Core Keeper Final Boss: How to Summon and Beat the Core Commander

How to summon the final boss (Core Commander)

1. Defeat Azeos, Omoroth, Ra-Akar, Druidra, Crydra and Pyrdra to collect all six souls (soul powers).
2. Talk to the Core. It tells you to come to “the barren place far to the (direction)”.
3. Go to the crystal meteor in The Desert of Beginnings, interact with it and shatter it. The Core Commander appears after a few seconds.
4. To fight it again, place Core Commander Summoning Idol on the summoning rune left inside the meteor.

Final boss fight tips

• Three orbs shield it: three orbs circle the boss 6 to 9 tiles away, and the boss takes no damage while they are up. A destroyed orb drops to the floor and keeps shooting electric bolts, so don't stand next to it.
• Break all three to stun it: once the last orb falls, the boss is stunned and open to damage for a while. Then the orbs come back at full health and the cycle starts again, so save your strongest attacks for the stun.
• Second phase at half health: at 50% health it turns into the Unleashed Core Commander (a 10-second transition) and the fight continues. The orbs return in this phase too, and they circle faster as the fight goes on.

See the Core Commander page for its attacks and drops.

After you defeat the final boss

Talk to the Core after the fight for the ending and credits. The story continues afterwards (after the ending).
