INTRODUCTION This is ThatsNoTree, Welcome to my own take on an aggressive support Thresh build that leans on an aggressive start with stakkik shiv to get your late game support items. This build requires you to play an aggressive bot and keep the pressure on the adc and even though it deviates from meta with shiv. I have found it to be effective on Thresh combined with and his built in passive This is my first build so any constructive help with coding or the build overall would be appreciated.

Pros + Flay's passive (alongside its 200% AD ratio)combined with Damnation makes Thresh a very versatile support, being able to trade on some scales evenly with an adc. + Being able to initiate with Death Sentence and save or bring in gankers with Dark Passage. + Flay alongside damnation help him autoattack at a scary level trading with his high mana use. + Damnation can easily help you gain armor and ability power as long as you keep up with souls. + The shield on Dark Passage can act as an activated aegis late game, and helps in some trades between your adcs and a well timed The Box can land on an enemy champion.

Cons - With the latest patch you don't scale armor anymore so you're pretty squishy with little to no armor at the beginning until you start farming souls. - Mana Hungry if you rely on your abilities too much, an issue I hope to remedy in this guide. - Though you may bring utility late game, your damage in teamfights is really lacking. - An offtime The Box can be flashed over or tanked through if you use it wrong. - Can be gold hungry like most supports to finish his build, so pick up jungle and lane farm as the late game approaches.

Ignite: Is a situational spell for supports that I usually get when the adc picks up barrier, it helps to make up for the lack of damage in bot lane with barrier.

Exhaust: With a debuff on attack speed, attack damage, and movement speed this spell is seriously underrated. It works well with your long range autoattack and can help your adc trade with their debuffed adc better.

Flash: All around get the hell out of their spell that can easily help you make up the distance to Dark Passage your adc back to tower and get you in range of your Death Sentence.

Damnation: Thresh's passive allows him to collect souls to gain ability power and armor(eventually makes him tanky), but trades off with the notion that he no longer scales armor per level.
Death Sentence: Death Sentence allows you to grab an enemy champion and drag them slowly towards you for 1.5 seconds. He can activate again to pull himself to the enemy champion, gaining a 3 second cooldown on hit. Should be used wisely as it can deplete your mana at hand pretty fast, so save it for a sure on hit or during a duel.
Dark Passage:Dark Passage allows Thresh to throw out a lantern for an ally player to catch. Any champions in the lantern area get a shield and on click of the lantern move them to Thresh's location.
Flay: On Passive Flay deals bonus magic damage equal to a percent of your ad plus the amount of souls collected. On activation Flay pushes or pulls the enemy champion depending on direction and slows them for a duration.
The Box: The box slows and damages any champion that collides with any of the walls and champions hitting more than one wall take half the damage and half the slow.

Statikk Shiv: First lets look at the stats of Statikk Shiv; 40 attack speed, 20 critical strike chance, 6 movement speed multiplier. Along with a Unique Passive: At 100 charges your next attack expends the charges to deal 100 magic damage to 4 targets with a crit chance.

Flay: Secondly lets look at the passive on Flay; Thresh deals bonus magic damage on each auto attack. The damage is equal to the number of souls collected plus 80/110/140/170/200% of attack damage,based on length of time since last attack.

IN CONCLUSION: If you couple these two passives together(they charge about the same time), on your first attack you'd deal up to 200% percent of attack damage+souls collected+100 magic damage(over 4 targets)+ a crit!

9 OFFENSE 21 into Defense

The 21 points in defense is a must for my build, you need the defense masteries to make up for the lack of armor you have at the beginning of the game. Most of the time you don't the extra magic resist in bot lane so I usually take only one point in it, though I suggest changing that if they have an annie support. Q: Why take offensive and not utility? Though questionable, I have tried utility vs offensive masteries for the remaining 9 and found that if you don't rely on your abilites and spam them to land one death sentence. You tend to not be too mana hungry using the occasional ability, while having the 9 in offense gives you a much better ad ratio to proc in your flay in the early game.

This is my first guide, the keywords there being "guide" so please don't consider my build an every situation build as it isn't. Of course feel free to give constructive criticism and if you choose to downvote let me know why and not just downvote. I hope this helps you develop a different playstyle with Thresh and the guide is in progress so I will be adding match ups and item explanations and screen shots later. Other than that thank you for taking the time to read my guide and good luck with charging the SHIV!
