THIS GUIDE IS BY NO MEANS COMPLETE, AS I LEARN MORE ABOUT THRESH, MORE WILL BE ADDED

Your passive is basically, dead things drop souls, souls when collected grant bonus armor and AP

You're Q is pretty simple, throw a hook, hook attaches to whatever enemy it first lands upon, deals a lil' bit of damage, and press q again to dash to the enemy.

W is a bit more complex. You throw down a lantern, any ally can right click it to dash to you. Any ally that walks over it is granted a shield, along with you. It can be teleported on and collect souls...lots of neato things you can do

Your E....How should I explain this....E is a displacement spell, knocking enemies back or forward depending on where they are in relation to the hook and are dealt a bit of damage. (Guys in the front are knocked forward, guys in the back are knocked backward)

R spawns a pentagonal wall around you, with enemies who walk through the sides are dealt a nice chunk of damage and slowed

DON'T CS
While it might sound stupid, but to be a good Thresh, you just need to pickup your coins, souls, and land those hooks. I except you should have at most 2 CS at 10 min.

Otherwise, predict where the enemy is gonna go. If they're low on health and your jungler/ADC is coming towards them, they're gonna use whatever escape mechanism they have, whether it be a Flash, or Tristana W, which by the way can be intercepted by your hook, anyways, they're gonna run and when they do HOOK EM!

Mid Game, vow up with your ADC and in teamfights HOOK EM. Use W to save teammates in sticky situations, and E to stop people from running. R for the slow and nice bit of damage if you happen to land in the middle of a bunch of enemies when you take the second part of the Q (more to come in the combos section).

Pop off your hooks, use Redemption to save your teammates, and do most of the Mid Game stuff. Also, as you should have acquired a decent chunk of HP and armor by now, you can help tank and protect your carries.

Q,W,Q,E,R

Very simple, once you land hook, throw down your lantern, press your Q again to dash to your enemy, and if your ADC/whoever is smart, they should click the lantern and come with you. Once you arrived at your new best friend, press E to knock them back, and R to make sure they ain't going nowhere.

WARD WARD WARD

After your first back, you generally want to switch over to the sweeper to limit your enemy bot lane vision. And of course buy a contorl ward, which is a good habit to start keeping. Your gold item will provide you with 4 FREE wards which helps you not get ganked.
