Rengar + Circle of Death
A Tier Combo
Abuses Circle of Death's 5x damage bug on specific champions — Rengar's normal and empowered W both trigger it for instant burst far above tooltip. Lean into trading HP since heal-on-hit ramps with damage taken; empowered W's CC immunity means short of one-shots, you'll heal up and execute full-HP squishies in moments.

Maokai S Maokai's best augment. One auto = full health. 
Zac S Zac heals so frequently that Circle of Death procs constantly. 
Nunu & Willump S Q deals massive damage, but don't build Rod of Ages. Maokai S Protein Shake gives huge sustain — combined with Maokai's % HP regen passive, you never die. 
Vladimir S Vlad's Q and R heals each proc 5x Circle of Death damage — late-game team-wipe nukes. Do NOT build Rift Maker — its omnivamp interaction overrides Q's heal, killing the trigger. Zac S Use Circle of Death to convert massive heals into magic damage — pair with Zac's huge HP and % HP regen to play laser tower. Higher HP = bigger heal = bigger CoD damage; build HP and healing-boost hexes. 
Warwick S Warwick's auto and Q heals both proc 5x Circle of Death; Q has 100% AP scaling + % damage. Cast Q at half HP for max heal = max CoD damage. Nunu & Willump S CoD Nunu can deal massive damage to enemies via huge minion-Q heals. Avoid Rylai's — once you build it, Q on enemies stops dealing damage. Keep exploring
