The modifier {{c|mod|#% of Life Leech applies to enemies as Chaos Damage}} takes 200% of the actual life gained from [[leech]] and deals it as [[chaos damage]] to enemy that was the target of the leeching. Therefore, by default no damage is dealt if the player is at full health while leeching. This damage is not affected by damage modifiers as it is considered as [[reflect]]ed damage.<ref name="RetchDMG"/>
{{c|mod|#% of Life Leech applies to enemies as Chaos Damage}}: this modifier causes hits to apply chaos DoT with a DPS and duration based on the recovery and duration of that hit's life [[leech]].
With [[Ghost Reaver]] modifier the damage is dealt based on [[energy shield]] gained from leech.
The Retch's DoT is independent of player recovery: hits will inflict it even if the player is on full life and loses their leech immediately, or when the player is unable to recover life due to {{psl|Strength of Blood}}. Increases to player recovery, such as {{c|mod|% increased Recovery Rate of Life}} or the more specific {{c|mod|% increased total Recovery per second from Life Leech}} do not affect the Retch’s damage.
Because the DoT is considered reflected damage<ref name="RetchDMG"/>, it is not modified by the attacker’s offensive stats, only by stats on the enemy. Its duration can be extended by {{il|Temporal Chains}}, dealing the same DPS for a longer duration. Each instance of the DoT can deal damage; damage taken is unaffected by the per-second cap on recovery from leech<ref name="RetchCap"/>.
{{psl|Ghost Reaver}} disables this mod completely. The Retch cannot deal damage in areas with {{c|mod|Cannot Leech from Monsters}}, or against monsters with {{c|mod|Life Cannot Be Leeched}}. It has no interaction with {{c|mod|Damage Taken from Hits is Leeched as Life}}.
This modifier can be increased by Noxious and Fertile [[catalyst]]s, up to 240%.
This mod can be affected by the quality from {{il|Noxious Catalyst}}.
===Instant leech===
===Instant leech===
Instant life leech modifiers (such as {{il|Bloodseeker}} or [[Leech Mastery]]) cause the chaos damage derived from instant leech to be dealt instantly as a hit, rather than as damage over time. This damage can be mitigated by modifiers to damage reduction from hits, such as {{il|The Fourth Vow}}. The damage dealt is based on the amount of life possible to be recovered from instant leech before the character reaches full life.
==="Life leech is not removed"===
Instant life leech modifiers (such as {{il|Bloodseeker}} or [[Leech Mastery]]) cause this modifier to [[hit]], dealing damage instantly. This can cause the damage to be mitigated differently, for example through {{c|mod|chance to Avoid All Damage from Hits}} or by exiles wearing {{il|The Fourth Vow}}. Instant leech does not result in more total damage, as the Retch’s DoT can stack indefinitely.
With {{psl|Brutal Fervour}} or other sources preventing leech from being removed, the damage will continue as long as the leech instance persists, even at full life.<ref name="EndlessHunger"/> If a player has both instant leech and overleech, the damage is derived from the full potential recovery of the instant leech (rather than the amount recovered), even at full life.<ref name="EndlessHungerVaalPact"/><ref name="EndlessHungerVaalPact2"/>
===Interaction with proxies===
Skills used by [[totem]]s, [[trap]]s, [[mine]]s, [[mirage]]s, and other [[proxies]] can inflict Retch DoT in the same way as the player. This uses the player’s stats for all calculations, including maximum life.<ref>https://www.youtube.com/watch?v=NdZRdQ9cO1w</ref> Because dead objects cannot leech, traps and mines can only leech before finishing their trigger/detonation animation.
Kills by Retch DoT from non-player objects are not attributed to the player, unlike most other forms of damage over time. When Retch DoT from no longer existing objects causes monsters to die, those monsters do not grant experience or flask charges, and their loot is unaffected by player item quantity and rarity<ref>https://www.pathofexile.com/forum/view-thread/3401772</ref>.
===Scaling===
===Scaling===
The only bottleneck stat relevant to The Retch's damage output is {{c|mod|Maximum recovery per Life Leech}}. This establishes an upper bound on how much life recovery a single instance of leech can have - regardless of whether it is instant or not. The Retch causes damage equal to a percentage of the life leeched by each leech instance, so this cap also limits the amount of damage The Retch can do for each leech instance.<ref name="Retch Instant Leech">{{cite web
The Retch's base damage is bottlenecked by {{c|mod|Maximum recovery per Life Leech}}, normally 10% of the player’s maximum life, whether it’s instant or not.<ref name="Retch Instant Leech">{{cite web

