In the Lands Between, few things are as satisfying as vaporizing a boss in seconds. With the Comet Azur spell and the right setup, you can do just that — reduce even major bosses to ashes before they can react. This guide shows you how to harness the power of Starcaller’s Wrath, a devastating build centered around Comet Azur, to one-shot bosses and Elden Ring Runes breeze through some of the game’s toughest encounters in Elden Ring.

What Is Comet Azur?

Comet Azur is a legendary Sorcery spell in Elden Ring, known for its:

Massive FP consumption

Laser beam-style damage

Insane burst potential

It unleashes a continuous beam of cosmic energy that can melt through bosses if channeled uninterrupted. When combined with specific talismans, buffs, and gear, it becomes the ultimate boss-destroying nuke.

Core Build: Starcaller’s Wrath (Comet Azur Build)

Primary Stats:

Intelligence (70+) – Maximizes spell scaling and damage

Mind (35–45) – Gives a deep FP pool to maintain the beam

Vigor (20+) – Just enough for basic survival

Endurance (base) – Not a major concern; you won’t be dodging

Required Gear:

1. Comet Azur (Spell)

Found in Mt. Gelmir by speaking to Primeval Sorcerer Azur

No boss fight needed – just travel and talk

2. Lusat’s Glintstone Staff

Best staff for raw damage, though it increases FP costs

Found in Sellia, Town of Sorcery (behind a boss)

3. Azur’s Glintstone Set

Boosts Comet Azur and other primeval sorceries

Optional but stylish and lore-appropriate

Talismans & Buffs:

Talismans:

Radagon Icon – Reduces spell cast time

Graven-Mass Talisman – Greatly boosts sorcery damage

Magic Scorpion Charm – Increases magic damage (at the cost of defense)

Godfrey Icon – Enhances charged sorceries (Comet Azur is chargeable)

Flask of Wondrous Physick:

Magic-Shrouding Cracked Tear – Boosts magic damage

Cerulean Hidden Tear – Removes all FP consumption for 10 seconds (essential!)

Optional Buffs:

Terra Magica – Spell buff circle that increases magic damage

Golden Vow/Flame, Grant Me Strength – From allies or items if running co-op/hybrid build

How to One-Shot Bosses: The Rotation

Executing this build requires timing and preparation, but the result is explosive:

Boss One-Shot Setup (Pre-fight):

Drink your Flask of Wondrous Physick (Cerulean Hidden Tear + Magic Boost)

Cast Terra Magica to create your buff zone

Line up the boss’s spawn point or entry animation

Begin charging Comet Azur just before the fight starts

Watch the boss disintegrate

Pro Tip:

If you’re running co-op or have summons, use them to distract the boss while you prepare your nuke.

This strategy works best when the boss has a lengthy intro animation or doesn't immediately aggro.

Bosses You Can One-Shot with Starcaller’s Wrath

With the right execution, these bosses can be destroyed in one cast:

Easily One-Shottable:

Magma Wyrm Makar – Slow and easily locked down

Royal Knight Loretta – Opens with a delay and is weak to magic

Godrick the Grafted – Long animation gives you time to nuke

Red Wolf of Radagon – Melts if you hit immediately on spawn

Commander Niall – Beam him before he summons his allies

Requires Distraction or Setup:

Malenia – Possible with Mimic Tear aggro, though difficult

Mogh, Lord of Blood – Weak to magic but requires timing

Dragonkin Soldiers – Highly vulnerable to ranged nukes

Not Ideal Against:

Fast/aggressive bosses like Maliketh or Radagon

Enemies with multi-phase fights unless you save the nuke for phase two

Solo vs Co-op Strategy

Solo Play:

Use Summon Ashes like Mimic Tear or Latenna to draw aggro

Always nuke when the boss is focused elsewhere

Stack FP-flask charges to retry if you fail

Co-op Play:

Let allies engage the boss first

While they tank or distract, set up your rotation

Use Terra Magica and Comet Azur for the finishing blow

Advanced Tips for Max Damage

Use Int+ gear like Marika’s Soreseal (with caution)

Over-level Mind to keep casting even if Cerulean Tear ends

Position carefully — line-of-sight interruptions will break the beam

Use Golden Order Seal + Flame, Grant Me Strength if running a hybrid build

Weaknesses of the Build

While insanely powerful, Starcaller’s Wrath has some drawbacks:

Very FP-reliant – Requires flask and Mind investment

Glass Cannon – Minimal defense and HP

Boss-dependent – Doesn’t work well on fast-moving or teleporting enemies

Setup Time – You need 5–8 seconds to properly prepare

Conclusion: Wrath from the Stars

The Starcaller’s Wrath build channels the full destructive force of the cosmos through Comet Azur, enabling you to obliterate many bosses before they land a hit. While it’s not a fit for every encounter, in the right hands and buy Elden Ring Runes with the right setup, it’s one of the most powerful and satisfying builds in all of Elden Ring.

So line up your staff, sip your glowing tears, and bring the fury of the stars down upon your enemies.

May your cast be uninterrupted, Tarnished.
