What are Titan Souls in Core Keeper?

Six souls dropped by the major Titan bosses — Azeos, Omoroth, Ra-Akar and the three Hydras (Crydra, Druidra, Pyrdra). Collecting all six lets you summon the Core Commander by shattering the Crystal Meteorite, which is the climax of the main story.

Which direction are Core Keeper bosses from The Core?

There's no fixed compass direction — Core Keeper worlds are procedurally generated, so each biome spawns at a random angle around The Core every world. The game itself tells you the direction in-world ("the desert can be found to the…"). Use the distances from The Core as your reliable anchor, not north/south/east/west.

Q: What order do you fight Core Keeper bosses in?

Start with the three statue bosses — Glurch, Ghorm and the Hive Mother — whose essences power The Core and open The Great Wall. Then work through the Titans (Azeos, then Omoroth, Ra-Akar and the three Hydras) to collect all six Titan Souls, which let you summon the Core Commander, the main-story boss. After that comes the Void & Voltage endgame: Urschleim, S.A.H.A.B.A.R. and Oblidra the Void Lord.

Q: How many bosses are in Core Keeper?

Around 18 progression bosses as of the v1.2 Void & Voltage update, plus a couple of optional non-progression bosses (the Atlantean Worm and a King Slime Terraria crossover). The exact headline number varies between guides (17 vs 18) depending on how the optional and crossover bosses are counted.

How Core Keeper's Boss Progression Works

Core Keeper's bosses come in three waves, each one gating the next:

The statue trio — Glurch, Ghorm and the Hive Mother. Their essences power The Core's three statues, which open The Great Wall and let you leave the starting band.
The six Titans — Azeos, Omoroth, Ra-Akar and the three Hydras each drop a Titan Soul. Collect all six to summon the Core Commander, the main-story climax.
The Void & Voltage endgame — past the story, Breaker's Reach holds S.A.H.A.B.A.R. and Oblidra the Void Lord, the current toughest fight.

Directions are per-world, not fixed. Core Keeper worlds are procedurally generated — biomes spawn at a random angle around The Core each time. The game tells you the direction in-world; the distances below are your reliable anchor, the compass points are not.
