Adler Complete Build Guide: A-Rank Yipuen Butler, Free S-Rank Umbrella Signature Arc, Karma + Five Aggregates Team Shield

Key answer: Adler is a 1.0 A-rank standard character — element Incantation, Arc type Synthesis, JP CV Toshiyuki Morikawa (Kaito Kid / Sephiroth), the acting manager and butler of the Yipuen Antique Shop. Core mechanic: Karma stacking (20 stacks) → cast E “Evil’s Bane” to consume Karma + apply a team-wide Blessing shield + boosted Incantation-damage DoT. The “Umbrella” signature Arc is completely free (from the Prepare for Rain Anomaly commission). E6 “All Forms Are Void” is the power spike (shield 8→12 sec). He is the best healer / shield substitute for players who do not have Fadia.

ℹ Naming note: This site uses “Adler” (阿德勒). All Traditional-Chinese official sources use this name consistently. “Kuili” (魁立) is not a name for Adler, and is likely an early unofficial mistranslation.

A British-gentleman look, narrow smiling eyes, an exquisite cane, calm and seasoned — Adler is the acting manager and butler of the Yipuen Antique Shop, dubbed by the community “unexpectedly likeable”, “the face of the shield archetype”, “Hotori’s best partner”, and “an A-rank price tag with an SS-rank voice actor” (voiced by Toshiyuki Morikawa). This guide covers his mechanics, gear, Eidolons, recommended teams, and build path all in one place.

2. Skill Kit

⭐ Core Mechanic: the Karma Stacking System

Item	Rule
Trigger source	Normal Attack hits, Gear-skill hits
Stacking rules	Deliverance (Normal Attack combo) grants +1 Karma per hit Ignorance (plunge attack) grants +1 Karma Liberation (aimed shot) grants +2 Karma (reliably)
Cap	20 stacks
Consumption	All Karma is consumed when the E skill is cast

Normal Attack

Skill	Description
Deliverance	Up to 5 cane strikes dealing Incantation damage, +1 Karma per hit
Liberation	Aim mode, precise single-target shots, +2 Karma per shot
Ignorance	Plunge attack, AoE Incantation damage on landing, +1 Karma

E (Gear) — Evil’s Bane ⭐⭐⭐⭐⭐ Top upgrade priority

Summons “Sunya” onto the enemy’s position, dealing AoE Incantation damage + a DoT, and applies a “Blessing” shield to the whole team.

• Consumes all Karma stacks on cast; each stack of Karma gives Adler +2% skill damage (+40% skill damage at max stacks)
• Base shield duration: 8 seconds (extended to 12 seconds at E6)
• ⭐ It is best to stack at least 15 Karma before casting to maximize the shield and damage

Q (Ultimate) — Tranquility

Summons the five aggregates — Form, Sensation, Perception, Formation, Discernment (Rupa, Vedana, Sanna, Sankhara, Vinnana), each dealing 5 hits of Incantation damage to enemies in the area.

• ⭐ Smart targeting: with 2 or more enemies it hits multiple targets; against a single enemy it hits twice for double total damage (great for boss fights)

Passive / Support — Clear Insight

Boosts Incantation damage and can apply a random debuff (exact values per the in-game text).

Core Rotation

1. Open with Normal Attacks / aimed shots to build 15-20 Karma
2. Cast E (Evil's Bane) → consume Karma, apply team shield, burst DoT
3. Swap to your Main DPS for damage (the shield persists after swapping)
4. Save the Ultimate (Tranquility) for boss fights or AoE clearing

3. Eidolons / Awakening (A1–A6, Buddhist Five-Aggregates theme)

Eidolon	Name	Effect	Priority
A1	Form	Instantly gain 20 Karma when casting the Ultimate	⭐⭐⭐
A2	Sensation	Each stack of Karma grants Adler +3% damage bonus	⭐⭐⭐
A3	Perception	Blessing shield strength +20%	⭐⭐⭐⭐
A4	Formation	When the shield breaks, absorbs overflow damage equal to 50% of Adler’s DEF	⭐⭐⭐⭐
A5	Discernment	When casting the Ultimate, recover 20 points of Ultimate energy	⭐⭐⭐
A6	All Forms Are Void	Blessing shield duration extended to 12 seconds (from 8)	⭐⭐⭐⭐⭐

Key Eidolons

• ⭐ A6 is the biggest power spike —— the shield is extended from 8 to 12 seconds, perfectly covering a full E-skill rotation, upgrading Adler from a “point-and-trigger shielder” into a “permanent shield support”
• A3 + A4 —— a large shield-value boost that makes Adler far more durable in high-difficulty content
• An A-rank standard character, easy to max out —— long-term play makes E6 easy to reach naturally

How Playable Is He at E0?

