Morpha the Aquatic Mass Boss Fight Guide – Core Keeper
Where to Find Morpha the Aquatic Mass?
Once you’ve unlocked the newest biome, you will need to have a brand new item called “Morpha the Aquatic Mass Scanner”.

To craft this item, you will need:
- 10 Ancient Gemstone
- 10 Mechanical Parts
- 90 Slippery Slime
To locate the boss, you will need to look for a larger island filled with blue slime. The blue slime will have dark-blue dots on the map.

Boss Fight
When the arena has been found, you will need to place down the summoning idol in the center where there is a carving in the ground.

When he spawns, the first thing that you want to do is back off and start hitting him with a ranged weapon, as he will start spawning a bunch of bubbles that will float in random directions.

His next move will turn him white, indicating you that the boss will jump to your location. Move away to dodge this attack.

When the boss reaches 20% health, he will enter an enraged phase. Use all your damaging abilities and weapons to defeat him as fast as possible, as he is the strongest then.
