The Slime God

"It is a travesty, one of the most threatening biological terrors ever born."

The Slime God is a Pre-Hardmode boss that can be fought anywhere. The boss is comprised of three main parts, the Ebonian Slime God, the Crimulan Slime God, and the Core itself. All three will spawn upon the use of the Overloaded Sludge, regardless of whether the world generated contains Corruption or Crimson.

Spawn
The Slime God does not spawn on its own and requires the player to summon it with the Overloaded Sludge.

Behavior
The Slime God encounter is made up of three individual bosses: The Ebonian Slime God, Crimulan Slime God, and The Slime God itself. Each has its own unique behaviors and attacks.

If gravity is reversed, such as when using a Gravitation Potion, The Slime God Core will enrage, significantly increasing its movement speed.

Ebonian and Crimulan Slime Gods

 * Will jump toward the player similarly to other slimes.
 * Occasionally flies over the player and attempts to drop down directly on top of them.
 * Teleports near the player when they are at least 337.5 tiles away.
 * Quickly boost themselves towards the player when they are at least 150 tiles away.
 * Fire Abyss Ball Crimson.png at the player when they are at least 10 tiles away.
 * Ebonian Slime God fires four balls and has a shooting cooldown of seconds. If the Crimulan Slime God is defeated, this reduces to  seconds.
 * Crimulan Slime God fires two balls and has a shooting cooldown of seconds. If the Ebonian Slime God is defeated, this reduces to  seconds.
 * Spawn smaller slimes as it takes damage.
 * Ebonian Slime God spawns 1-2 every 20% of its health lost.

 * If the Crimulan Slime God is defeated, Ebonian Slime God will double its movement-based attack rates.
 * If the Ebonian Slime God is defeated, Crimulan Slime God will double its defense.

The Slime God (Core)

 * Constantly accelerates towards the player, inflicting the Distorted Debuff on hit.
 * When damaged, can rush at and enter one of the other Slime Gods, becoming invulnerable for 10 seconds. For the duration, the possessed god will gain certain boosts.
 * All possessed slimes will temporarily gain Death Mode AI.
 * Ebonian Slime God will gain damage and 20 defense.
 * Crimulan Slime God will gain damage and 24 defense.
 * Transitions into Phase 2 at 20% health. If both Crimulan and Ebonian Slime Gods have been defeated, it will transition at 40% health instead.
 * Continues to accelerate at the player at a faster pace with a higher maximum speed.
 * Continuously releases a random spread of two Abyss Ball Crimson.png as it travels.

In Expert Mode

 * Increases acceleration and speed to all slimes.
 * The Slime Gods have a 50% chance to fire Abyss Ball Crimson.png instead of Abyss Balls. Mines exponentially slow to a stop and linger in place for 50 seconds before exploding and despawning.
 * The Slime God Core and Ebonian Slime God will always fire one less mine.
 * The Ebonian and Crimulan Slime Gods will split into two smaller slimes once they reach half health. They behave similarly to the non-split gods, with some minor changes.
 * They are unable to teleport near the player when they are too far away.
 * They quickly boost themselves towards the player when they are at least 225 tiles away, instead of 150.
 * Split Ebonian Slime God will gain 40 damage and 16 defense when possessed.

 * Split Crimulan Slime God will gain 44 damage and 20 defense when possessed.
 * Split Crimulan Slime God fires one ball and has a shooting cooldown of seconds. If the Ebonian Slime God is defeated, this reduces to  seconds.

In Revengeance Mode

 * Increases acceleration and speed to all slimes, higher as their health decrease.
 * Crimulan and Ebonian Slime Gods fire Abyss Balls and Mines more frequently.
 * In Phase 2, instead of releasing projectiles at a continuous pace, the Slime God Core teleports near the player and travels in a circle while firing projectiles at the player.

In Death Mode

 * Increases acceleration and speed to all slimes, higher as their health decrease.

Aftermath

 * Once defeated, the Dryad will begin selling Overloaded Sludge.
 * The Bandit will begin selling Gel Darts.

Tips

 * Do not run too far away, or otherwise, the Slime Gods will ram the player at very high speed, making it very difficult to dodge them. Try to keep them on the screen to avoid getting hit easily.
 * Avoid the Slime God Core at all costs because the Distorted debuff it inflicts can make you easy prey for the Crimulan and Ebonian Slime Gods.
 * Using a hook or minecart track can help the player with avoiding the boss if the player gets the Distorted debuff.

Trivia

 * The Slime God's theme is Return to Slime, which was composed by the artists DM DOKURO and SixteenInMono.
 * This theme contains motifs from The Perforators and The Hive Mind's themes.
 * If the Calamity Music add-on mod is disabled, Boss 1 will play instead.
 * In the theme, a voice shouts some unknown words.
 * Unlike all the other bosses, the Slime God has 2 Masks, one for the Crimulan Slime God and another for the Ebonian Slime God. This is similar to the fact that The Twins and Calamitas have multiple different Trophies.
 * Only one of the two masks can drop at a time.
 * The Slime God was one of the first bosses added to the Calamity Mod, along with the Desert Scourge and The Devourer of Gods.
