Abyssion does not spawn on its own and requires the player to kill Aquatic Hallucinations in the Aquatic Depths. They will drop Abyssal Shadows, which will inflict the False Presencedebuff once for every one picked up. Upon reaching three stacks of the debuff, Abyssion will emerge. Multiple Abyssions cannot be summoned through this process.
After Abyssion has been defeated in the world at least once, Abyssal Shadows will behave like normal Summoning items, summoning the boss on use.
While below 90% life, Abyssion will occasionally hide within its shell, greatly increasing its defense. When in its shell, it will rapidly barrage the nearest player with fast moving and heavy damaging spit projectiles.
While below 65% life, Abyssion will release large spinning whirlpools that deal massive damage to the player and knock them back, even if the hit player has an effect similar to the Cobalt Shield.
While below 55% life, Abyssion will start spawning five Abyssal Spawn every time it hides within its shell.
While below 50% life, Abyssion will release faded water ripples. These bounce along all walls, and stay within the area for 4 seconds.
Upon reaching 0 health, it transforms into its second Cracked stage. The transformation is notified with the status message, "Abyssion's shell violently cracks!"
While in this state, Abyssion will keep all of its previous attacks without the need of lost life. They will be quicker, deal more damage, and come out far more rapidly too.
Additionally, Abyssion will start releasing semi-homing slashes of dark magic, that attempt to blockade the players movements.
If the player is not in a body of water, it will enrage in a manner similar to Plantera. While enraged, it moves at a higher velocity, summons Abyssal Spawns more often, and its spit projectiles will home in on the player.
Upon defeating Abyssion for the first time, the Aquatic Depths biome's Choking Auradebuff will be replaced with the Untainted Watersbuff, allowing them to breathe water and air in the biome without taking damage. This is indicated with the message upon its defeat "The toxic haze of the depths has been lifted..."
