The Siren and The Leviathan are a duo of bosses that can be fought at any point in the game, but is intended to be fought during Hardmode. 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 Siren and The Leviathan. 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 water spears, ice mist and treble clefs at the player. These attacks all do identical damage.
- Ice mist homes in on the player and inflicts the Frostburn debuff for 4 seconds, the Chilled debuff for 2 seconds, and the Frozen debuff for 0.5 seconds.
- Treble clefs linger for an extended period of time and inflict the Confused debuff for 2 seconds.
- Water spears inflict the Wet debuff for 4 seconds.
- She additionally can summon Detonating Bubbles that inflict the Wet debuff for 7 seconds.
- She periodically generates an ice shield, rendering her invulnerable to damage until it's destroyed.
- The ice shield blocks non-minion piercing projectiles.
- 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 meteors.
- She summons Aquatic Aberrations and Paraseas to attack the player.
- Aquatic Aberrations attempt to fly above the player before charging.
- Paraseas attempt to face the player while accelerating toward them.
- She becomes enraged if The Siren is defeated first.
- When below 50% health, she will begin to charge at the player.
In Expert Mode[edit | edit source]
- The Siren is much more aggressive.
In Revengeance Mode[edit | edit source]
- The Leviathan shoots faster.
- Detonating Bubbles inflict the Marked debuff for 6 seconds.
- Aquatic Aberrations inflict Marked.
- At 50% and again at 25% health, she will spawn a stationary blue Siren Clone that launches water spears at the player.
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.
- The Siren summons a Siren Clone at the beginning of the fight instead of at 50% health.
- Siren Clones shoot faster.
Summons[edit | edit source]
Aftermath[edit | edit source]
Notes[edit | edit source]
- 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.
- The Siren's frost shield deletes projectiles on contact. This means some projectiles will fail to function correctly, such as the SHPC's primary fire.
- 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.
- Both the Siren and the Leviathan will each drop 5-15 Greater Healing Potions separately when killed.
- When you have the Wet debuff, the Siren's projectiles have a lower velocity.
Tips[edit | edit source]
- Making 3-4 layers of platforms that are the whole length of the Ocean may make it easier to dodge their attacks.
- The Terra Blade or the Terra Edge are both extremely powerful against the Siren and Leviathan, as both have high fire rates and damage values.
- The Conclave Crossfire, when paired with any homing bullets, is very effective for both bosses.
- Magic staffs such as the Meteor Staff and the Terra Ray are very effecting at hitting the Leviathan due to its large hitbox. However, the damage these deal alone is not substantial and should be complemented with other single target items.
- The Blizzard Staff can effectively defeat The Leviathan due to her large hitbox.
- 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 Interact key (right click) while holding a summoner weapon to target the Leviathan instead.
- The Duststorm in a Bottle is a good choice for Rogue players due to its high base damage.
- The Lunic Eye and the Everglade Spray are extremely useful in reducing the Leviathan’s high defense.
- Ankh Shield provides immunity to knockback and the confused debuff, making it an effective accessory during the fight.
- Dodging is key during this fight, thus dashing accessories such as the Counter Scarf and the Master Ninja Gear should be prioritized.
- It is recommended to use Angel Treads or a Water Walking Potion to stay afloat during this fight, allowing you to reset the players wings on contact.
- Once the Leviathan has reached 50% of her health, care should be taken to be aware of where she is as she will start charging the player. Should she be on the left or right side of the player, it is important to dodge it either moving down or above where the Leviathan is going. The Rod of Discord or Slimy Saddle mount can be quite handy for this case.
- The Zerg buff can reduce the average waiting time for the ??? to spawn by 30x, making the bosses much more readily available.
- This will also spawn ocean enemies at a 30x rate so be cautious.
Trivia[edit | edit source]
- The Siren's theme is Siren's War Cry, which was composed 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 sometime 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, which was also composed by DM DOKURO.
- If the Calamity Music add-on mod is disabled, Boss 3 will play instead for the Siren and Leviathan.
- Unlike other bosses with multiple characters, like The Twins and Calamitas, The Siren and The Leviathan share the same trophy.
- In previous versions of the mod, the Siren had two color schemes with one randomly being chosen upon her spawning. Some of her features would be either greener or more blue. This was the reasoning for Siren's Heart having two variants based on color.
- Originally, the Siren and Leviathan shared their lore entry.
