2025.S1.3 patch had noticeable buffs to Electrocute. It's generally better than Conqueror against squishy teams.

Electrocute is harder to run on assassins now due to the removal of Eyeball Collection in Season 15. First Strike is pretty much dead after repeated nerfs.

Conqueror is the primary rune alternative to Electrocute for Evelynn. For some background, I stalked a couple Masters-Challenger players who have been running this rune page in Season 14, but I have been testing this with moderate success all the way back to when Evelynn was first reworked. You should ideally pick Conqueror into tanky, brawler-heavy, melee, and low-range comps. You are mostly playing to farm for powerspikes, but you have increased skirmishing strength and higher Q damage when Conqueror is stacked. The playstyle is similar to Diana where you powerfarm and look for good fight angles, and it can help you get a tempo lead through the early/mid game objectives which becomes absolutely essential in Diamond+.

Pros of Conqueror Evelynn:
- Eve stacks Conqueror really fast
- Similar damage to Electrocute from full combo and more sustained dps
- Precision tree is decent: Triumph, Legend: Haste, Cut Down > Coup de Grace
- Can 1v1 more junglers early, slightly safer against invades
- Stronger 2v2 top or 3v3 contest scuttle and grubs (important for Feats of Strength)
- Most people don't expect the increased skirmishing power of Conqueror Eve

Cons:
- Less upfront burst to kill carries
- Doesn't help your ganks that much
- Hard to run Inspiration tree for free boots, extra punishing if you fall behind early
- Have to get used to different playstyle

If you get ahead with this build, Eve is harder to kill, still does a lot of dmg, and is extra annoying. With Conqueror stacked, her ult is also more likely to execute than if you were running Electrocute.
