This page uses a pinned Data Dragon snapshot. It is not a verification of every in-game interaction or hotfix.
Stats and stacks calculate the state you enter. Nine outputs that cannot be derived from the source require in-game values. Special copied or possessed recasts and transfer restrictions are outside full simulation coverage.
This catalog covers normal Summoner’s Rift. Excluded does not mean removed from the game. The classification and its source are listed below.

Variable valuesScaling & formulas
Attacks deal (Lv1–11: 5–55 / Lv12–20: 60 + 4% Bonus health + ((1.25% Bonus health × 0.01) × 100% Ability power)) bonus magic damage. Against champions, they add a stack of An Acquired Taste for 5 seconds, up to 3 times.
At 3 stacks, Tongue Lash and Devour become empowered against that champion.
Ratio is equal to 1.25% per 100 bonus
Deals (75 + 100% Ability power) magic damage to the first enemy hit and Slows them by 50% for 2 seconds.
On champion hit, heals Tahm for 10 +5% of his missing Health and applies a stack of An Acquired Taste dealing (Lv1–11: 5–55 / Lv12–20: 60 + 4% Bonus health + ((1.25% Bonus health × 0.01) × 100% Ability power)) extra magic damage. If that champion already had 3 stacks of An Acquired Taste, they will also be Stunned for 1.5 seconds, consuming the stacks.
Activate Devour while your tongue is in midair to devour enemy champions who already have 3 stacks of An Acquired Taste from a distance when you hit them.
Dive down and then re-appear at target location, dealing (100 + 150% Ability power) magic damage and Knock Up all enemies in an area for 1 second. Hitting at least one enemy champion refunds 40% of the Cooldown and Mana cost.
Devoured allies can be taken along for the ride (but can always hop out early).
Passive: 15% of damage Tahm Kench takes is stored by his Thick Skin, increased to 42% if there are at least 2 nearby enemy champions. If Kench has not taken damage within 4 seconds, Thick Skin will rapidly be consumed to heal Tahm for 60%（(60–100 (Lv1–18))%） of its value.
Active: Convert all your stored Thick Skin into a Shield, lasting 2.5 seconds.
Tahm Kench devours a champion for a few seconds. He can Recast to spit them out.
Enemy Champions: Require 3 stacks of An Acquired Taste. Are devoured for up to 3 seconds and take 100 (+(15 + 0.07 × Ability power)% of their Max Health) magic damage. Tahm Kench is Slowed by 40% and Grounded during this effect.
Ally Champions: Are devoured for up to 3 seconds and are granted (650 + 100% Ability power) Shield which decays gradually after being spit out. Allies can also choose to exit early. Tahm Kench is Grounded during this effect, but can cast Abyssal Dive and gains 60% Move Speed for 3 seconds.
