Skarner should leverage his terrain control and tankiness to dominate river and objective zones, limiting Ekko's mobility and pick potential.
Prioritize controlling walls and chokepoints to maximize (E) stun reliability and suppress Ekko's escape options.
This matchup is a control vs scaling fight where Skarner must deny Ekko's safe farming and scaling windows through objective pressure and ganks.
Jungle Plan
Path camps to approach gank lanes where walls enable reliable (E) pins and (R) suppression picks.
Fight for river and objective terrain control before dragon or Rift Herald to deny Ekko's access and set up picks.
Use vision and lane priority to counter-jungle safely after Ekko commits to farming or ganking, especially before his level 6 power spike.
Danger windows
Avoid isolated river fights before level 6 where Ekko's mobility and (W) stun can punish overextensions.
Be cautious contesting dragon or Rift Herald if Ekko's lanes have priority or his (R) is available for defensive resets.
Low-health clears or forced smite fights without lane priority create high risk of losing tempo to Ekko's burst and mobility.
Early game
Start with a standard clear that leads toward lanes with wall-heavy terrain to maximize gank threat with (E).
Contest first Scuttle only if nearby lanes have priority to avoid risky isolated fights against Ekko's mobility.
Avoid early river skirmishes without vision control, as Ekko's mobility and (R) make counter-invades dangerous before level 6.
Power spikes
Level 3 unlocks Skarner's full (Q)-(W)-(E) combo for reliable CC; use this to pressure Ekko before his level 6.
Skarner's ultimate (R) provides strong suppression for picks and objective control; leverage it to isolate Ekko or priority targets.
Ekko's level 6 (R) and first AP item spike increase his threat; respect these windows by avoiding forced fights and focusing on vision and objective setup.
Win conditions
Convert terrain control and reliable (E) stuns into objective setups around dragon and Rift Herald to deny Ekko scaling.
Use suppression (R) to pick off isolated targets or force Ekko into unfavorable teamfights where Skarner excels.
Maintain river vision and track Ekko's pathing to counter-gank and punish his early farming patterns, denying him safe scaling.
