Edgar Complete Build Guide: The Only Pure-Healer A-Rank, Lamplight Academy Bookbag Bash, Call of the Twisted City

Key Answer: Edgar is a 1.0 standard A-rank, with the Cosmos element, a Liquid Arc, JP CV Yuko Sanpei, a Lamplight Academy student + Eibon Antique Shop Esper, and the only pure-healing A-rank healer in the whole game. Core: E “Wild Current” hold-to-channel healing + Q “Finnegan’s Wake” 10-second healing field. The A-rank signature Arc “Call of the Twisted City” gives Healing Bonus +12-20% + Thea’s Night Tavern 4-piece (Healing Bonus +20%). A2 + A6 are the game-changing Eidolons; he’s playable at E0 and is a must-build stopgap godsend for new players.

A blue short-haired youth, a Lamplight Academy student, who whacks people with a big bookbag — Edgar is the only pure-healing A-rank healer in NTE 1.0, dubbed across the community as the “lazy healer,” “the Eibon Antique Shop family,” and “Lamplight Academy bookbag bash.” This article lays out his mechanics, build, Eidolons, recommended teams, and progression path all in one place.

Character Profile

A blue short-haired youth whose looks carry a maturity beyond his years, dressed in a white jacket + blue neckerchief + a golden key at his waist; his character design draws on traditional Nordic (especially Finnish) clothing. Though young, his demeanor is calm and old-souled — an Esper companion who often accompanies the protagonist (the Appraiser) at the Eibon Antique Shop.

His design concept is dead simple — he is the one in charge of “keeping your allies alive.”

2. Skill Set

Basic Attack [Combat Practice]

• A 5-hit Cosmos-element Esper-power combo, drawn from the close-quarters martial arts learned in Lamplight Academy PE class
• In the air he can dive-slam the ground for Cosmos-element AOE damage, scaling with fall height, up to +200%
• After a Perfect Dodge, the basic attack triggers a Bookbag Impact, dealing damage and reducing Stagger resistance

Shift (E) [Wild Current] ⭐ Core Healing

• Tap: deals Cosmos-element damage and restores the HP of the lowest-HP ally
• ⭐ Hold to charge into a sustained channeling state: continuously fires current at the target, dealing Cosmos damage and continuously healing the lowest-HP ally
• The longer you channel, the stronger the healing, but the cooldown extends with the channel duration (up to +9 seconds; the A2 awakening lowers the cap to 3 seconds)
• ⚠️ During channeling Edgar cannot dodge — he needs a shield or tank to cover him

Ultimate (Q) [Finnegan’s Wake]

• Deploys the “Vigil Domain” healing field, lasting 10 seconds
• Continuously deals Cosmos-element AOE damage to on-field characters and restores their HP
• ⭐ The domain stays on the field even after you swap characters — the core play is to deploy it and immediately swap back to your Main DPS
• Extend its duration via the “Key of True Knowledge”

Support [Weight of Knowledge]

• On swap-in entry, swings the bag for a smash, dealing Cosmos-element AOE damage
• On cast, gains 1 Key of True Knowledge (the cap depends on awakening)
• Each key extends the Ultimate’s duration by 3 seconds

Passive [Gentle Edge]

• When a Charge triggers, gains 120 Ultimate energy (30-second CD)
• Effectively lets you instantly fill the Ultimate

3. Eidolons / Resonance Chain (Awakening)

Eidolon	Name	Effect	Priority
A1	Observer Fond of Anomalies	When any ally uses a support skill, Edgar gains 1 Key of True Knowledge	⭐⭐⭐⭐⭐
A2	Anomaly Hunter Intern	Wild Current’s max cooldown-extension cap drops to 3 seconds (from 9)	⭐⭐⭐⭐
A3	One of the Eibon Detectives	Against allies below 30% HP, Wild Current healing +15%	⭐⭐⭐⭐⭐
A4	Skilled Tactician	Wild Current damage +50%	⭐⭐
A5	Guardian of the Antique Shop’s Light	Edgar max HP +20%	⭐⭐⭐
A6	Visitor from the Star of Curiosity	All allies within the Vigil Domain get +15% DEF	⭐⭐⭐⭐⭐

The Most Critical Eidolons

• ⭐ A6 (Prydwen’s top pick) — upgrades Edgar from a pure-healer into a “healer + damage-reduction support,” with strong synergy for characters whose damage scales off DEF (like Adler)
• A2 — solves the biggest pain point of Wild Current’s overlong cooldown

How Playable Is He at E0?

Playable, but the experience is incomplete — E0 Edgar is plenty for the healing duties of normal content, but the 9-second cooldown after a long channel will break your rhythm. For a standard A-rank, pulling at least A2 is recommended, and the practical experience improves dramatically.

4. Best Build

⭐ Top Arc: Call of the Twisted City

Stat	Value
Rarity	A-rank (4★ signature Arc)
Base ATK	395
Sub-stat	HP% +37.5%
Core passive “Cardboard Castle”	For 10 seconds after casting a Shift skill, Healing Bonus +12% (does not stack)
Refinement (M5)	Healing Bonus scales 12% → 14% → 16% → 18% → 20%

⭐ Strength note: because Wild Current is a long channeling skill, the healing-bonus buff is active almost the entire time.

