Morpha the Aquatic Mass is a boss enemy. It is an optional side boss that is not required to be defeated to advance the story.


Morpha spawns in The Sunken Sea. It spawns approximately 1400 tiles away from the core at a random angle, or 2.97 times longer radius than the great wall. When you get close, your screen will shake periodically. Its lair is a big open space covered with ground slippery slimes. These ground slimes turn your movement slippery, making your character harder to control.

To respawn Morpha after it has been killed, place Giant Slime Summoning Idol on its rune circle. The idol can be purchased from the Caveling Merchant for 500Ancient Coin. The merchant will restock their items after some time has passed.


Morpha attacks by jumping on top of the player. Just before jumping it will flash white, giving you ample time to react. It can also shoot bubbles in random directions. These bubbles travel to a certain distance before stopping, and will disappear after a while. At 30% health it will enrage, increasing its speed and frequency of attacks.

You should be familiar to its jump attack, as it's shared by all slime bosses, mitigate it by shielding or dashing away. With enough defensive boost, you can melee and tank all of its attack by shielding. Otherwise, you can attack with a range weapon while running around, avoiding the bubbles as best as you can.
