Siren and Leviathan
Siren and Leviathan
- If you were looking for something other than the Siren or the Leviathan, see Siren (disambiguation).
The Siren and The Leviathan are a duo of bosses that can be fought at any point in the game, but will only drop most loot after Calamitas or Plantera have been killed. It is recommended that the player acquire post-Plantera equipment before engaging the bosses, as they are very challenging and require the management of two boss-tier enemies with several summons all at once.
Spawn[edit | edit source]
To begin the boss fight, the player has to kill the ??? in the Ocean. Doing this will spawn just The Siren at first, and The Leviathan herself will only spawn once The Siren reaches half health. In Death Mode, they will both spawn simultaneously when the ??? is killed.
Bosses[edit | edit source]
Behavior[edit | edit source]
This boss encounter is made up of two individual bosses: The Leviathan and The Siren. Both enemies must be defeated to count as a full kill and receive loot. Only The Siren is summoned at the start, but after she reaches 50% health, The Leviathan is summoned. They become invulnerable to damage if the player leaves the Ocean biome during the battle.
The Siren[edit | edit source]
- She rapidly fires damaging bubbles, water spears, ice mist and treble clefs at the player. These attacks all do identical damage.
- She periodically generates an ice shield, rendering her invulnerable to damage until it's destroyed.
- At 50% health, she begins spawning stationary blue Siren Clones that launch projectiles at the player.
- In addition to this, she begins to chase and ram into the player with her spear.
- She becomes enraged if The Leviathan is defeated first.
The Leviathan[edit | edit source]
- She mainly stays on one side of the player. Switching sides if the player went to another.
- She fires large orbs of energy.
- She summons Aquatic Aberrations and Paraseas to attack the player.
- She becomes enraged if The Siren is defeated first.
In Expert Mode[edit | edit source]
- The Siren is much more aggressive.
- The Frostburn debuff inflicted by the ice mist and Confused debuff inflicted by the treble clefs last double the time
In Revengeance Mode[edit | edit source]
- The Siren's ice shield blocks piercing projectiles.
- The Leviathan shoots faster.
In Death Mode[edit | edit source]
- Both bosses are summoned simultaneously at the beginning of the fight.
- Both bosses are always in their enraged state.
Summons[edit | edit source]
|Siren Clone||Below 50% health|
Tips[edit | edit source]
- Any accessories which increase speed and damage in water may be useful, as they will make dodging the Leviathan easier.
- Melee players should focus on the Siren, as she will very aggressively lunge at the player when below 50% health, potentially dealing lethal damage very quickly. The Leviathan's attacks are not terribly difficult to dodge even when she is enraged, though care should be taken not to go too close to her mouth.
- Do not leave the Ocean, otherwise both the Leviathan and the Siren will be immune to attacks.
- Minions don't seem to be able to target the Leviathan and will kill the Siren instead, so Summoners might want to switch gear for this encounter.
- Alternatively, one can use the
- Try to focus on dodging attacks more than on targeting.
- Making a lot of platforms that are the whole length of the Ocean may make it easier to dodge her attacks.
Notes[edit | edit source]
| Alternate Siren|
- Even though the summon appears even at the very beginning of the game, it's not recommended to fight this boss until you get Hardmode gear.
- Some projectile on-hit effects, such as the SHPC's primary fire, do not activate when hitting the Siren's frost shield.
- In the possible, though unlikely, circumstance that you manage to lure the Leviathan and the Siren to the Sulphurous Sea biome, it will be considered as the Ocean and they will be vulnerable.
- Although it may be hard to notice, the Siren has two possible sprites. The only difference is on its chest and hands, where they may be either blue or green.
- This is the reason why there are two variations of the Siren's Heart.
Trivia[edit | edit source]
- The Siren's theme is Siren's War Cry, which is by the artist DM DOKURO.
- Siren's War Cry is the only Calamity theme to not be featured in its own video, instead only appearing in an "Extended" version alongside the other themes for the Siren and Leviathan. This is due to the fact that Siren's War Cry was made some time after the other two themes, in response to a rework to the fight which now included the Siren being fought on her own.
- When The Leviathan appears, the theme changes to Forbidden Lullaby, also by DM DOKURO.
- Unlike other bosses with multiple characters, like The Twins and Calamitas, The Siren and The Leviathan share the same trophy.
Lore & Origin[edit | edit source]
The Leviathan was once far smaller compared to the massive beast she is now. A fairly large, armored anglerfish that was extremely territorial, often shredding those foolish enough to enter her section of the dark abyss in her steely jaws or by sending her entourage of males to do the work for her. However, after years of devouring most of the local wildlife she became bloated and old, no longer able to move herself at a decent speed. It was around this time that a lonely sea creature, one of the last ones remaining there, swam slowly up to the giant creature in curiosity. The creatures' blissful ignorance nearly cost it its' life as the leviathan burst forward and attempted to devour it. The creature avoided the attack easily and swiftly. The leviathan, tired and worn out from just one attempt, did not continue her attack.
As time went on the creature kept appearing at increasing frequency, observing and avoiding the leviathan's jaws with ease. Eventually the leviathan gave up entirely, leaving the creature to observe her as she slowly withered away from lack of food. One day she could no longer swim and fell down to the sea floor. It seemed like the end for this massive beast...until she saw that same creature that seemingly taunted her with its swiftness swimming in front of her with several dead fisherman and sea creatures collected in a large trawl net. The creature smiled and fed the leviathan repeatedly over the course of several days. Soon she was able to swim once again. However, the leviathan was still far too large to get anywhere quickly, and the creature had shown her that the only food sources left were up near the surface. The feminine creature assisting her could only bring so much nourishment by itself.
In an act of desperation she resorted to forsaking her back half by ramming her side against an underwater cliff; the cliff side cracked and fell, tearing her in half. She survived this and left her home in the abyss, following the creature leading her to seek out prey located in shallower waters. She then adapted to capturing the local divers in her jaws by disguising herself as a massive underwater rock formation. The divers would soon become leery of the once-calm waters near the beaches. This did not stop the feminine creature from assisting the leviathan by infatuating fisherman and then drowning them once they ventured too close. The fisherman then created tales and myths of a deceptive yet beautiful creature aptly named "The Siren". Tales of the duo continued to circulate but never held much merit and were often dismissed. Now the Leviathan waits patiently for the next diver to approach with the Siren close to her side, ready to help her newfound friend.
