AP Burn Thresh Build

General

1. You play as Mage building Burn items.
2. You rush Liandry's Torment.
3. You burn your enemies. With DOTs. And debuffs.

General

1. Playing AP Burn Thresh build, your default rush is Liandry's Torment vs. HP, Blackfire Torch vs. squishes. Then get the other item.
2. Adapt to an enemy team. Are they full of tanks, and they rush tons of Magic Resist? You rush Void Staff as #2 or #3 item to counter MR stacking. Their team has champs with lots of healing? Rush Oblivion Orb as #2 item (upgrade to Morellonomicon as 4th or 5th item).
3. Items like Morellonomicon or Oblivon Orb are extra effective with this build, thanks to damage over time effects from Liandry's Torment.
4. An enemy team has an extremely strong shielding? You can get Serpent's Fang to counter it. It works with your DoTs, meaning shield reduction lasts longer.
5. Somebody is going after you each fight? Always getting ulted by enemy assassins? Rush Zhonya's Hourglass.
6. If you are doing well, are ahead and want to have some fun, you can buy The Collector item. It works off your damage over time effects!

Champion

1. You primarily will be looking to hit Death Sentence (Q). Once you do that, you can (go in), use The Box (R), use Flay (E) and follow that up with auto attacks. Or just do it from the distance, use E, maybe R and a couple of auto attacks.
2. You can use Flay (E) during Death Sentence (Q) flight. That's a very cool interaction that will let you do some plays and more damage.

General

1. Flash + Flay (E) is often better than Flash + Death Sentence (Q) - E first then land guaranteed Q as they try running away while slowed.
2. You are a CC machine and it is important that you coordinate CC with your team. Hook after ally CC for guaranteed hit, or save hook to extend their CC duration.
3. If you are playing against any Spell Shields, try getting rid of them before engaging. Either wait them out or fake your abilities, so they wasite it.

Death Sentence (Q)

1. Remember that if you reactivate your Death Sentence (Q), you commit to it, good or bad. Make sure it is worth it and it is not one way ticket.
2. Sometimes it is better to let your team collapse on the target or just leave it be - for poke and zoning.
3. You don't always want to reactivate Q immediately. If you wait for full duration, you will drag enemy a little bit closer. As well as you can chain it with Flay (E) for longer CC.
4. You can use Death Sentence (Q) to escape. Just Q to a minion or enemy champion that is far away.
5. Hook through dying minions - time your Q to pass through a minion as it dies to surprise enemies hiding behind wave.

Dark Passage (W)

1. You can fake lantern to help your allies or to play mind games. Throw Dark Passage (W) back without anyone to make enemies retreat thinking backup arrived
2. Flash while ally clicks Dark Passage (W) to pull them to your new location for extended range escapes, engages or some cool plays.
3. You can use Dark Passage (W) for scouting bushes.
4. Use lantern on souls to collect them safely from distance without face checking.

Flay (E)

1. Flay (E) cancels dashes and channels - keep it and time it to interrupt enemy jumps, channels etc.
2. Flay (E) backwards first to slow enemy, then follow with Q for near-guaranteed hook on slowed target.
3. Flay mid-air during Death Sentence (Q) dash - cast Flay (E) while flying to your hooked target for instant additional CC.

The Box (R)

1. The Box (R) is very versatile ability. You can use it both offensively and defensively.
2. You can use The Box (R) for disengage and stopping enemy team engages.
3. You can use The Box (R) for peeling from your allies. Enemy assassins going after your carries? Put The Box (R) down and watch them go around or thorough it, getting slowed in the process.
4. Offensively, The Box (R) can be used to trap enemies, cut off their escape, or initiate fights alongside your team.

Thresh Combos

1. Hook Flash Lantern combo - Death Sentence (Q) enemy, Flash toward tower/team, then Dark Passage (W) your ally in for extended engage range.

Riot

1. Communication is key when making use of Thresh's lantern. Let your teammates know how you like to use it.
2. Death Sentence and Flay can be combined in either cast order for powerful combinations.
3. Thresh can collect souls without needing to kill units himself. Planning your map position to be near the most deaths will help to maximize soul collection.
