Aurelia vs Edgar

Aurelia vs Edgar — cross-Attribute Support matchup (Psyche vs Cosmos).

TL;DR — Quick Pick

Pick Aurelia if…

  • Your roster needs a Psyche Support more than another Cosmos Support.
  • You prefer Aurelia's Polyphonic Round + Darkstar identity over Edgar's Finnegan’s Wake + Field.
  • Low early priority — build later if you need Plasma-Arc Psyche utility.

Pick Edgar if…

  • Your roster needs a Cosmos Support more than another Psyche Support.
  • You prefer Edgar's Finnegan’s Wake + Field identity over Aurelia's Polyphonic Round + Darkstar.
  • Serviceable filler, but Cosmos S-Ranks (Zero, Chiz, Hotori, Shinku) usually take the slot.
Verdict

Aurelia (Psyche) and Edgar (Cosmos) are both Support picks, but they shore up different Attribute gaps. Prefer Aurelia when low early priority — build later if you need Plasma-Arc Psyche utility. Prefer Edgar when serviceable filler, but Cosmos S-Ranks (Zero, Chiz, Hotori, Shinku) usually take the slot. Check signature Arcs, team shells, and who you already own before committing pulls.
