Whether you’re chasing the explosive Flame Alchemist or strategizing fusion combinations with the Elric brothers, this guide covers everything from basic acquisition to advanced team compositions.

Quick Overview: All FMAB Units in Update 66

Flame Alchemist (Roy Mustang) – The Meta-Defining Burn Specialist

How to Get Flame Alchemist

The Flame Alchemist is a Celestial Unit based on Roy Mustang from Fullmetal Alchemist and represents the crown jewel of Update 66. Currently available exclusively through Banner 2 with a 0.5% chance drop rate, this unit has instantly become essential for any competitive roster.

Acquisition Methods:

• Primary: Banner 2 summons (0.5% base rate, 1% during rate-up events)
• Pity System: Guaranteed after 200 pulls on featured banner
• Event Currency: 5,000 Alchemy Tokens during FMAB event (limited time)
• Trading: Available through player marketplace (expect 50,000+ gems value)

Stats & Abilities Breakdown

Placement AOE with big burn focus. Placement hits a hill area and applies multiple DOTs (burn, blaze, black flame variants). The unit’s true power comes from its unique stacking mechanics:

Base Stats (Level 1):

• Damage: 618 (plus 741.6 flame damage)
• Range: 18 (Circle AoE)
• SPA: 4.5
• Placement Cost: 450

Max Stats (Level 100 + Overlord+):

• Damage: 7,622 (plus 9,146.4 flame damage)
• Range: 35
• SPA: 1.8
• Total DPS: 15,000+ with full burn stacks

Unique Mechanics

Passive – “Burning Hatred”: reduces target SPA on repeated hits (stacks up to -50% SPA for 10s)

Active Ability – “Broken Man’s Echo”: 5 rapid attacks each applying a different burn DOT at ~200% effectiveness; short cooldown (~12s)

Best Usage Tips

Based on extensive testing, Flame Alchemist excels in these scenarios:

• Boss Killing: Great on bosses or waves where single-target DOT stacking shines
• Synergy Teams: Pair with units that amplify DOT or apply additional crowd-wide burn/bleed to trigger passive faster
• Placement Strategy: Position on high ground for maximum coverage
• Evolution Priority: Focus on burn damage multipliers over raw attack

Armored Alchemist (Alphonse Elric) – The Ultimate Tank Support

Acquisition & Evolution Path

The Armored Alchemist — “Alons” (Support/Tank with Time Stop) brings unprecedented defensive capabilities to any team composition. Unlike his brother, Alphonse requires a more complex acquisition process:

How to Obtain:

• Primary Drop: Drops from legend stage (Act 3) with 2% drop rate
• Transmutation Crafting: also appears in transmutation/legend crafting in some builds
• Event Shop: 3,500 Alchemy Tokens (while event active)
• Evolution Materials: Requires 50 Steel Fragments + 1 Philosopher’s Stone Shard

Abilities & Role Analysis

Ground placement, line/circle AOE; applies weaken to enemies in range and gets a regenerative armor counter when stunned (cleans stun and counterattacks)

Core Mechanics:

• Soul Armor Passive: Redirects 40% of team damage to himself while regenerating
• Anti-Stun Counter: Passive grants bonus damage to nearby enemies and an anti-stun mechanic
• Time Stop Ultimate: At higher upgrades gains encasement/time-stop effect (map or local time stop)
• Stone Serpent Summons: summons stone-serpent-like attacks

Strategic Implementation

Use as a buffer/tank for comps that need stun immunity or timed pauses. Time-stop can swing clutch moments — pair with heavy-damage burst units to maximize the freeze window

Optimal Team Positions:

1. Front line tank position for maximum damage absorption
2. Mid-field support for time stop coverage
3. Choke point defender with area denial

Cost Efficiency: Placement around 800k; strong utility rather than raw DPS

Short Alchemist (Edward Elric) – The Versatile Buffer

Getting Edward Elric

The Short Alchemist — Edward Elric (Buffer / Versatile) serves as the linchpin for Alchemy-based team compositions:

Acquisition Routes:

• Banner Summons: Appears on banner and via some transmutation routes
• Guaranteed Method: Complete “State Alchemist Exam” questline (15 stages)
• Trading Value: Approximately 30,000-40,000 gems on player market

Unique Buffer Mechanics

Circle AOE buffer with tags that buff allied units. Has “Master Alchemist” passive that every minute tags a random friendly unit and grants either accelerate (if friendly has damaging status) or pressure (if not)

