Fiora

Vitals from Duelist's Dance (P) deal 3% (+4% per 100 bonus AD) of max health as true damage, armour or not. Riposte (W) parries Infected Bonesaw (Q) cast and stuns him mid-trade, and Grand Challenge (R) heal recovers faster than Maximum Dosage (R) regen during long duels.

Vitals from Duelist's Dance (P) deal true damage that ignores stacked HP. Riposte (W) parries Infected Bonesaw (Q) cast and stuns Mundo mid-trade, and Grand Challenge (R) heal recovers faster than Maximum Dosage (R) regen during long duels.

Riposte (W) parries the Q3 edge knock-up and stuns Aatrox out of the combo; Duelist's Dance (P) Vital procs deal true damage that ignores his drain-tank build, beating extended trades.

Riposte (W) parries the Bandage Toss (Q) stun and stuns Amumu back. Duelist's Dance vital procs ignore his stacked armor, and the four Vitals from Grand Challenge (R) carry the damage, 3% (+4% per 100 bonus AD) of max health as true damage, then heal her in any 1v1.

Riposte (W) parries Feral Scream (W) silence and stuns Cho mid-trade, Lunge (Q) dodges Rupture (Q) knockup, and Grand Challenge (R) vital popping shreds his HP pool. Continuous Duelist's Dance (P) damage out-trades the slow Q windup.

Riposte (W) parries the Apprehend (E) knock-up and stuns Darius mid-trade, while Vitals from Duelist's Dance (P) bypass his HP build with true damage. Grand Challenge (R) heal outscales the Hemorrhage (P) 5-stack window during long duels.

Riposte (W) parries Parrrley (Q), stunning Gangplank if it blocked an immobilise, denying barrel-Q crit windows; Lunge (Q) dashes through Powder Keg (E) placements without taking the slow. Grand Challenge (R) hits four vitals before Gangplank can stack chained barrels safely.

Riposte (W) parries Decisive Strike (Q) but only slows, since silence is not Immobilizing, opening a free Bladework (E) trade. Lunge (Q) dashes through Judgment (E) spin radius and Grand Challenge (R) hits four vitals before Garen can stack Perseverance (P) regen between trades.

Duelist's Dance (P) vital procs deal true damage that ignores Gragas resistances; Riposte (W) parries Body Slam (E) stun and reflects the CC during W. Grand Challenge (R) hits four vitals before Drunken Rage (W) damage reduction can rotate twice.

Duelist's Dance (P) vitals also deal true damage and Lunge (Q) dashes ignore Hallowed Mist (W) range. Riposte (W) parries Skip 'n Slash (E) dash empowered auto and reflects CC, and Grand Challenge (R) hits four vitals before Gwen can re-mist.

Riposte (W) parries Counter Strike's AOE stun on recast and reflects its CC back onto Jax, gutting his only kill window. Duelist's Dance (P) Vital procs deal true damage, so armour does nothing. Sterak's Gage absorbs it, but two Vitals burn through the shield.

Riposte (W) parries the Bear Trap on a Rope (Q) yank or the Jousting (E) recast knockback and reflects the stun back onto Kled. Duelist's Dance (P) Vitals deal true damage that ignores resistances, so Skaarl drains and Kled dismounts before Fiora is ever low.

Riposte (W) parries the Realm of Death (R) activation — the ultimate is spent, Mordekaiser gets nothing back and waits 140 / 120 / 100 seconds. Lunge (Q) repositions onto vitals and Grand Challenge (R) true damage out-trades the Indestructible (W) shield economy.

Riposte (W) parries the point-and-click Wither (W) — the slow never lands and Nasus waits out the full cooldown with no peel. Duelist's Dance (P) vitals deal max-health true damage, so stacked armor does nothing.

Fiora's Riposte parries the next incoming ability and stuns the caster — Unspeakable Horror's fear gets reflected as a stun on Nocturne, cancelling his own all-in. Duelist's Dance vital procs punish the predictable leap landing position.

Fiora's Riposte parries Reckless Swing and turns Olaf's own commit into a stun on himself, cancelling the all-in. Her Duelist's Dance vitals then chip him with true damage every few seconds, and stacking HP does nothing against it.

Fiora's Riposte parries Searing Charge and stuns Ornn instead, cancelling the whole Brittle combo before it starts. Her Duelist's Dance vitals then deal true damage every few seconds, and Ornn's stacked armor does nothing against it.

