Conqueror
ConquerorGain stacks of adaptive force when attacking enemy champions. After reaching 12 stacks, heal for a portion of damage you deal to champions.: The guide reserves this keystone swap for matchups needing attack speed specifically because spells cannot reliably land against a dash kit - Irelia is the named example.
Nashor's Tooth
Nashor's ToothIncreases Attack Speed, Ability Power, and Cooldown Reduction trades health for the payoff: The guide's listed downside is no health, but against a spell-dodger the attack-speed return is worth it: enough autos to stop needing Q at all.
Defiant Dance
W – Defiant DanceIrelia charges a strike that deals more damage as she charges. She takes reduced physical damage during the charge. can still punish the walk-up: Her parry blunts a real chunk of the auto damage the whole plan leans on if she times it against the engage, so the tech reduces her counterplay rather than deleting it.

Level by Level Game Plan
| Level | Primary Goal | Lane Position | Trading Opportunities | Kill Windows | Setup Opportunities |
|---|---|---|---|---|---|
| 1 | Read her dash commitment before doing anything | Hold the wave edge, out of easy poke | None yet; bait first | Low | Watch whether she commits |
| 2 | Bank a level lead without fishing spells | Push only on a clean read | Autos only unless she is clearly stuck | Low | Track her second point for |

| 4-5 | Build toward the attack-speed spike | Hold the wave, avoid extended trades | Short and controlled, nothing fished | Low | Watch for a jungler assist on either side |

| Mid Game (11-16) | Play the side-lane threat | Split if the side lane is open, otherwise stay with the wave | The ultimate whenever she is stranded without a dash to answer it | High off a clean R | Track her ultimate cooldown before committing |
| Late Game (16+) | Stay inside the guide's late-game window | Frontline, banked |
No group commitment without the ultimate ready; that rule does not bend here either | Whenever no shield break has touched him | Her true damage on-hit ignores whatever he has built by now |

Teamfight Tips
| Aspect | Mordekaiser | Irelia |
|---|---|---|
| Primary Role | Frontline duelist who isolates whichever dash-reliant carry |
Diving skirmisher who resets |
| Target Priority | Irelia herself once she has spent a dash engaging Whichever priority target the ultimate can pull out of the fight entirely Whoever already committed to the frontline, once the ultimate is down |
The lowest-health target Backline carries once a reset opens the path Turns onto Mordekaiser himself only after his ultimate is already used |
| Objective Control | Pulls whoever is contesting the pit into Hold Indestructible's shield for the moment a dive starts |
Waits for a Uses |
| Positioning | Waits for a target to be stranded without a dash to answer with before committing the ultimate Hold the frontline with the shield banked before engaging |
Stays just outside the frontline for a reset Saves |
| Other Tips | The auto-focus plan from lane carries into teamfights too - autos do not miss the way a fished Q or E does |
Bladesurge's reset makes chaining a kill safer than opening one; look for the low-health target first |
