• The first soul will grant 1 bonus ability power and armor. Subsequent souls will grant 0.005 less, down to a minimum of 0.5 per stack. Souls cap at 999999. ^[1]
  • The 0.5 minimum is reached at 101 stacks, granting 75.75 bonus stats.
  • The maximum amount of ability power and armor gained is 500,024.75.
    • This amount of armor, including his base of 18, grants 99.98% damage reduction.
      • Even with the 35% armor penetration from Last Whisper, Thresh still benefits from 99.96% damage reduction.
    • Thresh surpasses 99% damage reduction at ~20,000 souls, rendering souls above this surplus with regards to armor.
• It takes 49-94 souls to catch up to the armor levels of other level 18 champions (61 to 90 armor, including his base armor).
  • At 95, Thresh has the highest innate armor not including other champion's abilities.
  • It takes 146 souls to match a level 18 Taric with rank-5  Shatter - the highest armor available without items, runes and masteries (116 armor).
• At 255 souls, Thresh gains a new buff, "Soul Gluttony". Soul Gluttony states that he has gained 255 souls as well as how much ability power and armor that is worth. The Damnation buff disappears, and starts again at 1 from your next soul. This will occur each time Thresh obtains 255 souls, with Soul Gluttony updating each time (e.g. 255, 510, 765, etc).
  • The full description of Damnation will list the total number of souls, armor and ability power. For example, Damnation may show "1" stack but will state "256" in the full description.
• Souls spawn within a range of 1900 units. ^[2]
  • On Summoner's Rift, the drop rate for souls from small minions is 33%. However, the probability adjusts dynamically. If you are above or below your expected quota of soul drops from small minions, the probability lowers or rises by a small amount until you are back at your quota of drops ^[3]
    • It is worth stressing that this only takes into account souls dropped, and not souls collected.
  • The souls disappear after about 15 seconds.
  • Souls are visible to your allies at all times. If an enemy can see Thresh when the soul is spawned or at some point during the soul's existence, the soul becomes visible to the enemy team for the remainder of its existence.
  • Souls are colored differently depending on the team Thresh is on.
  • Souls look significantly smaller for both Thresh's allies and his enemies than they look for him
  • It is currently possible to collect souls while dead. It is unclear if this is a bug.

• Death Sentence procs spell vamp and Rylai's slow similarly with all single target spells and abilities with full effect.
• Death Sentence pops Spell Shield.
• Death Sentence will damage  Black Shield and its disabling effects will be negated.
• On impact, Thresh will immediately pull the target for ~300 distance towards over 0.25 seconds. 0.5 seconds thereafter, it will again pull the target another ~300 distance towards him for over 0.25 seconds.
  • The target can be pulled past Thresh and through thin walls and temporary terrain if the target is close enough.
• Death Sentence can be used to dash over walls if Thresh reactivates the ability to pull himself toward the target.
• Thresh can move while pulling his target, changing the direction of the pull.
  • Thresh cannot autoattack until he either reactivates the ability or the duration of the grab ends.
• If the target dies after the contact of the scythe (by either the initial magic damage or other source of damage), the scythe is immediately retrieved, that means Thresh can no longer pull himself to the target.
• Even if Death Sentence's stun is removed (e.g. with Cleanse), the scythe is still attached on the target. That means Thresh can still pull himself to the target's position regardless and cannot autoattack until the scythe is retrieved.
• Bot Champions will attempt to use Cleanse after being hit by the scythe.
• If Thresh is inflicted with any ability-restricting crowd control effect after the scythe has hit a surviving enemy, Thresh cannot pull himself unless he removes the ailment on himself before the scythe is automatically retrieved.

• The lantern provides vision in a small area for the entire duration.
• Dark Passage can be used by allies to dash over walls.
• Thresh cannot click on the lantern himself.
• Dark Passage can be used to collect souls for  Damnation. However its range in doing so is smaller than Thresh's range.
• Thresh can break the leash range to instantly shield himself, if he has not been shielded by the ability already.
  • This will cause Thresh to practically "have" the lantern for the rest of the actual duration; this means, if the tether broke, Thresh can move to an allied champion and shield him, if the ally has not been shielded by the ability already
• Katarina's  Shunpo, Lee Sin's  Safeguard, and Jax's  Leap Strike can be used on the lantern.
• Allied champions can Teleport to Thresh's lantern. If the lantern's duration expires, the teleport will still continue to the lantern's previous location.

• The passive will accumulate some bonus damage during the wind-up of each attack.
  • This means that further away targets will take slightly more damage than closer targets in a persistent auto-attack fight, although for the most part the difference is less than 10 magic damage.
  • The time it takes for the passive damage to fully charge is currently ~10 seconds.
• The percentage of his attack damage, based on the amount of time since his last attack is accumulated linearly.
  • This means that the % AD-based damage of his Flay passive does not benefit from attack speed.
• Both the soul-based and attack damage-based damage of Flay are applied to the minor bolts from Runaan's Hurricane.
  • However, each time Thresh's autoattack or a bolt lands it resets the amount of time since Thresh's last auto attack. This means that the % AD-based damage of his Flay only adds a negligible amount of damage to the bolts from Runaan's Hurricane.
• Flay's on-hit damage will not pop spell shield.
• Flay's on-hit damage will damage  Black Shield.
• Flay's on-hit damage is not applied or consumed while attacking structures or wards.
• The buff icon of Flay namely "Shackle" will appear on Thresh's status bar once he has learned this skill. The color of this icon indicates how much percentage the passive has charged, from green (>0%) to yellow to orange to red (100%).
  • When Thresh has successfully made an autoattack to the target, the icon will be briefly disappearing, denoting no bonus damage is granted by the passive for the time being.
  • When fully charged, Thresh scythe will visually glow in green. A distinctive gloomy slash sound effect can also be heard.

When activated, Flay is an point blank line area of effect ability that deals magic damage to enemy units in a linear area in front and behind Thresh. Enemy units hit will be knocked in the direction the ability was cast and they will be slowed for 1.5 seconds. For example, casting the ability behind Thresh will cause all enemies in front of him to be pulled toward him and enemies behind him will be pushed further back. Inversely, casting the ability in front of Thresh will cause enemies behind him to be pulled toward him and enemies in front of him to be pushed away.

• Flay procs spell vamp and Rylai's slow similarly with all area of effect spells and abilities with diminished effect.
• Flay pops Spell Shield.
• Flay will damage  Black Shield and the slow and knockback/pull will be negated.

• Note that movement speed cannot be reduced below 110, and that slows that would reduce below 220 are modified. To put it another way: a reduction of 99% will not reduce you to 3 movement speed, but rather it will reduce you closer to 110 than a weaker slow would.
  • Without slow resist from Relentless or Boots of Swiftness your movement speed will be between 110 and 120.
• The Box procs Rylai's slow similarly with all area of effect abilities with diminished effect. PENDING FOR TEST
• If a champion with a spell shield walks through a wall, the shield is popped and the wall will shatter.
• The Box will damage  Black Shield and the slow will be negated. The wall will be destroyed in any case.
• Activating The Box creates the 5 walls around Thresh's current position, forming a closed pentagon which points to the bottom of the screen.
• The 1st wall deal the full 250 / 400 / 550 (+1.0 per ability power) and 2 seconds slow.
  • All subsequent walls do 125 / 200 / 275 (+0.5 per ability power) damage and a 1 second slow.
