Core Keeper Boss Progression Tracker
Complete Core Keeper boss progression tracker. All 18 bosses from Glurch in the Dirt Biome through Oblidra the Void Lord in Breaker's Reach. Progression order, HP, drops, abilities, unlocks.

Every Core Keeper boss, in the right order to fight them
Core Keeper is a progression game — each boss unlocks a new tier of gear, a new biome, or a new meta-progression. Fight out of order and you'll be underleveled with the wrong drops. This tracker lists all 18 bosses from the current Void & Voltage update (patch 1.2, February 2026) in the order community speedrunners and theorycrafters recommend.
Click the circle on any boss card to mark them defeated. A green check + strikethrough shows your progress. The top bar tracks your overall kill count + percentage. Progress saves to your browser's localStorage — come back weeks later and your hunts are still there. No account, no sign-up.
Each boss card shows the progression order number (1 Glurch → 18 Oblidra), their tier color, biome, HP (where wiki-confirmed), and expands to a full detail view: how to find them in the world, summon requirements (most bosses are wandering, but some like Malugaz need a shrine activation), their signature abilities, all notable drops, and what their defeat unlocks in the progression tree.
Boss list: Dirt trio (Glurch, Ghorm, Hive Mother) → Clay Caves (Malugaz) → Azeos' Wilderness (Azeos the Sky Titan) → Forgotten Ruins (Ivy the Poisonous Mass) → Sunken Sea (Morpha, Omoroth) → Molten Quarry (Igneous the Molten Mass) → Desert (Ra-Akar the Sand Titan) → Shimmering Frontier Hydras (Crydra / Druidra / Pyrdra / Nimruza) → The Passage (Core Commander, Urschleim) → Breaker's Reach end-game (S.A.H.A.B.A.R, Oblidra the Void Lord — both added in Void & Voltage).
If you host your own Core Keeper server on XGamingServer, this tracker doubles as a group-progress dashboard — plan raids around the next unhunted boss, verify your server has cleared gating bosses (Malugaz unlocks The Core's power, the three Titans unlock Great Wall / end-game), and target specific drops your party still needs.
Core Keeper Boss Progression Tracker — FAQ
How many bosses are in Core Keeper?
18 bosses across 5 tiers in the current Void & Voltage update (Feb 2026). Early (Dirt + Clay trio), Mid (Azeos + Malugaz + Ivy), Late (Sunken Sea + Molten Quarry + Desert Titans), Shimmering Frontier (4 Hydras), and End-game (Core Commander, Urschleim, S.A.H.A.B.A.R, Oblidra).
What order should I fight the Core Keeper bosses?
Glurch → Ghorm → Hive Mother (Dirt/Clay) → Malugaz (Clay Caves power core) → Azeos the Sky Titan → Ivy the Poisonous Mass → the three Great Titans (Morpha/Omoroth/Igneous/Ra-Akar in any order) → Shimmering Frontier Hydras → The Passage → Breaker's Reach end-game. The tool sorts in this exact order.
What's new in Void & Voltage?
Patch 1.2 (late Feb 2026) added Breaker's Reach biome, the S.A.H.A.B.A.R mech boss (summoned via Profane Override), Oblidra the Void Lord (fourth Hydra, summoned via Wind Organ of Void), and automation/conveyor stations. Nimruza's role was repurposed to gate Breaker's Reach access via Brood Void Neuron.
Are boss HP values in the tool accurate?
Where wiki-confirmed, yes — Azeos 32k, Omoroth 91k, Ra-Akar 161k, Core Commander 465k, Nimruza 228k. Some (Glurch, Ivy, Morpha, Igneous, early Hydras) use community-approximation values from corekeeperdb.com. S.A.H.A.B.A.R and Oblidra HP are not yet published — shown as 0/unknown.
Does progress save across devices?
No — progress is localStorage only, per-browser. Clearing site data wipes it. No account system keeps the tool fast + privacy-friendly. If you need cross-device sync, screenshot the list or bookmark a specific kill state.
