 *"A gelatinous singularity that has consumed many universes in its wake..."*

**Astrageldon** (Japanese: アストラゲルドン *Asutoragerudon*) was a Hardmode Superboss that has been replaced by Astrum Aureus. It took the appearance of a gigantic slime infected with the Astral Blight with a slew of different unnatural abilities.

## Spawn

Astrageldon was summoned by using the Astral Communicator dropped by Ascended Astral Slimes in the Astral Infection before defeating the Moon Lord. If Astrageldon's first phase had been defeated prior, the item would automatically summon it in its second phase, with its first phase becoming spawnable through its alternate function.

* If Astrageldon had been defeated prior, it could be resummoned after defeating the Moon Lord.
* With the Calamity's Vanities mod enabled, the item could also be used in the mod's artificial Astral Blight biome.

## Behavior

Astrageldon behaved similarly to most Slimes and attempted to leap towards the player. Its damage, defense, movement speed and firing speed increased significantly as its health lowered. Astrageldon itself was massive, roughly twice as big as King Slime. Like King Slime, it would teleport near the player if they got too far away.

### Attacks

* Periodically teleported into the air above the player in an attempt to crush them.
* Fired eight fireballs of varying speeds in a symmetrical, star-like shape.
* Attempted to shoot fireballs directly at the player, and fired faster as its health decreases.
* Spawned Astral Slimes as it took damage.

### In Revengeance Mode

* Phase 1 health increased to 200,000. Phase 2 health increased to 336,000.
* Damage increased to 246.
* Had time-based damage reactive damage reduction in phase 2.
* Phase 1 gained a new attack which occurred after its Nova Slime rain where Astrageldon would jump, fire a floral pattern of stars, then slam downwards while chasing the player. This occurred three times before transitioning to its Asteroid Belt attack.
* Shockwaves travelled an extra 10% longer.
* Phase 1 slams spawned rocks upon reaching 50% life instead of 40%.
* Fired 1 extra Nebula Residue Mine every time it shot for a total of 6 Mines.

### In Death Mode

Damage increased to 275.

* Shockwaves travelled an extra 10% longer.
* Phase 1 laser attacks shot out 12 spokes of lasers instead of 10.
* Summoned 1 more Nova Slime per wave.
* Slams created rocks upon reaching 75% life instead of 50%.
* Summoned an additional pair of Nova Slimers on subsequent waves for a total of 10 pairs.

## Notes

* While Astrageldon was alive, the following events would be disabled:
	+ Rain
	+ Slime Rain
	+ Parties
	+ Sandstorms
* The lock on spawning Astrageldon was indicated by a status message, meaning that dying to the Moon Lord would not cause the boss to become locked off.
	+ This meant that the player could clear the Lunar Events then die to the Moon Lord if they wished to fight the boss without any pillars active.

## Aftermath

* Spiral clusters of Metanova Ore would generate in the underground Astral Infection.
* Nova Slimes would start spawning on the surface Astral Infection.
* Metanova Slimes would start spawning in the Cavern.
* The Astrageldon Style menu theme would be unlocked.

## Tips

* Due to the use of Interstellar Corruption in the fight, the Rod of Discord should not be relied on as the debuff would instantly kill players inflicted by it, unless the player could avoid the Nova Slimers and the bordering arena.
* The Astral Communicator becomes unusable after defeating the Moon Lord, meaning players shouldn't wait to fight the boss with stronger gear as it would become inaccessible.
* Running away from the waves of Nova Slimes was more advisable than attempting to kill all of them as they could become overwhelming to kill while also avoiding the boss.
* Baiting Astrageldon into dashing across the border of the arena then flying to the opposite side during its grid mine attack could be a useful alternate strategy as it left most of the mines unable to hit the player, though this method was not reliable and the player should be prepared to wedge into a safe spot if an unlucky pattern occurred.

## Trivia

* Astrageldon's phase 1 theme was **Cosmic Disgust**, which was composed by the artist DM DOKURO.
	+ This theme's introduction contains a motif from The Slime God's theme.
* Before Astrageldon's final phase initiated, its theme switched to **Galactic Destruction**, which was composed by the artist Heart Plus Up!
	+ If the Calamity Music add-on mod was disabled, the Moon Lord's theme would play instead.
* Astrageldon was a "**Superboss**" in this mod. In some RPG games, Superbosses are extremely powerful enemies that are very challenging even if the player has endgame equipment.
	+ It shared this trait with Adult Eidolon Wyrm, Vision of the Tyrant, The Entropic God, Noxus and THE LORDE.
	+ Astrageldon was the only Hardmode Superboss to ever be added to the Calamity mod.
* Like Armageddon, it was a reference to the Armageddon Slime from the Exxo Avalon mod.
* Its name was a portmanteau of the words *astral*, *armageddon* and *gel*.
* If the Boss Checklist Mod was installed, its unique despawn message would be "The multiversal terror returns to its consumption."
* Astrageldon is speculated to have been removed due to being too high in quality for the Calamity mod.
