"Boy, the world's one river, and I'm its king. Ain't no place I ain't been; ain't no place I can't go again."
Passive:Tahm Kench stores a percentage of the post-mitigation damage he takes as grey health on his health bar, up to a maximum of 300% of his maximum health. While there are at least 2 nearby visible enemy champions, either dead or alive, the damage stored into grey health is increased.

45 / 50 / 55 / 60 / 65%
While Thick Skin is available, and after taking no damage for 4 seconds, Tahm Kench rapidly heals himself to restore 45% − 100% (based on level) of his grey health. Every 0.264 seconds he heals for 10% of his maximum health.
Active:Tahm Kench converts his current grey health into a shield that lasts for 2.5 seconds.
Thick Skin shield value and grey health percentage heal are both boosted by effects that increase heal and shield power. This means Tahm Kench can technically heal more than the normal amount of grey health and get a shield bigger than his maximum health.
At level 18 Tahm Kench would need 53.8% heal power to heal for 100% of the damage he takes, reduced to 34.9% with Revitalize, 23.1% with Spirit Visage, and 6.9% with both.
Grey health converts all post-mitigation damage, Thick Skin effectively grants Tahm Kench a form of true damage mitigation.

Allies can also input a movement command after the same delay to force Tahm Kench to use Regurgitate in the target direction, unless they are immobilized.
Known by many names throughout history, the demon Tahm Kench travels the waterways of Runeterra, feeding his insatiable appetite with the misery of others. Though he may appear singularly charming and proud, he swaggers through the physical realm like a vagabond in search of unsuspecting prey. His lashing tongue can stun even a heavily armored warrior from a dozen paces, and to fall into his rumbling belly is to tumble into an abyss from which there is little hope of return.
Craving the smell of coins over all other earthly delights, Tahm Kench rises from his river kingdom each Lunar Revel, seeking to barter with mortals. Though his targets are almost always left destitute, with the proper reverence and careful wording it is possible to escape his bargains unimaginably wealthy.

Tahm Kench's dance has him play the tune he hums in 'The River King' with his tongue (Rift Scuttler will join him if he dances near her).
Tahm Kench's design and playstyle may be loosely based on the Banderhobb, a toad-like creature from the Forgotten Realms universe which kidnaps unsuspecting victims by swallowing them alive and carrying them to its master's lair.
In VALORANT on the Ascent map (Mid Bottom), there is a park bench crafted with his likeness. This is most likely a reference to the "Unbench the Kench" meme.