Fiora's Riposte parries Heroic Charge and reflects the stun back onto Poppy, cancelling her single committed engage. Duelist's Dance vital procs deal true damage that ignores Poppy's Armor stacks every few seconds.

Fiora's Riposte parries Blinding Assault and stuns Quinn mid-cast, cancelling her only anti-melee tool. Duelist's Dance Vitals refresh every few seconds and deal true damage her thin HP pool cannot absorb, so every second near Fiora costs more than the trade is worth.

Fiora's Riposte parries the empowered Ruthless Predator stun outright, reflecting it back onto Renekton and killing his all-in before it starts. Duelist's Dance Vitals refresh every few seconds and deal true damage, so his armor and health do nothing to slow her down.

Riposte (W) parries the next spell or auto and stuns the caster back — the perfect counter to Ki Burst (W), Riven's only lockdown in lane. Bladework (E) plus Lunge (Q) keep her sticking, and Grand Challenge (R) Vital procs deal percent-HP true damage that ignores armor.

Riposte (W) parries Permafrost (E) and reflects the stun back onto Sejuani, and Lunge (Q) plus Bladework (E) keep Fiora sticking outside the 650 Arctic Assault (Q) range. Grand Challenge (R) Vital procs deal percent-HP true damage that shreds Sejuani's stacked armor.

Grand Challenge (R) Vital procs deal percent-HP true damage that bypasses Sett's tank stats and Grit shield. Riposte (W) parries Facebreaker (E) and reflects the stun back, killing the lockdown chain before Grit can fill the Haymaker (W) bar.

Riposte (W) parries Shadow Dash (E) and stuns Shen mid-cast, wasting his engage on an 18s cooldown at rank 1. Lunge (Q) at 400 units plus Bladework (E) keep her glued in melee, and Grand Challenge (R) Vitals deal true damage that ignores the HP Shen stacked.

Grand Challenge (R) Vital procs deal percent-HP true damage that ignores armor and magic resist — the entire Rod of Ages plus Warmog's stack is wasted. Riposte (W) parries the Fling (E) root, removing Singed's only hard CC tool against her.

Riposte (W) parries Decimating Smash (Q) on the charge windup and stuns Sion back. Grand Challenge (R) Vital procs deal percent-HP true damage that scales on max HP — exactly what Sion stacks — and Lunge (Q) plus Bladework (E) keep her sticking outside Q range.

Fiora's Riposte (W) parries Chomp (Q) and answers with a 25% slow, not a stun — it only stuns on an immobilizing effect, which he lacks. Opening with Subjugate (R) still gets parried. Without Chomp there is no AD steal, and Duelist's Dance true damage outpaces King's Tribute.

Riposte (W) absorbs the Spinning Slash (E) hit and answers with a slow; she only stuns if she parries crowd control, which Tryndamere lacks. Lunge (Q) then walks her around him faster than he repositions, and Bladework (E)'s slow keeps his approach short of attack range.

Fiora's Riposte (W) parries Thundering Smash's stunning auto and stuns Volibear back instead. Her Duelist's Dance Vitals deal true damage (damage that ignores Armor and Magic Resist — no defensive stat reduces it), so Volibear's tank stack does nothing in the 1v1.

Riposte (W) parries Steel Tempest (Q) third-stack knockup, removing his all-in CC. His Way of the Wanderer (P) shield absorbs Vital true damage like any other damage; break it with an auto, then rotate for the Vital. Riposte also cancels Last Breath (R) when Fiora has Vitals up.

Riposte W parries Mortal Steel Q tornado knock-up and stuns Yone back, since the tornado is an immobilising effect, killing his only CC tool in the 1v1. Duelist's Dance vital procs heal Fiora through Spirit Cleave shield damage, and Grand Challenge R sustains the all-in.

Lunge Q is a short-cooldown dash that resets on vital procs, chaining out of Dark Procession W cage repeatedly. Riposte W eats the empowered Last Rites Q auto for a 25% slow and cripple, only a stun on an immobilising effect. Grand Challenge R sustains her through the swarm.

Riposte W parries the Q2 knock-up recast and stuns Zaahen for 2s during the all-in window; parried on Q1 alone it is a 25% slow instead. Duelist's Dance vital procs shred his drain build with true damage, and Grand Challenge R sustains Fiora through Grim Deliverance heal.

Riposte W parries Elastic Slingshot E landing knockup and stuns Zac on the way back, neutralising his only engage. Duelist's Dance passive vital procs shred his tank HP pool with true damage, and Grand Challenge R sustains Fiora through Unstable Matter W ticks.
