Edgar Guide
A 4★ Cosmos sustainer who heals on the move with a channelled Wild Current, opens a survival domain, and doubles as a Charge-reaction energy battery. Judge him purely as sustain: bottom-tier as a damage pick (community DPS C), but a serviceable budget healer (Support A).

Ratings
Contextual: a serviceable budget healer with a useful Charge battery in the right core — never a damage slot, and the community rates him bottom-tier as a damage pick.
Community read — ZeroLuck tier-vote, Patch 1.0 (live, n=21 votes across roles): DPS C 0.69/5 (13) · Hybrid C 0.67/5 (3) · Support A 3.0/5 (5). The community votes him bottom-tier as damage (C, n=13) but a viable budget healer / support (A) — judge him purely as sustain, not as a damage slot.
Trend: recently shifted D → C in the hybrid role on the rolling tier movement — his support placement is stable. Watch the live tier list for the current standing.
Strengths
- Mobile, target-following channel heal — sustains without standing still
- Finnegan's Wake heals and (A6) hands the team +15% DEF
- Charge-reaction energy battery for Cosmos / Charge cores
- Fully usable at A0 on a 4★ arc — extremely budget-friendly
- Game-recommended arc + clear stat path straight from the data
Weaknesses
- No buff output — pure heal + energy, not a damage support
- Wild Current cooldown scales with channel length
- Battery value only exists in Charge-reaction teams
- Low personal damage unless you invest A4 into Wild Current
Gameplay — Keys of Truth & the Sustain Domain
Edgar runs a small support economy. Casting Wild Current or Weight of Knowledge banks Keys of Truth (max 3). Each Key extends his domain ultimate by 1s, so the loop is always bank Keys → channel heal → open a longer Wake.
Why he is also a battery
- Gentle Edge — refunds 120 Ultimate Energy when a Support Skill triggers Charge (shared Esper reaction, 30s CD)
- Unchanging Warmth — his support casts bank Keys, so support uptime is also domain uptime
- Anomaly-Loving Observer (A1) — any teammate Support cast banks a Key, decoupling his Wake from his own field time
The decision with Edgar is the team, not the build: in a generic line he is a solid mobile healer; in a Cosmos / Charge core next to Chiz his Gentle Edge battery is worth a full extra ultimate cycle — meet that condition and a 4★ punches well above its rarity.

Skill
Wild Current
Hold to channel Current at the target — it deals Cosmos DMG and continuously heals the lowest-HP teammate. The cooldown of the Redirect version scales with how long you channel, so you trade healing throughput against uptime. This is Edgar's actual job: a held, target-following team heal that also does damage. It is also the cast that builds Keys of Truth.
Ultimate
Finnegan's Wake
Opens a labyrinthine domain for 10s, deals one instance of AoE Cosmos DMG and heals the active character over the whole duration. Each Key of Truth (from Wild Current / Weight of Knowledge) extends the domain by 1s, up to 3 extra seconds. With A6 it also grants every ally inside +15% DEF — turning his ultimate into a survival window, not just a heal.
Normal Attack
Combat Practice
Up to a 5-hit Cosmos combo, with an airborne plunge (Calculated Landing, up to +100% from fall height) and a Critical Riposte (Crisis is Opportunity) after a Critical Dodge that charges in and reduces Break. Edgar is not a DPS, so this is filler and Break utility — keep it low priority.
Chain Skill
Weight of Knowledge
A swap-in charge that swings his bag for one instance of AoE Cosmos DMG. Cheap, and like Wild Current it grants a Key of Truth — a clean way to bank a domain-extension Key when you rotate Edgar in. Lowest upgrade priority.
Passive
Gentle Edge
Charge Enhancement: instantly grants 120 Ultimate Energy when a character triggers Charge with a Support Skill (30s CD). Charge is one of NTE's shared Esper Cycle reactions, not a personal mechanic — Edgar plugs into it the same way Chiz does, which is why he is a strong energy battery for Charge-reaction teams, not only a healer.
Passive
Unchanging Warmth
Casting Redirect Wild Current or Support Weight of Knowledge grants a Key of Truth, up to 3. Each Key extends Finnegan's Wake by 1s. This is the loop that ties his kit together: use his support tools off-field, bank Keys, then open a longer sustain domain.
Skill scaling — Lv 1 → Lv 11
Real ratios (% of ATK) from the in-game codex. Ultimate Finnegan's Wake more than doubles between Lv 1 and Lv 11 — and it is also the heal source, so it is the single most valuable book investment for Edgar.
| Source | Lv 1 | Lv 11 |
|---|---|---|
| Normal Attack — Combat Practice | 30.9% | 66.7% |
| Skill — Wild Current (7-hit) | 80% ×7 | 172.7% ×7 |
| Ultimate — Finnegan's Wake (heal) | 400% | 863.6% |
| Chain Skill — Weight of Knowledge | 200% | 431.8% |
Both passives — Gentle Edge and Unchanging Warmth — are flat utility (Charge battery, healing scaling) with no per-level damage row, so they are not surfaced in this table.
