This complete Arms of God all bosses guide covers the strategies for all 11 major bosses, including the secret final encounter and the New Game+ exclusive challenge. The key to victory is mastering the 'Resonance' parry system and exploiting each boss's unique elemental weakness, which often shifts dramatically between their two or three phases. Forget everything you learned in other soulslikes; aggression and perfect parries are rewarded here more than passive dodging.

Below you'll find the full boss order, detailed strategies for each fight, their weaknesses, and the unique rewards they drop. We've structured this to take you from your first tentative steps in the Shattered Chantry to your final confrontation with the cosmos itself.

Essential Preparations: Your Pre-Fight Checklist

Before you challenge the demigods holding the titular Arms of God, you need to understand the core mechanics they are built to test. Rushing into a boss arena under-equipped is a recipe for frustration. Focus on these three areas before every major fight.

  • Master the Resonance Parry: Unlike a standard parry, Resonance requires you to tap the block button just as an attack is about to land. A successful Resonance parry not only negates all damage but also builds your 'Celestial Ire' meter significantly and leaves the attacker open for a devastating riposte. Most bosses have at least one key attack designed to be parried. Your goal is to identify that one move and master its timing.
  • Understand Elemental Affinities: There are three core damage types: Solar (Fire/Light), Abyssal (Dark/Void), and Kinetic (Physical). Most bosses have a clear weakness and a strong resistance. Applying weapon greases like 'Sun-Ash Balm' or 'Void-Tallow' before a fight is often the difference between a ten-minute slog and a two-minute execution. Check your Bestiary after a first attempt to see revealed resistances.
  • Upgrade Your 'God-Vessel': Your healing flask, the God-Vessel, can be upgraded in two ways. 'Sainted Glass Shards' increase the number of uses you have, while 'Hallowed Ichor' improves the amount of health each use restores. Prioritize finding these items in the world; a fully upgraded Vessel is more important than a slightly stronger weapon.

The First Hurdles: Early-Game Aberrations

Your initial journey will test your grasp of basic combat. These first three bosses are designed to teach you fundamental lessons about aggression, crowd control, and environmental awareness.

1. The First Scribe

Found at the end of the Shattered Chantry, this robed figure seems frail but wields a massive, rune-etched quill. The First Scribe is your introduction to the Resonance parry system.

  • Strategy: Stay close and be aggressive. Its most dangerous attack is a long-range ink projectile that is difficult to dodge. By staying in its face, you bait out its slow, sweeping quill attacks. These are heavily telegraphed and perfect for practicing your Resonance parry. After three successful parries, the Scribe will be staggered, leaving its head vulnerable for a massive damage window. Do not let it create distance.
  • Weakness: Abyssal.
  • Reward: Scribe's Runic Quill (Spear), Tome of Whispers (Lore Item).

2. The Gilded Warden

This towering suit of armor guards the entrance to the Basilica of Veils. It's a classic gear check, designed to punish players who haven't upgraded their weapons or learned to manage their stamina bar.

  • Strategy: The Warden is slow but hits like a truck. Its attacks have massive area-of-effect (AoE) shockwaves, so dodging away is often a trap. The key is to dodge through its horizontal swings to end up behind it. It has a long recovery animation after its shield slam combo, giving you ample time for 2-3 hits. In its second phase (below 50% health), its armor will glow, and it will add a Solar-based beam attack. This beam is its biggest opening; as it charges, sprint to its side for a free damage window.
  • Weakness: Kinetic (Strike).
  • Reward: Warden's Soul, unlocks weapon enchanting.

3. The Hungering Chorus

Located in the flooded Ossuary, this is not a single entity but a swarm of smaller, robed figures that coalesce into larger forms. This fight is a test of crowd control and target prioritization.

  • Strategy: The fight starts with about a dozen 'Whisperers'. They are weak individually but can overwhelm you. Use wide, sweeping attacks to thin the herd. After defeating enough of them, they will merge into a single, large 'Choral Knight'. This knight inherits the swarm's aggression but is much slower. Its primary weakness is its back, where the souls are visibly swirling. When the Knight is defeated, it shatters back into a smaller group of Whisperers. You will repeat this cycle three times. Focus on clearing the small fries quickly to minimize the time you're fighting on multiple fronts.
  • Weakness: Solar.
  • Reward: Chorus Bell Charm (Talisman that pulses AoE damage).

The Great Filter: Mid-Game Horrors

This is where Arms of God truly begins. The next set of bosses introduces complex mechanics, multi-phase movesets, and require a deep understanding of the game's systems.

4. The Abyssal Lector

This cloaked sorcerer resides at the apex of the Grand Archives. The fight is less about reflexes and more about pattern recognition, as the Lector floods the arena with Abyssal magic.

  • Strategy: The Lector itself barely moves. It summons three types of projectiles: slow-moving homing orbs, fast-moving straight bolts, and a massive AoE explosion centered on itself. The key is to constantly be moving and to use the pillars in the library to block the bolts. The homing orbs can be destroyed with a single quick attack. The opening to attack the Lector comes after it unleashes its AoE explosion, which has a long charge time. Rush in, get a few hits, and retreat before the next volley begins. Patience is your greatest weapon here.
  • Weakness: Solar.
  • Reward: Staff of the Void, unlocks Abyssal Sorcery.

