Mercuria
Who is Mercuria?
Mercuria is a 6-star Spirit-afflatus, Mental-damage Support and flex Sub-DPS whose buffs are tied to allied incantation ranks (prydwen rating 9). Her Ultimate grants [Rank Up], raising incantation rank by 1 for rank calculations, and she builds [Cosmic Energy] (up to 25 stacks at P0) that grants the party an undispellable +2% damage per stack. She also heals via Self-Focusing. Source: prydwen.gg/re1999/characters/mercuria.

Build Guide
🔮 Best Relic / Echo Set
Resonance: Hyperphrenia pattern at R10 (survival with Crit stats); Elucidation as a damage-focused alternative. Portray: Portrait investment notably smooths her buff cycling. Source: prydwen.
⚔ Best Light Cone / Weapon
One with the Flow (best-in-slot — prydwen first). Alternatives in order (prydwen): Melodies Old and New; Balance, Please; Starlight Wellspring; Her Second Life.
📊 Substats Priority
👥 Best Teams
Universal buffer/healer — her undispellable damage buffs fit almost any team. She has strong synergy with characters like Lucy and Marcus (per prydwen). Run her with a main carry plus a second support, using her Self-Focusing healing to cover sustain.
F2P Verdict
Her best psychube is One with the Flow, with Melodies Old and New, Balance, Please, Starlight Wellspring and Her Second Life as alternatives. Note she is clunky at P0 and benefits meaningfully from Portrait (Portray) investment to cycle her buffs without self-sabotage — a real consideration for low-spend players. Source: prydwen.
Frequently Asked Questions
Is Mercuria good in Reverse: 1999?
Yes — prydwen rates her 9. She provides extremely high, undispellable team damage buffs through [Cosmic Energy] (up to 25 stacks at +2% damage each) and her [Rank Up] Ultimate, and she heals via Self-Focusing, making her useful in almost any team.
What is the best psychube for Mercuria?
One with the Flow is her best-in-slot on prydwen, followed by Melodies Old and New, Balance, Please, Starlight Wellspring, and Her Second Life.
Does Mercuria need Portrait (Portray) investment?
She benefits meaningfully from it. Prydwen notes she is clunky at P0 and needs Portrait investment to cycle her buffs without self-sabotaging, so low-spend players should expect a rougher rotation until invested.
Should I pull Mercuria?
Worth it if you want a near-universal buffer/healer with undispellable team damage buffs. The caveats are potential overlap with supports you may already own and her clunky P0 gameplay before Portrait investment.
