To beat Amius the Lunar Architect in the Cursed City of Sintranos, you must counter his phase-specific mechanics using targeted debuffs rather than relying purely on top-tier Legendary champions. Landing consistent Block Buffs, Decrease Attack, Heal Reduction, and Leech shuts down the boss's wipe mechanics across both forms.
Amius Phase Mechanics and Wipe Conditions
Amius shifts between two forms throughout the fight, altering his threats and resetting your debuff setup:
- Form 1 (Primary Form): Amius casts a self-shield scaled to his maximum HP alongside a Counterattack buff. Attacking him while these buffs are active triggers heavy counter-hits against your squad. Amius is immune to Turn Meter reduction, and enemy MAX HP damage skills are capped against him.
- Form 2 (Alternate Form): Upon transforming, Amius cleanses all debuffs from himself. In this form, his offensive scaling increases, and his multi-hit attacks inflict Sleep, Stun, and Eclipse debuffs while he attempts to regenerate large amounts of health.
Essential Roles and High-Value Epics
Winning the fight requires timing specific debuffs to neutralize the active form's abilities.
| Debuff / Buff | Primary Function Against Amius | Capable Epic Champions |
|---|---|---|
| Block Buffs | Denies Form 1 Shield and Counterattack | Uugo, Fenax, Umbral Enchantress |
| Decrease ATK | Mitigates lethal Form 2 burst hits | Ghrush the Mangler, Peydma, Hotatsu |
| Heal Reduction | Stops Form 2 HP regeneration | Venomage, Bonekeeper, Morag Bronzelock |
| Leech | Sustains allies without relying on burst heals | Ghrush the Mangler, Deacon Armstrong |
| Ally Protection | Absorbs multi-hit AoE damage | White Dryad Nia, Trumbor, Toragi the Frog |
Notable Epic Champions
- Ghrush the Mangler: Covers multiple survival requirements by placing Decrease Attack on his A1, Continuous Heal on his A2, and Leech alongside Decrease Accuracy on his A3. His Defense scaling aids his baseline survivability.
- Uugo: Places a 60% Decrease Defense and Block Buffs on a 3-turn cooldown with her A2, stopping Form 1 shield generation when timed properly. She also provides healing and an emergency multi-ally revive.
- Venomage: Applies Heal Reduction, Decrease Attack, and Poisons via her A2. Her passive reduces incoming damage to all allies based on the number of debuffs on Amius.
- White Dryad Nia: Reduces ally skill cooldowns with her A3 and provides damage mitigation through Ally Protection and Continuous Heal on her A2.
Stat Benchmarks and Gear Requirements
Build your champions to meet these stat targets to ensure debuffs land and your team survives incoming hits:
- Accuracy: Aim for at least 250 Accuracy on Normal difficulty and 350+ Accuracy on Hard difficulty.
- Speed: Tune your team between 220 and 250 Speed to cycle cooldowns and react before Amius takes critical turns.
- Survivability: Target at least 55,000 HP and 3,500 Defense on both supports and damage dealers. Defense-scaling champions have an easier time meeting these thresholds.
- Artifact Sets: Regeneration and Immortal sets work best on primary supports to provide steady self-healing. Defiant and Perception sets supply damage mitigation and needed Accuracy for debuffers and damage dealers.
Step-by-Step Fight Execution
Manual skill control is recommended to prevent wiping during form transitions.
- Lock down Form 1: Open the battle by applying Block Buffs and Decrease Defense to Amius before he takes a turn. This prevents his shield and Counterattack buffs from appearing. Apply Leech to sustain your team through regular attacks.
- Deal damage safely: Attack Amius while Block Buffs remains active. Hold your major defensive cooldowns when the boss's Turn Meter indicates an impending form shift.
- Wait through the transformation: Amius cleanses all debuffs as he enters Form 2. Do not spend debuff skills until his transformation animation finishes and he is fully targetable in his new phase.
- Debuff Form 2 immediately: On your fastest champion's turn in Form 2, apply Decrease Attack and Heal Reduction. Decrease Attack prevents his follow-up AoE from wiping champions below 3,500 Defense, while Heal Reduction negates his recovery.
- Cycle back to Form 1: Whittle down his health while monitoring the phase shift. Hold your Block Buffs skill so it is ready to cast the exact turn Amius reverts to his primary form.

This saved me time in the early game.

I tried this today and it worked better than my old setup.
Nice guide. I am checking the other RAID: Shadow Legends articles next.
