin Zhao, then look to keep the wave frozen and not to look for an engage too fast.

Do not use your first 2 minion kills for your support item on the first wave, but instead wait for the second. Once the second wave's collide, do your best to push the first 3 warrior minions and get level 2 before the enemy does.

Once you have done this you will do your standard play of walking up to them and flaying them towards you, then auto attacking them once, then hooking them after. This is an optimal engage as you do lots of damage and CC them for a long period of time.

Most opponents will back off before you hit level two so don't worry if you don't get an early kill.

After the level two, your level's 2-5 will all be the same, using the pressure of your hook or flay to push them back, allowing your ADC to push the wave if they can, or freeze to deny minions.

Once your wave is pushed in look mid to see if you can roam, you can roam mid if: Your mid laner is strong, the enemy mid is pushing in, or if your jungler is also looking mid. If none of these, simply walk into the enemy jungle and place a deep ward by their raptors, or their gromp if you are blue side.

Keep going bot to catch big waves and relieve pressure for your ADC while also looking for hooks on the enemy ADC or Support. Prioritize the ADC over the support, unless the support is playing something like Sona, Soraka or Nami, or any super squishy support.

Once you hit 6 you can continue looking for roams as normal, however now you can be much more aggressive due to your increase in damage and CC.

Note: It is perfectly normal and fine for you to have much less EXP than your ADC, so if you see your 1 or 2 levels behind do not worry.

Mid game as thresh is another really strong point, as Thresh can move around the map with the jungler and make plays happen. At this point in the game your ADC is your second priority, as you just want to help the team as best you can, rather than just one player.

You can leave your ADC and treat them as you would your mid laner. Constantly seek to destroy enemy wards, and ward up areas around dragon and baron/herald, depending on what your team wants next.

Use this vision advantage to look for kills or picks, or sometimes even to sneak away with a dragon or something.

Use your lantern to keep teamates safe, and look to hover around mid, and whatever lane the next objective is next to, such as both for dragon. Try to get EXP here and there but leave champs that need solo EXP to get it themselves, such as kassadin.

Make sure to base at least 40 seconds before an objective so restock on wards ETC.

Not often will you get to late game on Thresh, however if you do, your main goal is to constantly keep the enemy off your squishy targets, or to hook important enemy's such as a lux etc.

Make sure to keep constant vision on objectives, and look to get your wardstone to help do so.

Other than that is plays largely like the mid game, just with some added protection to your carries.

Tip 1: Make sure to keep flay if they have a champion that uses dashes. Important champs are: Rengar, Tristana and Zac. You can flash Zac out of his E when he engages, you can flay rengar out of a pounce, and you can interupt tristana's rocket jump to secure kills on her. Other champs have simelar abilities also so keep an eye out.

Tip 2: Be careful with taking hooks in, usually if your team has any other engage you don't need to follow the hook, and can just stay with your back line.

Tip 3: You can cast R while using Q to ensure you hit them with it.

Tip 4: When playing against Ezreal or Kassadin, remember to try and predict where they will blink to once you use Q, as your Q is very easy to see once its being cast.
