Tahm Kench + Fan The Hammer

Tahm's autos and Q proc bonus damage based on max HP — with hexes you reach absurd resists and HP. He doesn't lack damage; just build 6 tank items.

Use Mayhem's infinite HP stacking with Rift Maker to convert HP into AP; with Adapt enabled, Overlord's Bloodmail works too.

For Mejai's stack lineups — Heartsteel + Goliath/Tank Engine makes tongue reach across the screen, Q chunks stack-snipers half HP. Since stacks are plentiful, don't aggressively stack HP — Heartsteel is just for size.

With Duskblade, a single Q stacks 3 passive layers.
