Exploring the underground can be very rewarding. From uncovering ancient relics or long-forgotten secrets to discovering a massive vein of Scarlet Ore, there are lots of reasons youll want to comb through every inch of the map. Of course, the underground is not without its dangers. Youll definitely want to keep an eye out for the monsters weve mentioned so far in our Creature Compendium (part one and part two!), but there are also some bigger threats youll need to watch out for in the form of our many bosses! Read on for information that might just save your life when you find yourself up against

Glurch the Abominous Mass

What is it? A giant Slime! Where is it? Youll find this vibrant orange creature somewhere in the Dirt Biome. Fun Fact: We came up with the design for Glurch when we were considering what would happen if lots of our Orange Slimes fused together.

About Glurch

One of the first enemies we added into the game were the Slimes, so it made a lot of sense that one of the first bosses you encounter in the game would be a slime boss! Youll know youre getting close to Glurch because youll see the screen shaking and hear the sounds of him jumping as you approach. Like most of our bosses, Glurch is pretty big, and he can be a bit of a challenge at first. We recommend wearing some form of armour and bringing along some cooked food for health and speed buffs if possible. Glurch attacks by jumping onto and crushing the player, so you should keep an eye on his attack pattern and time your strikes in between jumps.

Ghorm the Devourer

What is it? A huge insect! Where is it? Always on the move, youll find Ghorm following a circuit that runs through the Dirt Biome and the Clay Caves. Fun Fact: Ghorm was inspired by the insects from the Studio Ghibli Film Nausica of the Valley of the Wind.

About Ghorm

Youll spot lots of larva creatures in the Clay Caves, but Ghorm is by far the largest larva in Core Keeper. Ghorm travels through the underground with little regard for the structures or creatures in its path. Despite its destructive tendencies, Ghorm is actually passive, only attacking if provoked. Defeating this behemoth can be a bit tricky almost like a puzzle since you need to keep it within range of your attacks. There are a couple of ways you can do this, from setting traps and bombs all the way to buffing yourself so that you can keep up. Make sure youre prepared when you do decide to pick a fight, as Ghorm is a formidable enemy who will chase you for quite some time once engaged in combat.

The Hive Mother

What is it? Were not entirely sure, but it keeps having babies! Where is it? The Hive Mother is lurking deep within the Clay Caves. Fun Fact: The Hive Mother is entirely static, meaning that it cannot move across the map.

About The Hive Mother:

The Hive Mother is a very unique organism that could quite possibly be the source of all life in the Clay Caves. This creature is rooted to the ground and seems to spend all of its time spawning larva, which will protect the Hive Mother with their lives. Like Ghorm, the Hive Mother will not attack unless provoked, but it's important to make sure youre prepared for this boss battle! Whilst The Hive Mother cannot move, it boasts a deadly ranged attack, spewing acid slime targeted directly at any attackers. You wont just be dealing with The Hive Mother in this battle, as it will continue to spawn babies that will attack you continuously for the duration of the fight. Keep your wits about you, or you might just find yourself overwhelmed as the chamber you are in fills with acid and enemies! We recommend high-level armour, lots of healing potions, and possibly even taking on this boss as part of a team if you can.
Thats it for part one of our boss guide. Have you come face-to-face with any of the monsters in this Steam post, and if so, which did you find the most challenging to defeat?
