| Gear priority 1 | Elemental DMG bonus |
| Gear priority 2 | Energy Regen (to rotation cap) |
| Substats | CRIT > ATK% > flat ATK |
Weapon: the signature rate-up weapon is the ceiling, but any high-rarity Caster weapon with an ATK% or energy main stat performs within ~10% — don't chase the weapon banner unless Yvonne is your long-term main.
