This is a scaling splitpush duel where Fiora must manage vital procs and parry windows to avoid Darius's all-in threat.
Fiora should avoid giving Darius extended trades that let him stack passive and heal, instead focusing on short, vital-based trades and side-lane pressure.
Trading pattern
Take short trades by hitting accessible vitals with (Q), then back off before Darius stacks five passive bleeds.
Save (W) to parry (E) pull or (Q) outer edge, punishing predictable attempts to engage.
After using (W), avoid extended trades as you lose your key defensive tool and become vulnerable to his damage.
Danger windows
Be cautious when (E) pull is available as it can lock you in for his full combo.
Avoid extended trades once Darius stacks five passive bleeds, especially near his (Q) outer edge for healing.
After you use (W), you lose your parry and become vulnerable to his crowd control and damage bursts.
Early game
Use (Q) to safely proc vitals and avoid extended trades before your first item spike.
Hold (W) to parry (E) pull or (Q) outer edge to prevent being locked down or chunked.
Avoid fighting near Darius's minion wave early to reduce his passive stack buildup and healing.
Power spikes
At level 6, use (R) to force extended duels and chase Darius through multiple vitals for healing and damage.
After your first dueling item, pressure side lanes to force isolated fights where your mobility and vitals excel.
Respect Darius's level 6 (R) execute window and his first item spike that increases his durability and damage for extended trades.
Win conditions
Win by proccing vitals efficiently with (Q) and (R), forcing isolated side-lane duels where you can chase and heal.
Deny Darius extended trades that let him stack passive and heal by resetting trades early.
Scale into splitpush pressure after your first item spike and use (W) to negate his key crowd control for favorable all-ins.