Ability Breakdown:

• “Blood Packed” Ability: transfers part of Edward’s damage into a random nearby ally for duration
• Sanguin Stars System: Gains “Sanguin Stars” from takedowns (each +2.5% range up to ~25%)
• Transmutation Unlock: Unlocks offensive/defensive transmutation when paired with the armored unit

Optimization Strategies

Make Edward your support pillar — keeps carries doing more damage and extends their reach. He pairs especially well with DOT or bleed comps to exploit the accelerate effect

Fusion Mechanics: Offensive & Defensive Brothers

Understanding the Fusion System

The most innovative mechanic in Update 66 is the Fusion Transmutations — Offensive Brothers & Defensive Brothers system:

Activation Requirements:

• Transmutation ability when you have both Short Alchemist (Edward) and Armored Alchemist on the field and both are maxed to the required upgrade
• Both units must be Level 80+
• Requires 1 Transmutation Circle item (rare drop from Alchemy Trials)
• 10-second channel time (interruptible)

Offensive Brothers Build

Effect: Merge into a single unit with burst nuke on transform (+50% attack for next waves, map HP reduction effect on enemies, and stacking bonuses if multiple DOT units present)

When to Use:

• Best use: Aggro burst comps that want to shorten boss fights or clear a heavy wave quickly
• Tournament finals for clutch damage
• Infinite Castle waves 150+
• Speed running story mode

Defensive Brothers Build

Effect: Merge into a defensive powerhouse that applies massive weaken AOE, grants base stocks, and has a map-wide time stop when reaching low stock once (deals damage scaled by enemies alive)

Strategic Applications:

• Best use: Defensive lanes, clutch stalling, or to buy time for rebuild/upgrade during tough waves
• Survival mode endurance runs
• Protecting vulnerable DPS units
• Emergency recovery situations

Fusion Planning Tips

If you plan to use fusion, prepare both units and plan where you want them to spawn — offensive for nuke windows, defensive for stall mechanics. Fusion depends on both units’ traits; invest accordingly

Additional FMAB Units Guide

Tattooed Alchemist – The Element Cycler

The Tattooed Alchemist / Glitched Mystical (Element Cycle Dot-Spinner) offers unique versatility:

Core Mechanics:

• Hybrid placement that cycles elemental DOT effects each wave (air/terra/aqua/ignis)
• each form applies different status combos (e.g., wind shear, poison, black flame)
• Passive “Explosive Finish” detonates on enemies below 50% HP for extra damage

Optimization: Works best where you can force the element you want (or against enemies that let you exploit the detonation)

Cost Analysis: Cheap placement (~950), hybrid scaling. Good midline dot spread and conditional burst

Kind King – The Infinite Range Striker

Kind King / Infinite Range Striker revolutionizes positioning strategies:

Unique Mechanics:

• Circle AOE with map-wide reach (infinite range)
• SPA scales with distance: closer = faster attacks
• Has passive “Ultimate Eye” that adjusts SPA based on target distance

Placement Strategy: Place him where he can hit close targets to maximize attack speed. Great for single-target carry roles on boss waves or clustered enemies

Investment Required: Extremely high DPS potential when attacking nearby threats; placement cost higher (1–2k)

Frequently Asked Questions

Which FMAB unit should I prioritize first?

Flame Alchemist offers the best immediate impact for most players. His versatility and damage output make him valuable in every game mode. However, if you’re building for long-term success, securing both Elric brothers for fusion potential provides unmatched flexibility.

How long will the FMAB event last?

Based on previous collaboration patterns, expect 3-4 weeks of active event time. Banners typically remain for an additional week after event conclusion, but drop rates return to normal.

Can I get FMAB units after the event ends?

Yes, but availability becomes limited. Banner units remain in the general pool at reduced rates. Event-exclusive units like Truth Seeker may return during anniversary events or special reruns.

Are FMAB units worth it for F2P players?

Absolutely! The pity system ensures even F2P players can secure at least one premium unit. Focus on Flame Alchemist or the Elric brothers for maximum value. Use our code guides to maximize your free resources.

Rough estimates based on average luck:

• All banner units: 150,000-200,000 gems
• Evolution materials: 50+ hours of farming
• Fusion unlocks: 20,000 additional gems
• Total time investment: 100-150 hours over event duration

Troubleshooting Common Issues