}}</ref> Therefore, in order to increase the damage of the Retch, the player has to either increase the cap of Maximum recovery per Life Leech (while still reaching said cap), increase the players life pool, increase hit rate (more leech instances) and/or increase damage taken of the enemy (e.g. curses). Any type of direct modifiers to damage dealt (e.g. {{c|#% increased Chaos Damage}}) have no effect on the Retch's damage output.
}}</ref> Therefore, in order to scale the Retch's damage, the player can increase the maximum duration of leech through {{c|mod|% increased Maximum recovery per Life Leech}}, increase their maximum life, increase their hit rate, slow debuff expiration by cursing the enemy with Temporal Chains, or cause the enemy to take more chaos damage.
===Example damage calculation===
A character has 8000 maximum life and {{c|mod|100% increased Maximum Recovery per Life Leech}}, setting the cap for its leech instances at 1600 total life. With 2% damage leeched as life, it caps a leech instance with 80,000 damage per hit, leeching 160 per second for 10 seconds. A 20% quality Retch will cause this hit to also inflict a DoT instance with a base DPS of 160x2.4=384 and the same 10 second duration.
Against an enemy debuffed to -30% chaos resistance and 120% increased damage taken, this DoT deals 384x1.3x2.2=1098.24 DPS for 10 seconds. If the enemy is also debuffed by Temporal Chains, the same DPS will be dealt for 12.5 seconds instead.
In this scenario, each 80,000 damage or higher hit will cause the Retch to deal an additional 13,728 damage (over 12.5 seconds).

#% of Life Leech applies to enemies as Chaos Damage: this modifier causes hits to apply chaos DoT with a DPS and duration based on the recovery and duration of that hit's life leech.
The Retch's DoT is independent of player recovery: hits will inflict it even if the player is on full life and loses their leech immediately, or when the player is unable to recover life due to Strength of Blood. Increases to player recovery, such as % increased Recovery Rate of Life or the more specific % increased total Recovery per second from Life Leech do not affect the Retch’s damage.
Because the DoT is considered reflected damage[1], it is not modified by the attacker’s offensive stats, only by stats on the enemy. Its duration can be extended by Temporal ChainsTemporal ChainsSpell, AoE, Duration, Curse, Hex Level: (1-20) Cost: (16-33) Mana Cast Time: 0.50 secRequires Level 24Curses all enemies in an area, lowering their action speed and making other effects on them expire more slowly.Base duration is (5.00-8.80) seconds +(0-1) metre to radius 50% less Effect of Curse against Players Cursed Normal and Magic Enemies have (15-29)% less Action Speed Other effects on Cursed enemies expire 25% slower Cursed Rare and Unique Enemies have (9-18)% less Action Speed

Ghost Reaver disables this mod completely. The Retch cannot deal damage in areas with Cannot Leech from Monsters, or against monsters with Life Cannot Be Leeched. It has no interaction with Damage Taken from Hits is Leeched as Life.
This modifier can be increased by Noxious and Fertile catalysts, up to 240%.

In flagellation, there lies freedom from temptation.. Instant leech does not result in more total damage, as the Retch’s DoT can stack indefinitely.
Interaction with proxies
Skills used by totems, traps, mines, mirages, and other proxies can inflict Retch DoT in the same way as the player. This uses the player’s stats for all calculations, including maximum life.[3] Because dead objects cannot leech, traps and mines can only leech before finishing their trigger/detonation animation.
Kills by Retch DoT from non-player objects are not attributed to the player, unlike most other forms of damage over time. When Retch DoT from no longer existing objects causes monsters to die, those monsters do not grant experience or flask charges, and their loot is unaffected by player item quantity and rarity[4].
Scaling
The Retch's base damage is bottlenecked by Maximum recovery per Life Leech, normally 10% of the player’s maximum life, whether it’s instant or not.[5] Therefore, in order to scale the Retch's damage, the player can increase the maximum duration of leech through % increased Maximum recovery per Life Leech, increase their maximum life, increase their hit rate, slow debuff expiration by cursing the enemy with Temporal Chains, or cause the enemy to take more chaos damage.
Example damage calculation
A character has 8000 maximum life and 100% increased Maximum Recovery per Life Leech, setting the cap for its leech instances at 1600 total life. With 2% damage leeched as life, it caps a leech instance with 80,000 damage per hit, leeching 160 per second for 10 seconds. A 20% quality Retch will cause this hit to also inflict a DoT instance with a base DPS of 160x2.4=384 and the same 10 second duration.
Against an enemy debuffed to -30% chaos resistance and 120% increased damage taken, this DoT deals 384x1.3x2.2=1098.24 DPS for 10 seconds. If the enemy is also debuffed by Temporal Chains, the same DPS will be dealt for 12.5 seconds instead.
In this scenario, each 80,000 damage or higher hit will cause the Retch to deal an additional 13,728 damage (over 12.5 seconds).

The Retch itself is not a league-specific item. However, the ingredients of the vendor recipe were tied to Talisman league. There are additional ways to acquire league-restricted items, see the article for the League-specific items for more details. Since version 3.14.0 the ingredients are also included in the core drop table.
