NTE Edgar build v1.2 — Arcs, modules, teams

Edgar in 30 seconds

A convenient A-rank Healer, worth building 1 copy as a swap-in sustain unit if you lack healing; not a priority if you already have a better healing support.

★★★ 3/5

Best Edgar build

Role

Support / Healer (Cosmos) — heals based on HP, restoring health steadily; used as a quick swap-in: jump in when an ally's HP drops then swap back out, not staying on field continuously.

Community lists place Edgar in the B group (some even lower): a healer who does one thing well — keeping the team alive — convenient but offering no damage buffs. Foundational value, not a carry.

Best Arcs (ranked)

1Call of the Twisted City BiS Best Arc: raises Healing Bonus every time Redirect Skill is used — since Edgar channels his Skill for a long time, he enjoys the buff for nearly its full duration.
2Mind Royale Support option: charges Ultimate energy faster when casting Skill plus adds Break Intensity.

Best module sets

4 Thea's Night Tavern BIS for a healer: [2] +10% HP raises healing amount, [4] +20% Healing Bonus — directly boosts healing output.

Stat priority

Main stats: Healing Bonus › HP%

Substats: HP% › Charge Efficiency › HP › DEF%

Verdict confidence: medium — his healer role, the Call of the Twisted City arc, and the Thea's Night Tavern set agree across many sources; the lower substat order is inferred from standard healer conventions.
