Eye of Cthulhu
❤️: 300
⚔️: 3 (phase 1), 6 (phase 2)
🛡️: 5 (phase 1), 0 (phase 2)
Size: 1.53 x 1.53

Spawning

The Eye of Cthulhu can be summoned manually using a suspicious looking eye at night (day tick 12542, or 6:32 PM according to a watch) in the overworld. Only one can be summoned at a time. It also has a 1/3 (33.33%) chance of spawning naturally each night if the following conditions apply:

• The player has not yet defeated the Eye of Cthulhu.
• The player has at least 10 armor points

if spawning naturally, its arrival is announced by the status message "You feel an evil presence watching you...". The Eye of Cthulhu spawns exactly 90 seconds after this status message was displayed. If the player is underneath any block or in a dimension other than the Overworld, the Eye of Cthulhu will not spawn.

Behavior

The Eye of Cthulhu has two phases. During the first, it attempts to float directly above the player while spawning 3 Servants of Cthulhu, maximum of 5. Afterward, it charges at the player three times in succession, before repeating the cycle.

When the Eye of Cthulhu falls below 50% (150 ❤️), it spins in place and transforms into its second form. The Eye has two attacks in this phase, one which rams the player more aggressively three times, and another where it does an extended dash that also spawns 2 Servants of Cthulhu. The Eye of Cthulhu hangs in the air for a period between each attack. Its contact damage increases from 3 to 6 but armor reduces to 0. It also now lets out a roar every time it charges.

If the Eye of Cthulhu is not defeated by dawn (day tick 23460, or 5:27 AM according to a watch), if all players die, or if it gets too far away, it will fly up and despawn.

Tips

• The Eye of Cthulhu treasure bag will drop demonite or crimtane depending on which side of the world you are on.
• Unlike its Terraria counterpart The Eye of Cthulhu cannot go through blocks (but can destroy them). This makes it highly cheesable.
• After The Eye's triple dashes, it will linger in place for a small amount of time unable to do damage. Use this time to use melee weapons.

King Slime

Overview

King Slime is one of the first bosses you can fight. It can spawn from completing a slime rain event or be summoned through a slime crown. While King Slime is alive, a noteblock remix of Gelatinous Dynasty will play.

⚔️: 4
🛡️: 0
Size: all of them

Spawning

King slime can be manually spawned with a slime crown in any biome or dimension. Only one can be summoned at a time. King slime will also spawn during a slime rain once 40 slimes from the event are killed. You can tell if a slime is from the event when hearing a pling when killing it. The spawning of King Slime immediately ends the slime rain.

Behavior

King slime will make 4 small jumps and 1 large jump towards the player. Additionally he will teleport every 20 seconds onto the nearest player, or every 10 seconds if a player is too far away.

At 50% (150 ❤️ ) health, King Slime will spawn a Crown Jewel to target the player.

As King Slime takes damage, he spawns additional Blue Slimes and Spiked Slimes and appears to shrink in size.

Achievements/Advancements

Tips

• He will stop spawning slimes if there are 8 or more Blue Slimes nearby

Desert Scourge

Overview

Desert Scourge is a worm like boss fought in the desert. It is summoned with a Desert Medallion in a desert. While Desert Scourge is alive, a noteblock remix of Guardian of the Former Seas will play

Desert Scourge
❤️: 200
⚔️: 8 (head), 4 (body)
🛡️: 0
Size: 1.95 x 2.2, 20 Segments

Spawning (more specific and per biome)

Desert Scourge can be summoned manually using a desert medallion in any desert or badlands biome. Only one can be summoned at a time. When summoned, 2 Desert Nuisances will spawn alongside the boss. Desert Scourge will spawn 20 blocks beneath you.

Behavior

Desert Scourge will burrow through blocks* at a constant speed to reach you. You can tell where it is underground by the sounds it makes and particles that will appear on the ground if the Desert Scourge is less then 25 blocks under the floor. When it gets close, its mouth will visibly open.

Every time Desert Scourge is damaged it will gain resistance 2 for a few seconds

Upon reaching 50% health, Desert Scourge will occasionally roar and lunge out of the ground, creating a circular burst of 50 damaging sand at the apex of the lunge.

*Desert Scourge can also burrow through water and the void below and above the world. It can also burrow through lava, but is not immune to it.

Achievements/Advancements

Tips & Trivia

• Finding any weapon that does piercing damage will make this boss trivial.
• The sand that the Desert Scourge spits is unlikely to hit you.

Trivia

• The current Desert Scourge model is based off of the Desert Scourge sprite by HeartPlusUp, but the AI is still based off of Desert Scourge before the resprite.
• Desert Scourge was the first feature added to this datapack.
• The Eye of Cthulhu wont leave at dawn if it is raining. This is a bug.