Awakenings
Priority: A4 → A1 → A3 → A6 → A5 → A2, then A8 / A7. He is fully functional at A0 — awakenings raise his ceiling, they do not gate his job. A4 is the biggest jump if you want Wild Current to deal real damage; A1 is the biggest sustain-uptime jump.
A4
Skilled Strategist
Wild Current DMG +50%. His only real damage line is the channel — this is the single biggest power jump if you ever want him to contribute damage while he sustains.
A1
Anomaly-Loving Observer
Grants 1 Key of Truth whenever any teammate casts a Support Skill. Decouples his domain-extension from his own casts — in a team that swaps and supports often, his Wake is permanently extended.
A3
One of the Eibon Detectives
+15% Wild Current healing effectiveness on allies below 30% HP. A targeted clutch-heal boost — exactly when the heal matters most. High value in hard content.
A6
Visitor from Planet Curiosity
Grants +15% DEF to all allies inside Finnegan's Wake. Converts his ultimate into a team mitigation window on top of the heal — a real survivability swing in endgame.
A5
Guardian of the Antique Shop's Light
Edgar's Max HP +20%. More personal bulk so he survives to keep channelling — solid quality of life, not a throughput gain.
A2
Intern Anomaly Hunter
Caps Wild Current's cooldown extension at 3s. Lets you channel longer without punishing the cooldown as hard — smooths his uptime once you actually use long channels.
A8
Keen Insight
Converts 3% of any teammate's lost Max HP into 1 Charge for his Vigil (up to 20, resets on cast). Niche scaling that only pays off in damage-heavy fights.
A7
Pursuit of Knowledge
+1 skill level to Wild Current, Finnegan's Wake and Weight of Knowledge. A flat stat-stick — unlock last.
Best Arc
These picks are grounded in his in-game cultivation data and arc-type compatibility (Edgar equips Liquid arcs) — not invented tier claims.
Cassette Set & Stats
- 2-piece: HP +10%
- 4-piece: Healing Bonus +20%
Tailor-made for a healer: both bonuses map straight onto his game-recommended Healing Bonus / HP stats, directly raising the throughput of Wild Current and Finnegan's Wake.
- 2-piece: ATK +10%
- 4-piece: +25% ATK for 20s after casting a Skill
Only for a Wild Current damage build with A4 — Edgar casts Skill often so uptime is reliable, but for a pure sustainer Thea's Night Tavern is strictly better.
Stat Priority
Best Team
Cosmos · Liquid. Channels Wild Current to heal the lowest-HP ally on the move, banks Keys of Truth, then opens Finnegan's Wake for a sustained heal (and team DEF with A6). Off-field support that keeps a fragile carry alive.
Cosmos Main DPS. Edgar's Gentle Edge feeds the shared Charge Esper reaction with an instant 120 Ultimate Energy. Chiz's A6 Thirty-Three Days adds +15% Bonus Cosmos DMG on his Grain — every Ultimate Edgar batteries up now hits 15% harder, on top of A2 Fireworks in Silence (10% of current Grain as per-second interest in Surplus). Battery + healer in one back-row slot for a Cosmos / Charge core.
Anima burst carry. Squishy and aggressive — her A1 To Know, To Balance grants +5% ATK per Lethal Rose Pact target on the field (up to +15%), which only pays off if she stays on the field long enough to gather, bind and detonate. Edgar's mobile Wild Current channel keeps her topped through the entire setup, so she banks the full A1 stack instead of swapping out to survive.
Psyche team buffer. Her A4 Seaside! Beach episode! makes the next attack after an Ensemble trigger deal +100% additional DMG while in Paranormal Ace — a burst window that requires the on-field carry to keep attacking, not topping themselves off. Edgar carries the sustain load so Haniel can focus on the buff cycle. See the Chiz Team guide where this Cosmos / support core is laid out in full.

Optimal Rotation
Bank Keys off-field
Before you need the heal, cast Weight of Knowledge on the swap-in (and Wild Current taps) to bank up to 3 Keys of Truth. With A1, every teammate Support cast also banks a Key for free.
Channel Wild Current
Hold Wild Current on the target. It heals the lowest-HP ally continuously and chips Cosmos damage. Watch the channel length — the Redirect cooldown scales with it (capped at 3s with A2).
Open Finnegan's Wake
With Keys banked, open the domain. Base 10s, +1s per Key (up to 13s). It heals the active character for the full duration and, with A6, grants every ally inside +15% DEF — your big survival window.
