Ekko is a scaling AP assassin who wants to avoid prolonged melee trades and instead look for short burst trades using (Q) and (E).
Sett has high early lane pressure and wants close-range brawls, so Ekko must manage spacing to avoid giving Sett easy grit stacks or melee access.
Trading pattern
Use quick (Q) and (E) bursts to trade and immediately disengage before Sett can retaliate with grit-backed (W) or (E) stun.
Avoid engaging with (E) if you can't land (Q), as missing it often leads to losing trades against Sett's retaliation.
Punish Sett after he wastes (E) or misses his (W) center by stepping forward for short trades or wave pressure.
Danger windows
Respect (E) pull and stun threat, especially when you are near minions or the wave is clustered.
Be cautious when Sett has built grit and can use (W) shield and true damage; avoid prolonged trades during this window.
After (R) is available, avoid overextending as he can reposition you into his team or follow-up damage.
Early game
Avoid extended trades before level 3 when Ekko lacks the full (Q)-(W)-(E) combo to threaten Sett's engage.
Use early wave control to keep Sett at a distance and prevent him from easily landing (E) pulls or building grit for (W).
Prioritize hitting level 3 to unlock your full trade combo and increase threat in lane.
Power spikes
Level 3 unlocks your full (Q)-(W)-(E) trade combo; use this to force Sett to respect your burst and avoid melee trades.
Level 6 (R) gives you a strong all-in, defensive reset, and burst window; track (R) to choose safe engage moments.
Sett's level 6 (R) and first bruiser item increase his brawl threat; respect his displacement and shield timings to avoid getting caught in unfavorable fights.
Win conditions
Use your mobility and (W) stun setup to create short burst trades and disengage before Sett can retaliate.
Deny Sett melee access by maintaining spacing and punishing missed (E) or (W) cooldowns with poke and wave control.
Leverage your level 6 (R) for picks, defensive resets, and roams to snowball the game and avoid prolonged Sett brawls.
