FioraS+ Tier Combo[Hard to assemble] Heartsteel + Tank Engine stack infinite HP, Overlord's Bloodmail converts HP into AD. With Fiora's passive, around 2500 AD a single vital procs 100% max-HP true damage.
GalioS+ Tier ComboGalio W reduces both physical and magic damage — stack AP, MR, and HP and your reduction can hit 100%. After taunt lands, the reduction extends 2s beyond channel; with 300+ haste you're effectively immune full time.
PantheonS+ Tier Combo[Hard to scale] Pantheon's W gets bonus health scaling — once you hit ~25,000 HP, W deals 100% max-HP physical damage. Forge: HP > AD. Weak early, scales into tank-heavy matchups; max-rank ult has innate 30% armor pen and his enhanced E grants armor/MR from health.
RellS+ Tier ComboCentered on Tank Engine + Cruelty. Rell's hex pool is extra clean, and combining them gives extreme CC + huge sustained damage for 1v5 plays. With both hexes, Rell becomes a different champion.
AlistarS Tier ComboAlistar's Q is group CC and procs Colossus multiple times for an instantly huge shield — high haste means frequent Q, basically unkillable. Build full tank; Colossus has 5s CD, so dump full combo each fight, then Q to proc Colossus — bigger shield per enemy hit.AlistarS Tier ComboTanky enough that no one dies. Operation + luck = win.
AmumuS Tier ComboStack Triple-Stack Dragon. Forge: take omnivamp.
Cho'GathS Tier ComboUse R-stack HP + Heartsteel + Tank Engine for instant 10k+ HP and absurd survival/damage. Pure tank doesn't lack damage; for more damage add a magic Sunfire (Radiant Echoes).
+Mundo's E converts HP into huge AD — with stacked Heartsteel, you're both tanky and can one-shot squishies. Mundo's hex pool is exceptionally clean — top-tier tank hexes spawn often.
