Hey everyone!
This is my first guide so please don't cry about everything. I tried it a few games and it worked everytime! In the lategame no one was able to kill me because of my heavy damage and high health.

Farming: Farming with Thresh is very easy, because the q will help u too lasthit the minions.
If big minon groups reach your tower use your e to kill them.
Getting ganked: if you're getting ganked just walk away and hook the enemie that will slow them
and u can walk back in safety to youre tower. If that didnt worked e them away.
Youre Jungler ganks:Hook the enemie and knock them to youreself so that the jungler
can gank easy.
Important:If you can't get a soul throw your lantern to get them! It's okay
to miss 1 or 2 but you wont get enogh armor without the souls and thay give you high ap.

Sorcerer's Shoes: Well you know, magic penetration ;D
Rod of Ages: Gives high hp/mp and allows you to stay much locnger on your lane.
Will of the Ancients: Gives you spell vamp and high ap. Also helpfull for your teammates.
Wit's End: It workes perfect with the passive of your q and gives you more attack speed
damaging unranged champions on your lane.
Rylai's Crystal Scepter: Gives you ap/hp and a fat slow (that will help your
team roo)

Abysaale Scepter: It gevis you migic protection, ap and magic penetration (you could need the
magic def because you won't gain magic def from your passive)
Lich Bane: High normal attack damage after a spell.
Rabadon's Deathcap: Gives you a high ap burst.

"Damnation" is Thresh passive. It allows him 2 pick up greens balls which summon out of killed minions and champions. Thresh gains Armor and AP for every green ball he picks up. If you farm many balls you will have enough armor without even buying any item with armor.

"Death sentence" is the 1st spell you max. The reason is not the dmg output you have while using it. You max the skill first because of the passive. It allows you to do massive dmg with your autohits.
Also you can use this spell for pulling enemy towards you or moving to them. This makes it easy 2 escape ganks.

"Dark passage" This spell protects you or members of your team from incoming damage and allows them 2 travel towards you by clicking the lamp you placed.
this spell is very useful. It can help your jungle to gank your lane or team members 2 get out of bad situations without using flash.#


"Flay" can be used to throw your enemies away, or to hold them back for youre team.


"The Box". It does tons of damage and slows enemies down. If you use your ultimate after using "Death sentence" your enemy can only escape with flash. Using you ultimate while ganks you have almost a 100% chance to kill your enemy in toplane.

Pros: -hard to get ganked Cons: -he moves slowly
-Strong Abilities -bad skin :(
-heavy auto attack damage
-gains armor/ap per soul (passive)
