Hi guys whose like support-tanky champions. Treshis stunter support so you can play him as tank too. He is better if he is going with DPS carry like(on bottom lane) : Caitlyn,Vayne,Draven,Ezreal,Twitch or Fiora. He is not good on middle lane. He is too ok with AP carry like :
Katarina,Ryzeand sometimes with Nidalee.

Pros



+ Very hard CC
+ Death Sentence's passive, along with the passive soul-grabbing, nets him very good free AP and a sweet auto-attack damage.
+ Is both a great life saver as he is a great initiator
+Extremely tanky early game, able to easily take harass and/or focus while your ADC gets many kills. And, most importantly, negates the early handicap that the lack of additive passive armor gives Thresh
+Your Dark Passage, while commonly used only for the utility, will now be perfectly and greatly used for its shield, literally doubling its usefulness and making sure your lane is gank and damage-proof.


Cons


- Dark Passage's shield is pretty much useless if not focused first and other players do not know how to use the teleport to lantern.
- His spells cost much mana.
- Starts with little to no armor and very squish thanks to Damnation, unless starting out tanky (That's why you're reading this, most likely)
-The Box is easily flashed over / tanked through.
-You won't deal enough damage to get kills / make the difference on teamfights, so your gold will be very slow-coming in case you do reach mid-late game.

Exhaust
It'll help you kill or help many times,, as you and your ad carry can usually catch up to him even after he flashed. It also helps control teamfights and traps. It's a perfect spell for any supports.
Flash
It's good spell if you must escape from stronger enemies. If you use The boxand you have not much health you can use flash to get escape.

DARIUSHe is very stronger,armored OP so don´t go solo vs. him.
If you like to be alive do NOT use Death Sentenceon him.Communicate is stronger weapon to him.
CaitlynShe is OP too,but she is CARRY.On first game try to gank/farm her.On mid game she can kill you easly if you don´t have much armor.On last game try to have health and more armor because she can use Ace in the holeand you will be death if she has full build. Using Death sence and flay is good way to kill her
EliseShe is stronger because she can stun you and she deals a lot of damage.I know she is always on middle lane, but when is she jungling she can catch you in her trap.Two abilities doing percental damage (Neurotoxin / Venomous Bite).She can use it easly if she stuns you with cocoon.Try to playing very defensive may be a problem for her. Use Dark passage for reduce damage to you.

I thank you to see my build. I'm still sorry for my English, please do not downvote just because of my English.So i will say only this : Good luck and have fun with Thresh the Chain Warden or Thresh the Warden of your Chain :D.