Playable at E0, comfortable at E1–E2, transformed at E6. At E0 he already handles all content from beginner to mid-game as an emergency shield and source of light AoE damage; if you don’t have Fadia, E0 Adler is the best healer / shield substitute.

4. Best Gear

⭐ Arc: Umbrella (the free S-rank signature!)

Stat	Value
Base ATK	25 (395 at max level 80)
Sub-stat	DEF% —— 21% at Lv1 / 52.5% at max

Stat Priority

Slot	Priority
Main stat	DEF% —— scales both shields and damage
Secondary	Energy Recharge / Rotation Strength
Last	CRIT Rate, CRIT DMG

⭐ Both Adler’s shield value and skill damage scale with DEF, so stacking DEF is not a purely defensive choice — it simultaneously raises the team’s shields and his own Incantation-damage DoT.

5. Recommended Teams

1. Scorch Team (the mainstream comp) ⭐

Baicang (Main DPS, Incantation) + Mint / Daffodill (Sub-DPS) + Sakiri (Buffer) + Adler (shield)

Adler provides Incantation DoT and shields, a perfect fit for the Scorch rotation

2. Hexed Team

Nanally (Main DPS) + Jiuyuan (Sub-DPS) + Sakiri + Adler

Adler’s shield protects Nanally during her long startup animations

3. Discord Team

Baicang / Sakiri + Daffodill + Haniel (Healer) + Adler

Covers the Incantation, Chaos, and Psyche elements to trigger Discord reactions

4. Budget / F2P Lineup

Any Main DPS + Adler + Haniel + Protagonist (Esper Zero)

⭐ Adler is the “A-rank standard substitute for Fadia (the S-rank healer / shield)“

6. Build Priority

1. Ascend the level to 60 (a support doesn’t need to rush 80 — poor value)
2. Skill upgrades: E (Evil’s Bane) ⭐⭐⭐⭐⭐ → Q (Tranquility) ⭐⭐⭐⭐ → Normal Attack ⭐⭐⭐ → support skill ⭐⭐
3. Umbrella Arc: refine it first once you get it free
4. Kingdom’s Guard 4-piece: defensive stats, all DEF% main stats
5. Talent upgrade materials: Beetle Coins, Blurred Numbers, Moon-in-Water Tokens, Unsolved Numbers, Distorted Numbers (about 25,000–150,000 Beetle Coins total for ascension)

7. Should You Pull?

Player type	Verdict
Do you need to pull actively?	❌ Not at all —— A-rank standard, given free in the main story
A must-build for F2P?	✅ Strongly recommended —— free S-rank Arc + a 4-star A-rank shield slot = close to an S-rank experience
Players without Fadia	⭐ Adler is the best healer / shield substitute
Players with Fadia	Adler works as a backup, a build for true fans

8. Community Memes / Reception

• “The Yipuen Antique Shop butler” —— his profile wins fans over, with players calling him “unexpectedly likeable” (Bahamut)
• “The face of the shield archetype” —— usable at E0, transformed at E6, high long-term value
• “Hotori’s best partner” —— a fellow shop member with lots of story interaction, giving off CP energy in the lore
• “A savior for budget players” —— the free S-rank Umbrella + the 4-star Adler = close to an S-rank experience
• “Toshiyuki Morikawa endorsing a luxury experience” —— his JP voice actor is a legend in the industry (Kaito Kid from Detective Conan, Sephiroth from Final Fantasy VII, Griffith from Berserk); an A-rank character with a top-tier voice actor leads players to say “an A-rank price tag with an SS-rank voice actor”
• Tier-list placement: T1 (LDPlayer TW site), “highly functional, great as an early-to-mid game bridge”
