"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."
― Tahm Kench

You are a jungler, duhh.

good for gap makers and closes.

Optional good if you will be farming jungle more or counter jungling.

'The whole world's a river, and I'm its king.'
Tahm Kench travels Runeterra's waterways, feeding his insatiable appetite with the misery of the unsuspecting. The singularly charming gourmand savors every moment of his victims' suffering. A deal with Two-Coats may carry you to wherever you wish, but your journey will most assuredly end in the depths of despair.
