Core Keeperlets you build a grand base complete with several automated processes, but along the way, you will also need to fight a boss or two. The game has several bosses, both required to progress and optional, giving you tough challenges to prepare for and overcome.

It’s possible to see several of the game’s bosses out of order, but what is the main ‘order’ recommended for defeating the bosses of Core Keeper? Here, we are going to answer just that. This list will cover every boss in order, as well as some information as to where you can find each one.

1Glurch The Abominous Mass

First up, we have Glurch The Abominous Mass. This giant slime ismeant to be the first boss that you face, and is found relatively close to the Core; just 65 tiles! As such, you should quickly be able to find Glurch.

To take him out, we suggest keeping your distance and using ranged weapons. Be cautious of the ground though, as walking through orange slime will slow you down. Overall, this fight should go smoothly if you have some armor and a ranged weapon.

2Ghorm The Devourer

Ghorm The Devourer is a unique boss who isconstantly on the move. If you’ve defeated Glurch and opted for the Ghorm tracker, you can see this boss moves very quickly in a circle around the Core, passing through the Clay Caves and Forgotten Ruins.

Simply attacking Ghorm will do nothing at first. Instead, you will need to do enough damage until he notices you, which means that his health will need to be at least 80 percent. This can be done with bombs and spike traps. Once at 80 percent, you can face him head-on.

3King Slime

Fans of Terraria may recognize this giant mass. King Slime is a crossover boss that you have the option to defeat. Rather than just appearing in the world though, you will need to summon him. This can be done with a Crown Summoning Idol placed on a slime summoning rune.

King Slime doesn’t bring anything too extraordinary to the table in terms of combat. He will jump around and deal damage while also summoning smaller slimes.

4Malugaz The Corrupted

Next, we have Malugaz the Corrupted. This is a giant Caveling boss can be found in the Forgotten Ruins, but you will first need to summon him. To do so, you’ll need to find the Caveling Throne Room and place a Skull of the Corrumed Shaman.

This is an item that can be made by combining three Crystal Skull Shards, which can drop from normal Cavelings. Before taking on Malugaz, be sure to clear out any enemies nearby.

5The Hive Mother

The Hive Mother is agrotesque boss that remains stationary. While this does mean that you can run around without fear of being squished, the boss will also summon larvae that can become overwhelming if you don’t take care of them.

This boss is found in the Larva Hive biome, which is very recognizable due to the flesh-like blocks. The Hive Mother is the only boss here, so you’ll know you’re near when you enter a strangely large clearing (which is her area).

6Azeos The Sky Titan

Azeos the Sky Titan is agiant flying bossthat can be found in Azeos' Wilderness. This biome is very green and grassy, serving as an outer layer biome. Here, you’re able to find two bosses, with Azeos being the only required one.

This boss can be a bit troublesome to deal with, especially due to his range of thunder attacks. Additionally, in order to summon Azeos the Sky Titan, you will need to place a Large Shiny Glimmering Object within the boss' arena.

7Ivy The Poisonous Mass

Ivy the Poisonous Mass is the second optional boss found on our list, who is also found in Azeos' Wilderness. Like Glurch, the area surrounding this boss will have slime everywhere, slowing you down.

Another similarity to Glurch is the movement; Ivy will leap around and deal damage, but this boss has the addition of poisonous projectiles that may rain down upon you. What’s more, smaller poisonous slimes may be summoned.

8Omoroth The Sea Titan

Omoroth the Sea Titan is another boss that willfirst need to be summoned before it appears. To make Omoroth the Sea Titan spawn, you will need to fish with an Expert Lurew within a whirlpool found in the Sunken Sea biome.

These are found within Omoroth’s arena, but he won’t actually appear until you fish him up. It’s worth noting that this boss will summon whirlwinds and tentacles, which can do a lot of damage. The tentacles themselves only deal melee damage, so be sure not to get too close.

An image of Morpha the Aquatic Mass from Core Keeper.

9Morpha The Aquatic Mass

This is the third boss on our list that looks like a giant, bubbly slime. Like Ivy the Poisonous Mass,Morpha the Aquatic Mass is also optional. If you do feel like taking on Morpha though, head to the Sunken Sea biome.

Like Glurch and Ivy, the arena of this boss will be covered in slime that can slow you down. Additionally, Morpha leaves behind slime where it jumps, so this is an added danger. It’s also important to keep in mind that Morpha is very quick.

An image of Ra-Akar the Sand Titan from Core Keeper.

10Ra-Akar The Sand Titan

To find Ra-Akar the Sand Titan, you’ll need to venture into the Desert of Beginnings. Here, you can summon Ra-Akar by placing a Thumper in its den. While fighting Ra-Akar, you’ll need to deal with burrowing, whirlpools, glowing orbs that target you, and summoned scarabs that will attack you.

Overall, Ra-Akar the Sand Titan can be quite challenging if you aren’t prepared. We highly suggest increasing your speed while having good armor. You’ll end up taking some damage during this fight, but with high defense, you should be fine.
