Astrageldon Slime

"A titanic slime infected by a star-borne disease..."

The Astrageldon Slime was a Hardmode boss that has been replaced by Astrum Aureus. Defeating it caused an Astral Meteor to fall somewhere in the world.

After defeating the Moon Lord, the Astrageldon Slime began to drop Lunar Fragments. Additionally in Revengeance Mode or Death Mode, the Astrageldon Slime increased substantially in difficulty, increasing health and damage, and began to drop the Suspicious Looking Jelly Bean.

Spawn
The Astrageldon Slime could be summoned at Night using the Astral Chunk. Despite being connected to the Astral Meteor biome, it could be summoned anywhere.

Behavior
Astrageldon Slime 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. The Astrageldon Slime itself was massive, roughly twice as big as King Slime. Like King Slime, it'd teleport near the player if the player 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 it fired faster as its health decreases.
 * Spawned Astral Slimes as it took damage.

In Revengeance Mode

 * Once the Moon Lord was defeated, the Astrageldon Slime became significantly more difficult.

Aftermath

 * Once defeated, the Wizard would begin selling Astral Chunks.

Tips

 * It was recommended to use Angel Treads 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 was easier to build up while fighting Astrageldon Slime, as its attacks were very predictable.

Trivia

 * Astrageldon Slime's 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.
 * 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.
 * Although it was a boss and was treated as such, the Astrageldon Slime had no Boss Mask drop.