Hold and re-key
Keep the active carry inside the domain. Re-tap Wild Current / Weight of Knowledge during the window to start rebuilding Keys for the next Wake.
Swap out, stay useful
Edgar's heal and Charge battery (Gentle Edge) work from the back row. Rotate to your carry once the team is topped and the domain is up — he does not need field time to keep contributing.
Golden rule: bank Keys before you need the domain — never open Wake on 0 Keys.

Should You Pull?
Pull if…
- You want a flexible 4★ sustainer that heals on the move instead of standing still
- You run a Cosmos / Charge team — Gentle Edge is a free 120 Ultimate Energy battery
- You have a fragile carry (Jiuyuan, Chiz) and no dedicated shielder
- You want a forgiving back-row healer with a team-DEF window at A6
- You like budget-friendly investment — he is fully usable at A0 and on a 4★ arc
Skip if…
- You want a damage support — Edgar's contribution is healing and energy, not buffs
- You already run a stronger 5★ sustain unit and have no Charge synergy to exploit
- You dislike channelled skills — Wild Current rewards holding, not tapping
- You expect a self-sufficient carry — he is a pure support, never a solo clear
New / casual players: a mobile heal plus a survival domain makes Edgar one of the most forgiving early picks. As a 4★ he is easy to obtain and needs zero investment to do his job — a safe pick that smooths story and mid difficulty.
F2P / low-spend: a solid free sustain option because his value does not gate behind dupes. A0 on his game-recommended 4★ arc keeps the full sustain kit and the Charge battery — there is no paywall. Good while you lack a 5★ healer, not an end-state.
Invested / endgame:his ceiling is limited. A6 turns Finnegan's Wake into a +15% team-DEF window and A1 keeps it permanently extended; slotted into a Cosmos / Charge core next to Chiz his Gentle Edge battery is worth a full extra ultimate cycle. Outside a Charge team he stays a plain budget healer — serviceable, and a built 5★ sustainer replaces him outright.
Bottom line: judge him purely as sustain. The community rates him bottom-tier as a damage pick (DPS C) but a serviceable budget healer (Support A) — a fine cheap sustain option if you lack a 5★ healer, with a useful Charge battery for the right core. Pick him to keep a team alive, never to push numbers.
FAQ
Is Edgar a healer or a DPS?
A healer first, with a small damage and utility kicker. His Wild Current channel heals the lowest-HP teammate while he is on the field, and Finnegan's Wake sustains the active character. He does Cosmos damage on those casts, but his damage is incidental — you build him for sustain and energy, not for a damage slot.
Is Edgar good for a 4★?
Yes. He is one of the more useful free / 4★ supports because his value does not gate behind dupes: a mobile target-following heal, a domain that heals and (with A6) hands the team +15% DEF, and a Charge-reaction energy battery. F2P players get the bulk of his kit at A0 on a 4★ arc.
What is the best Arc for Edgar?
Call of the Twisted City — and that is the game's own recommendation in his cultivation data, a 4★ Liquid arc with an HP% sub-stat that matches his recommended attributes (Healing Bonus and HP). Mind Royale is the game's listed alternate; Youthful Fantasy is the higher-rarity 5★ Liquid option only if you also invest in his Wild Current damage.
What is the best Cassette Set?
Thea's Night Tavern 4-piece: the 2-piece is HP +10% and the 4-piece is Healing Bonus +20% — both line up directly with his game-recommended Healing Bonus / HP stats, so it is the cleanest sustain set for him. Shadow Creed (ATK +10% / +25% ATK after Skill) is the generic alternative if you are leaning into a Wild Current damage build.
What stats should I prioritise?
Straight from his in-game recommended attributes: Healing Bonus > HP% > HP. He scales his job off healing output and bulk, not ATK or crit — do not build him like a DPS. Universal survival sub-stats (HP%, DEF%) round him out.
Which Awakening matters most?
A4 (Wild Current DMG +50%) is the biggest single jump if you want him to contribute damage while he sustains; A1 (free Key of Truth on any teammate Support cast) is the biggest quality-of-life jump for his domain uptime. Priority: A4 → A1 → A3 → A6 → A5 → A2, then A8 / A7. He is fully functional at A0.
What is Charge Enhancement on Gentle Edge?
Charge is one of NTE's shared Esper Cycle reactions — not an Edgar-specific mechanic. Several units interact with it (Chiz also has a Charge Enhancement passive). Gentle Edge simply hooks Edgar into that shared system: when a Support Skill triggers Charge, he instantly refunds 120 Ultimate Energy on a 30s cooldown. That makes him a strong battery specifically for Charge-reaction teams.
Is he worth it for casual / story play?
Very much. A mobile heal plus a survival domain makes story and mid-difficulty content far more forgiving, and he asks for no investment to do that job. The Charge battery and A6 team-DEF only start to matter when you push the hardest endgame fights.