5. The Shattered Astrolabe

This is a puzzle boss found in the Orrery of Worlds. The boss is a massive, rotating gyroscopic device in the center of a circular arena. It cannot be damaged directly.

  • Strategy: The Astrolabe itself only emits pulsing energy waves you must jump over. To win, you must activate four runes on the arena's perimeter. Each rune is guarded by a different type of ethereal guardian (a swordsman, an archer, a mage). You must defeat the guardian next to its rune, which then gives you a 10-second window to run to the rune and perform a channel action. While you channel, the Astrolabe will fire a targeted energy beam at you. You have to time your channel to finish just before the beam hits. Activating all four runes shatters the device.

6. The Twin Sentinels, Lumen & Umbra

Guarding the path to the Celestial Spire, this is the game's mandatory dual boss fight. Lumen is a fast, aggressive knight wielding a Solar spear, while Umbra is a more defensive caster who uses Abyssal magic.

  • Strategy: Your success depends entirely on separating them. Use the large pillars to break their line of sight. Lumen is the primary threat; focus on taking him down first. He is extremely vulnerable to Resonance parries. Umbra will hang back and cast spells, but if you get too close, she will teleport away. Once Lumen is defeated, Umbra becomes much more aggressive, imbuing her daggers with Abyssal energy. Her attacks are fast but poorly tracked, making them easy to dodge if you stay calm. Never let them corner you together.
  • Weakness: Lumen is weak to Abyssal; Umbra is weak to Solar.
  • Reward: Blade of Dawn & Blade of Dusk (Paired Swords).

The Final Reckoning: Endgame Architects

These are the beings who hold the fate of the world in their hands. Expect multi-phase, cinematic battles that will test every skill you've acquired.

7. The Forlorn Progenitor

At the base of the great tree in the Ashen Garden, you'll find this massive, beast-like entity. It's a pure test of endurance and recognizing slow, but devastatingly powerful, attack patterns.

  • Strategy: The Progenitor's attacks are slow but have incredible range and tracking. The safest place is directly under its legs. From here, you can avoid most of its swipes and slams. Its most dangerous move is a ground pound that sends roots erupting from the floor, which you must run away from. In phase two, it will begin crying a golden sap that creates damaging puddles on the ground, restricting the arena space. This is when you need to be precise, luring it away from the puddles to create safe zones to fight in.
  • Weakness: Abyssal.
  • Reward: Seed of the World-Tree (major God-Vessel upgrade).

8. The Eye of the Firmament

This is the final story boss for the standard ending. Fought on a celestial plane, this cosmic eye attacks with beams of light and summons crystalline minions.

  • Strategy: The Eye itself is the target. It will periodically teleport around the arena. Its main attacks are a sweeping laser and a volley of light shards. Both are dodged by rolling forward, through the attack. After it attacks, it will remain still for a few seconds, which is your damage window. It will also summon 'Crystal Sentients'; you must destroy these quickly, as they will heal the Eye if left alive. Prioritize the adds above all else.
  • Weakness: Kinetic (Thrust).
  • Reward: Access to the game's standard ending.

Secret & Optional Bosses

For those who seek to unravel all of the game's mysteries, two final challenges await.

9. The Final Emanation (True Final Boss)

To fight this boss, you must first gather the three 'Fragments of Truth' before defeating the Eye of the Firmament. This will give you a different post-fight cutscene and transport you to a new arena: The Nexus.

  • Strategy: This humanoid boss is incredibly fast and uses attacks inspired by all the previous bosses. Phase one is a duel where you must master Resonance parries. Phase two begins at 60% health, where the Emanation sprouts four large, ethereal wings. Each wing can act independently, firing projectiles or swiping at you, while the main body continues its assault. The key is to focus damage on a single wing until it is destroyed, which will briefly stagger the boss. Destroying all four wings initiates phase three, where the boss is much slower but its attacks deal massive damage. It's a battle of attrition.
  • Weakness: None. It has neutral resistance to all damage types.
  • Reward: Access to the true ending, 'The Age of Silence'.

10. The Silent Cartographer (Optional)

This secret boss is found by presenting the 'Map of the Unseen' to the statue in the Grand Archives. The Cartographer is a master of misdirection, creating illusory clones and teleporting constantly.

  • Strategy: The Cartographer splits into three identical copies. Only one is real; hitting a clone will cause it to explode, dealing heavy damage. The real one can be identified by the faint golden glow around its feet. You must land a single hit on the real one, which causes all three to vanish and reappear in new positions. After three successful hits, the clones disappear, and the real Cartographer will fight you one-on-one. He is extremely fast but has low health. A single stagger is usually enough to finish him off.
  • Weakness: Solar.
  • Reward: Cartographer's Compass (Talisman that reveals illusory walls).

11. Echo of the Founder (New Game+)

In New Game+, returning to the arena where you fought the First Scribe will trigger a new fight against a spectral, prime version of that boss.

  • Strategy: The Echo uses a vastly expanded moveset, including Abyssal sorceries and a devastating grab attack. Its quill attacks are now much faster and have deceptive timing, making Resonance parries extremely difficult. This is purely a challenge for series veterans, testing your mastery of all mechanics. Be prepared to die, a lot.
  • Weakness: Solar.
  • Reward: Founder's Regalia (Armor Set).