Alternative 1: Mind Royale

• A-rank Liquid Arc
• Passive “Inspiration Terminator”: casting a Shift skill grants 10 Ultimate energy (20-second CD)
• Suits an Ultimate-rotation-focused build — the runner-up when the Ultimate is your main healing tool

Alternative 2 (stopgap)

Any A-rank Liquid Arc + an HP% sub-stat — good enough for the transition period

Gear: Thea’s Night Tavern 4-piece

Pieces	Effect
2-piece	HP +10%
4-piece	Healing Bonus +20%

The standard kit for a healer, bar none.

Transition set: Thea’s 2-piece + any HP set 2-piece — early on, before you’ve assembled the full 4-piece, prioritize getting the HP +10% 2-piece

Stat Priority

Slot	Priority
Main stat	Healing Bonus / HP% > DEF%
Sub-stat	HP% > DEF% > flat HP > flat DEF

5. Recommended Teams

1. Mainstream Stable Team (F2P top pick) ⭐

Main DPS + Sub-DPS + Edgar + any Buffer / tank

e.g.: Baicang (Main DPS) + Sakiri (Sub-DPS) + Edgar (healer) + Fadia (shield)

Good for general stage progression and clearing content as a new player

2. Cosmos-Element Core Team

Esper Zero + Hathor + Nanally + Edgar

Cosmos-element resonance provides a damage buff, with Edgar keeping everyone alive

3. Ultimate-Energy Rotation Team

Edgar + Hathor + Nanally / Mint + Jiuyuan

The core of a Charge-reaction team, with Edgar handling passive charging

4. High-Difficulty Boss Dual-Healer Team

Main DPS + Fadia (shield) + Edgar (healer) + Sub-DPS

A dual-survival setup, good for long fights and high-damage Bosses

⚠ Note: Edgar has a potential conflict with “Esper Cycle / Charge-reaction” teams — he doesn’t participate in elemental reactions, so he may crowd out a damage slot. But for any team with no healer slot at all, he is still the most easily obtained answer.

6. Build Priority Order

1. Level: just rush to Lv 60 (a support doesn’t need to push to 80). With spare resources you can take him to 70
2. Skill upgrades:
   • Wild Current ⭐⭐⭐⭐⭐ → Finnegan’s Wake ⭐⭐⭐⭐ → Weight of Knowledge ⭐⭐⭐ → Basic Attack Combat Practice ⭐⭐
3. Arc: max out Call of the Twisted City
4. Gear: Thea’s Night Tavern 4-piece, main stat Healing Bonus / HP%
5. Resonance chain: A1 → A2 → A3 → A6 (take A5 and A4 too if resources allow)

Upgrade Materials

• Lv 60→70: 125,000 Beetle Coins + 6 Whispers of Contradiction + 24 Colorful Stubs
• Lv 70→80: 150,000 Beetle Coins + 9 Whispers of Contradiction + 36 Colorful Stubs

7. Pull or Skip?

Verdict: No need to pull at all ✅

Edgar is a standard A-rank character, obtainable from new-player guarantees, event giveaways, and standard-banner accumulation — no pulls required.

Build Recommendation

Player Type	Recommendation
New open-beta player	✅ Recommended to build — a member of the Eibon family, obtained automatically as you progress the main story; a universal fill-in choice
F2P player	⭐ Stopgap godsend — solves your healing needs at E0, field-ready at level 60
Paying player	Skip or invest lightly — S-ranks like Fadia and Adler offer stronger survival solutions
True fans	A6 is the strongest upgrade, but it’s costly — assess your resources

Compared with Other Healers

Character	Mechanic	vs Edgar
Fadia (S, Psyche)	Damage-transfer shield (not pure healing)	Functions don’t overlap, can share a team
Adler (A)	Shield + offensive buff	High all-around strength
Edgar (A)	The only pure-healer	Single-purpose but irreplaceable

8. Community Memes / Reception

• “The only pure-healing A-rank in the game” — this is Edgar’s most important tag
• “Lazy healer” — just hold E or drop the Ultimate to keep the whole team alive; the skill floor is extremely low
• “Lamplight Academy bookbag bash” — the contrast meme of an A-rank healer who uses a bookbag as a weapon
• “The Eibon Antique Shop family” — the family bonds with the protagonist (the Appraiser), Tajido, and others
• “Why is there a pure-healing A-rank?” — early game versions had no stronger healer, so Edgar took on the “guaranteed healer” role
• “For true fans, or is Fadia the main healer?” — a false comparison; Fadia is an S-rank survival shielder with a different function; the real “main healer” is still represented by Edgar for now
• Tier list reception: Prydwen T3, Game8 C, nteguide B — “functionally complete but lacking damage buffs and elemental reactions” is the main reason he can’t reach T1
