The Leviathan and Anahita are a duo of bosses that are usually fought after Plantera, but can be fought anytime during progression. They are summoned by killing the ??? in the Ocean.

This guide will mention items exclusive to Revengeance Mode with no special formatting and will follow the intended progression.

Terrain Preparation

The Leviathan and Anahita are intended to be fought in the ocean, where the ??? will spawn. When making an arena for this fight, several rows of platforms with large gaps spanning 15-20 tiles in between should allow for adequate vertical movement. In addition, be sure to utilize the entire length of the ocean, as room for horizontal movement is very useful due to the immense size of the Leviathan.

  • The Heavenfallen Stardisk dispatches both Anahita and the Leviathan at record speeds and is likely the strongest weapon available against both of them.

The Fight


The fight consists of two bosses, Anahita and The Leviathan, both of whom must be defeated. At the beginning of the fight, only Anahita is summoned, but when she reaches 40% health, she will become invulnerable and stop attacking until The Leviathan reaches 40%. Here, they both begin attacking the player until both are defeated. If the player leaves the Ocean biome, both bosses become invincible until the player returns.


At the start of the fight, Anahita will spawn with an ice shield that will block all non-minion piercing attacks. In order to damage her, the shield must be destroyed first, and she will also regenerate the shield at least twice more after a set interval of time passes during the fight. Anahita has 3 attacks which will converge on the player's location:

  • 8 spears which appear in a circle around the player and will continue travelling for a while after converging.
  • 3 icicles which will begin homing in after converging.
  • 6 treble clefs which converge slower and inflict the Confused debuff for 2 seconds.

These attacks will be weaker when the Leviathan is alive, and she is above 20% health. A sure-fire way to dodge these attacks is to travel diagonally as there are gaps in those areas in the attacks listed above. Anahita can also spawn Detonating Bubbles that inflict the Wet debuff. These projectiles can be destroyed by attacks, so using quickly firing attacks or piercing weapons can quickly remove these projectiles.

The Leviathan

The Leviathan will only spawn once Anahita reaches 40% health, who at this point will become invisible and stop attacking. The Leviathan tries to stay on one side of the player, only changing sides when the player crosses over. She will fire several meteors at the player which will inflict Armor Crunch and can also spawn Aquatic Aberrations that will attack the player. These summons can add up, so focus on them and try to kill them as soon as possible. When below 40% / 70% Expert Mode health, The Leviathan will perform charges between meteor barrages, but will not perform them while she is above 20% health and Anahita is still alive. These meteors have short gaps in between them so it's easier to either fall or fly upwards for the entirety of the attack.

At 40% health, Anahita will appear again. If she is killed before The Leviathan, The Leviathan will become enraged and vice versa. Once both bosses are attacking the player, focusing one boss in particular is suggested due to the sheer number of projectiles that will be spawned.

Expert Mode

Anahita is more aggressive.

Revengeance Mode

In Revengeance Mode, The Leviathan can perform her charges once she reaches 75% health instead of 50%.

Death Mode

In Death Mode, both Anahita and The Leviathan are capable of using their charge attacks throughout the fight, regardless of their health. This means that the player must be ready to either fall or travel upwards once the bosses begin telegraphing their charges (Anahita becomes horizontal and The Leviathan will roar). Anahita will also spawn her bubbles faster, so the time she spends immobile is smaller. The Leviathan will also charge again after she first charges. In addition, both bosses are enraged meaning they deal more damage and are much faster.

General Tips

  • The Rod of Discord can be used to instantly teleport out of attacks.
  • Tesla Potions can be extremely useful for this fight, as they can instantly destroy Detonating Bubbles and halt charges from Aquatic Abberations. However, note that if Anahita's Ice Shield is active and she is within the electrical aura, the Shield will repeatedly delete the aura projectile, essentially disabling it and making the player vulnerable to the Bubbles and Abberations.
