The **Astrageldon Slime** is a Hardmode boss that replaces Astrum Aureus once you defeat the Eye of the Universe in Impossible Mode. Defeating it causes a Void Meteor to fall somewhere in the world.

After defeating the Supreme Pro Calamitas , the Astrageldon Slime beings dropping Loose Fabrics of Reality.

== Spawn ==
The Astrageldon Slime can be summoned at Night using the Astral Chunk after the death of the Eye of the Universe. Despite being connected to the Astral Infection biome, it can be summoned anywhere.

== Behavior ==
Astrageldon Slime behaves similarly to most Slimes and attemptsto leap towards the player. Its damage, defense, movement speed and firing speed increased significantly as its health lowers. The Astrageldon Slime itself is massive, roughly twice as big as Astrum Aureus. Like King Slime, it teleports near the player if the player got too far away. After taking enough damage, the Astrageldon Slime will puff up and gain a Dungeon Guardian-like AI and constantly spew out a barrage of projectiles.

=== Attacks ===
\* Periodically teleports into the air above the player in an attempt to crush them.
\* Fires eight fireballs of varying speeds in a symmetrical, star-like shape.
\* Attempts to shoot fireballs directly at the player, and it fires faster as its health decreases.
\* Spawns Astral Slimes as it takes damage.

Phase 2

* Charges at the player while spinning and vibrating rapidly.
* Spins in a manner similar to the Ice Queen and vomits out instakill projectiles everywhere
* Shoots giant laser beams in amounts that rival Fargo's Mutant Boss (Boss)
* Summons Astrum Aureuses as it takes damage.
* When at 5% health a countdown starts, and if you can't kill the Astrageldon Slime on time, it will explode and instakill you and any nearby NPCs without dropping loot.

=== In Impossible Mode ===
\* Once Supreme Pro Calamitas is defeated, the Astrageldon Slime will summon a clone of itself at 50% health that cannot be killed.

=== Summons ===
Astral Slimes when damaged (Phase 1)
Astrum Aureuses when damaged (Phase 2)
Astrageldon Slime (Clone) (Phase 2, post-Supreme Pro Calamitas)

== Notes ==
\* Straying too far from it (such as flying to high altitudes) in phase 1 will cause it to despawn, as it can't properly teleport to the player.
\* Astrageldon Slime can instantly kill the player at all times in Phase 2, so players should proceed with caution.

== Aftermath ==
\* Once defeated, a Void Meteor falls down into a random location in your world.

== Tips ==
\* It is recommended to use Celestial Tracers to avoid the bosses' quick attacks, and to have some sort of triple or quadruple-jump accessory to dodge the boss itself.
\* The Adrenaline Meter is easier to build up while fighting Astrageldon Slime, as you have to no-hit it anyways.

== Trivia ==
\* Astrageldon Slime's theme was Cosmic Disgust https://www.youtube.com/watch?v=ibFdltiLuKM, which was composed by the artist DM DOKURO.
\*\*This theme's introduction contains a motif from the Slime God's theme.
\*Like Armageddon, it is a reference to the Armageddon Slime from the Exxo Avalon Mod.
\* Its name is a portmanteau of the words *astral*, *armageddon* and *gel*.
\* Although it was a boss and is treated as such, the Astrageldon Slime has no Boss Mask drop.
