Mastering Amius the Lunar Archon: Strategies for Cursed City Success

Nov 07, 2026•FastAccess Team•4 min read

Conquering the Lunar Archon

Amius the Lunar Archon serves as the ultimate challenge within the Cursed City of Sintranos. To reach this boss, players must navigate through various stages and collect three Eclipse Keys by defeating specific Double Boss encounters across the four districts.

Once unlocked, Amius presents a complex battle involving two distinct forms, each with unique skills and punishing mechanics. Success requires careful team composition, precise timing, and a deep understanding of his transformation triggers.

Navigating the Base Form

In his Base Form, Amius utilizes skills that reward him for having active buffs and punish teams that rely on excessive debuffs. His primary threats include:

  • Waxing Potence: An AOE attack that grows stronger based on the number of buffs Amius possesses. He heals for 100% of the damage dealt, making Heal Reduction essential.
  • Lunar Storm: This skill extends his buffs, shortens your debuffs, and grants him massive healing and Turn Meter boosts.
  • Rampant Chaos: A dangerous ability that converts your debuffs into mirrored buffs for the boss. For instance, Decrease ATK becomes Increase ATK, and Heal Reduction turns into Continuous Heal.

The passive ability Robed in Moonlight allows Amius to heal whenever your team receives healing and accelerates his transformation if your team uses any form of cooldown manipulation. Avoid unnecessary cooldown resets to maintain control over his skill cycle.

Surviving the Alternate Form

When Amius enters his Alternate Form, the encounter shifts toward high-impact damage and debuff manipulation. His most critical mechanics are:

  • Abyssal Construct: Targets the ally with the lowest HP, ignoring 100% of their DEF. Using a dedicated tank with high Awakening levels is vital to mitigate this damage.
  • Bloodmoon Vortex: An AOE attack that manipulates buff and debuff durations while scaling damage based on the targets' MAX HP.
  • Maniacal Bedlam: Converts your positive buffs into negative debuffs and inflicts an unblockable Sleep on all non-Mythical Champions.

During this phase, the Scarlet Eclipse passive reduces your incoming healing by 50% and allows the boss to ignore defensive buffs like Shield and Unkillable. Furthermore, any cooldown reduction on your team will trigger an immediate Abyssal Construct attack.

Key Strategic Considerations

Managing the encounter effectively requires balancing offense and defense. Because Amius possesses Almighty Immunity, he cannot be stunned, frozen, or have his Turn Meter reduced. Instead, focus on these priorities:

  • Heal Reduction: Crucial for preventing the boss from recovering health during his Base Form.
  • Block Debuffs: Essential for preventing the Stun and Sleep effects that disrupt your team’s ability to act.
  • Debuff Management: Carefully time your debuffs to avoid giving the boss powerful buffs during his conversion phases.
  • Awakening Levels: Higher Awakening levels reduce the damage Amius deals and improve your team's damage output, making them highly valuable for your tank and damage dealers.

FAQ

How do I stop Amius from reviving in his Alternate Form?

Amius revives if killed while under the Eclipse effect. You can either time your damage to finish him while he is in his Base Form or utilize a champion with a Block Revive ability to negate the effect.

Why does Amius transform sooner than expected?

His transformation is tied to the Archon’s Ascendance passive, which reduces its cooldown whenever your team uses skills, artifacts, or masteries that reduce cooldowns. Avoiding these effects helps you keep the boss in his Base Form for longer.

What is the best way to handle the Abyssal Construct attack?

Amius targets the champion with the lowest HP. Designate a high-survivability tank with a high Awakening level to absorb this hit, and consider using champions with Taunt or evasion mechanics to protect the rest of your team.

Can I control the boss's skill priority?

Yes, by managing your debuffs. If you have two or more debuffs that can be converted into buffs, he will prioritize Rampant Chaos. If you have fewer debuffs, he is more likely to use Lunar Storm. Use this to force him into more predictable patterns.
