費德提克+靈活轉換S+[Hard to scale] Fiddle's Q deals % max-HP magic damage, doubled on feared targets. At 1467 AP, one fear+Q = 100% max HP. Forge: AD (with Adapt) > AP > magic pen. Hide in bush, one Q scares them dead.
菲歐拉+任務:鋼鐵雄心S+[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.
古拉格斯+靈活轉換S+Gragas W gives AP-scaling % damage reduction with a 2.5s invuln after channel. At 2050 AP, 100% reduction. But you have to spend the empowered auto before recasting W, so there's a downtime gap — not perma. Forge: AD (with Adapt) > AP > HP > resists.
派克+巨人SPyke passive converts 14 HP into 1 AD; Goliath gives 35% HP and 15% AD, so 8 HP = 1 AD — late, 1000+ AD easy. R scales with both AD and lethality — full-HP squishies are in execute range.
睿娜妲‧格萊斯克+任務:烏莉特的法帽SRenata's passive marks enemies; ally damage consumes the mark for % max-HP magic damage. At 600 AP, hits 14% max HP. Stack AP for damage and AS for marking frequency. Damage is attributed to Renata, so magic-pen forge works.
賽特+巨人SIn Mayhem, Sett's W stores up to 35% max HP in grit. W damage scales with grit cap and AD, so stack HP and AD — late, you one-shot. Forge: AD > HP > MS. E pulls both sides together; if both sides have at least one unit (minions count), it stuns — wait for full grit, EW guaranteed.
慎+基本功夫SShen's Q empowers his next 3 autos with % max-HP magic damage that scales with AP. Lvl 18 base is 4%; with Q's spirit blade hitting an enemy, it goes to 7% — three autos = 21% max HP. At 400 AP, three autos hit 45% max HP. Spirit-blade pull positioning is huge — hit-vs-miss roughly doubles damage.
