Edgar Overview

Rarity: A-Rank | Element: Cosmos | Role: survival | Arc: Liquid
Edgar is a Cosmos-element healer support whose core mechanic is using his skills and ultimate domain to heal teammates. As far as healers go, Edgar's skills mainly just heal—no extra buffs or utility. That makes him a pretty solid all-purpose, "jack-of-all-trades" kind of unit.
However, that also means Edgar isn't a must-pick for any specific team. Once a dedicated support for a particular team archetype drops, he's likely to get replaced.
But let's be real—versatile characters like Edgar are often the key for new players in the early game. So, let's take a closer look at his skills~
Edgar Skills
Skill Upgrade Priority:
Wild Current (Skill) > Finnegan's Wake (Ultimate) > Weight of Knowledge (Support) > Basic Attack
Prioritize upgrading his skill first, as it's his core means of continuously healing teammates. Upgrade his ultimate second, as it provides team-wide sustain within its domain. The support skill's main function is to stack his passive and extend the ultimate duration—upgrade it when you have spare resources. His basic attack has no supportive value at all, so leave it for last.
Basic Attack - Combat Practice

|
Combat Practice |
Applies what he learned in Lamplight Academy's physical education class to perform up to 5 consecutive attacks that deal Cosmos DMG. |
|
Calculated Landing |
Press Basic Attack while airborne to plunge, dealing 1 instance of Cosmos DMG to an area upon impact. Increases DMG based on fall height, up to 200%. |
|
Critical Riposte: Crisis is Opportunity |
Triggers when using Combat Practice after a Critical Dodge. Charges toward the target and uses his backpack to unleash a Flow attack, dealing 1 instance of Cosmos DMG to an area and reducing Break. |
Skill - Wild Current

Hold to enter a channeling state, continuously casting Current at the target, dealing Cosmos DMG and continuously healing the teammate with the lowest HP.
The CD of Redirect Skill: Wild Current increases based on the duration of use.
Ultimate - Finnegan's Wake

Immerses in his own thoughts, unleashing a labyrinthine domain for 10s. Deals 1 instance of AoE Cosmos DMG. Heals the current character over the domain's duration.
Support Skill - Weight of Knowledge

This bag is really heavy. Edgar charges toward the target and swings his bag with all his might, dealing 1 instance of Cosmos DMG to an area.
Passive
|
Gentle Edge |
Charge Enhancement: Grants 120 Ultimate Energy instantly when a character triggers Charge using a Support Skill. Disables Ultimate Energy gain from Lebenblumes when hitting Slowed targets afterward. Cooldown: 30s |
|
Unchanging Warmth |
Cast Redirect Skill Wild Current or Support Skill Weight of Knowledge to gain a Key of Truth, up to 3 keys. Each Key of Truth extends the duration of Ultimate: Finnegan's Vigil by 1s. |
LIFE SKILL - KNOWLEDGE IN ACTION
|
Lvl. 1 - Edgar increases traffic by 18. Lvl. 2 - Edgar reduces ingredient consumption rate by 1%. Lvl. 3 - In Owner's Selection, customers are more likely to choose the highest-priced dishes. Lvl. 4 - Edgar reduces ingredient consumption rate by 1%. Lvl. 5 - Edgar increases traffic by 27. |
Edgar Awakening
|
Anomaly-Loving Observer Awakening 1 |
Grants Edgar 1 Key of Truth whenever any teammate casts a Support Skill. |
|
Intern Anomaly Hunter Awakening 2 |
Caps the max cooldown extension from Wild Current at 9s. |
|
One of the Eibon Detectives Awakening 3 |
Increases Wild Current's healing effectiveness for allies with current HP below 80% by 15%. |
|
Skilled Strategist Awakening 4 |

|
Guardian of the Antique Shop's Light Awakening 5 |

|

A3 ≥ A1 > A6 > A5 >> A2 > A4
- A3 / A1 – Highest Priority
A3 increases healing effectiveness by 15% for allies below 80% HP — a direct boost to his core role. A1 grants a Key of Truth whenever any teammate uses a Support Skill, greatly improving his ultimate uptime and team survivability.
- A5 – Second Priority
+20% Max HP — improves Edgar's own survivability so he can stay on the field and keep healing.
- A6 – Third Priority
Grants 15% DEF to all allies inside Finnegan's Wake — a nice team-wide defensive bonus, but not game-changing.
- A2 – Fourth Priority
Caps the cooldown extension from Wild Current at 9s — very little practical benefit for healing or support.
- A4 – Lowest Priority
Wild Current DMG +50% — Edgar is a healer, not a damage dealer. Leave this for last.
Resonance Effects
|
R1 Pursuit of Knowledge 3-Awakening Bonus |
Increases the skill level of Wild Current, Finnegan's Wake, and Weight of Knowledge by 1. |
|
R2 Keen Insight 6-Awakening Bonus |
