Artifacts

Yelan’s artifacts are simple, since she doesn’t benefit from ATK bonuses. Anything that gives HP%, Burst Damage, or Energy Recharge works for her.

1. 4pc Emblem of Severed Fate (By far her best set if her energy requirements are above 130%)

2. Some combination of 2pc sets: Noblesse Oblige, Tenacity of the Millelith, Heart of Depths, and/or (if you need the energy) Emblem of Severed Fate.

All of the 2pc combinations are close enough to basically be the same damage, which changes primarily depending on buffs active in your team composition.

Sands - When using an ER% weapon like Favonius Warbow, an HP% Sands is advised.

When using her signature weapon and other non-ER weapons, she’ll need an ER% Sands.

Goblet - Hydro% beats HP% by about 7% damage, though depending on your team’s buffs on Yelan, there are niche cases where an HP% Goblet is competitive or better.

Circlet - Crit Rate% or Crit Damage%, as usual. Alternatively, HP% is typically within 1-2% of a Crit circlet, unless you are running a double Hydro team with Yelan’s signature weapon; then Crit circlet wins by about 9%

For substats, prioritize meeting your ER% requirements first, then Crit%/HP%. Unlike typical characters, the gap between Crit stats and HP% for Yelan is quite small so prioritize substat quantity over the type of substats (Crit vs HP%). When in doubt, use the calculator in the master sheet.
