Corallus (also known as the Coral Monster) is a L'Borean boss in Advent of Ascension. She is summoned by throwing an Amphibiyte Lung in water.


Corallus will pursue any player nearby; if the player is hit on land they are inflicted with Slowness IV for 2.5 seconds and a strong Weakness debuff for 5 seconds. If the player is hit while in the water they are instead knocked downwards below the surface of the water.

Every 16 seconds, Corallus will leap upwards into the air, letting out a roar, and if she lands in water then she will fall below the surface of the water before re-emerging. During this time she will summon 3-4 Homing Projectiles which will pursue the player and explode either upon reaching the player or when they are hit.

Every 10 seconds, Corallus will also sometimes change colour into a darker shade of blue, inflicting herself with Strength IV for 4 seconds.