Lore[edit | edit source]
The Leviathan[edit | edit source]
The beast we call the Leviathan has not always been the behemoth we know it as now. Once an armored angler of unknown origins, she spent much of her juvenile life in the depths of the oceans, preying upon any unfortunate enough to stray into her territory. It was clear, however, that she was no simple fish. Constantly surrounded by an entourage of waiting males, the Leviathan was likely an alpha female, and perhaps the very last of her kind. Any attempts by researchers to delve deeper into her habits however, had proven risky and were thus hardly undertaken, as there was little to be gained from such an expedition. And so, she lived a wanton life, devouring to her heart’s content, finding little to oppose her. However, there would come a day when eventually, a creature would escape her steely jaws. Like a lantern in a deep night, a distant light flitted through the darkness. However foolish it was to draw attention to oneself in that ebony pit, it seemed that the creature was ignorant of dangers, or foolishly confident. Lying in patient wait, the Leviathan hungrily eyed the dancing light. And her chance soon came. With a roar and a surge of water, which likely raised turbulence even on the surface above, she charged with her jaws agape to swallow the creature whole, and yet… In the settling debris thrown up from her attack, the light flickered in the darkness, clearly shocked, but only for a second, as it soon departed, having learned of the dangers of the deep. The Leviathan herself lay stunned, for none had escaped so frivolously from her maw before.
However, decades passed, and this singular incident soon faded from the Leviathan’s memory. She continued to feast and grow, becoming larger and larger, until at one point, it became clear that her bulk would no longer allow to hunt as efficiently as she had done before. In a cruel twist, the once terror of the deep became immobile, and began to starve, no longer having the ability to sustain her massive physical form. She came to a rest upon the muddy seabed, hardly able to rise from her position. Had anyone come across her at that point, they might’ve mistaken her gargantuan form resting upon the sea bed as a geological structure, so encrusted in barnacles and other ocean flotsam from age was she. And as the Leviathan began to close its eyes perhaps for the final time, in its dimming vision, it saw a dancing light. The light flitted through the obsidian waters, like a lantern in a deep night. And the memory from all those years resurfaced. Angry and desperate, the Leviathan somehow found the energy to pull its massive form from the seabed, straining, roaring weakly, to- in its final moments- vanquish the one creature which might have reason or cause to look down on the proud, yet crippled predator. And crippled she was. Unable to keep going, she collapsed once more to the sea bed in a massive cloud of silt. In these moments, the light came closer, wary, yet still innocently curious. The Leviathan’s massive eye shifted while it lay on the bottom, watching the light. It turned out to be a vaguely female humanoid, though not different from a typical fish in its lower body. It gave a start at noticing that it was watched, and waved a hand in greeting. Of course, this meant nothing to the Leviathan, who rolled her eye back, and closed her eyelids. She would now rather be left to die in peace. Yet after a period of time, unmeasured from the Leviathan’s perspective as she had long since lost track of such trivial things, she felt something brushing her scarred snout. Once again opening her eyes, she saw the creature which had visited her before. From her arms, a massive trawler’s net trailed behind her, filled with fish and attached to drowned fishermen, who had likely once called that net their own. The creature smiled upon seeing that the Leviathan had noticed her. She swam into the Leviathan’s slack jaws, fearless of her situation, and began to empty the net. However, even as the Leviathan gradually regained her former strength, she lay still, allowing the creature to roam unimpeded around her. It was now clear that this creature had shown nothing but good intent to her. It had an interest in the Leviathan. So when the creature began to beckon for the Leviathan to move once more, to follow her to the surface, it took only a moment of hesitation for the Leviathan to ascend, going slowly to acclimatize to the change in pressure.
Nearer to the surface, though no beasts of the size she used to devour lived there, she found an abundance of food. The Siren, for that was what the creature was, lured unsuspecting sailors to the Leviathan’s position, acting as a lure in exchange of the company and safety of the massive beast. The Siren's voice was both melodious and alluring, and her ability to cloud the skies and obstruct vision created a fantastical illusion in which entire fleets of boats would disappear, never to be seen again. Under the Siren's care and companionship, the Leviathan eventually regained her strength. The ancient beast would spawn legends aplenty, of unknown noises in the mists, and colossal shapes moving on the horizon. However, for the most part, the Leviathan lay dormant in shallow waters, resting, in order to conserve her strength. This was her lifestyle now, and while it may not have suited the former terror of the deep, it did not mean she was a pacified beast. If any were to disturb its slumber, or fall for the Siren’s illusions, she would awaken with her former grandeur, to devour the one who had strayed too far from the shore.
The Siren[edit | edit source]
The mysterious creature that had found and aided the old Leviathan had a long and troubled story of her own.
She was born into floating city built by a civilization that worshipped a living siren goddess. Only the high caste sirens hand-picked by the goddess were allowed to reproduce, and their children were given to the other sirens to foster. One particularly weak newborn was handed over to a troublesome siren who lived on the fringes of the city. The city's cruel laws often led to long periods of exile as punishment for insubordination or other troubles, and the elites believed raising a child could help reform this siren's spirit.
The outcast siren accepted the feeble child and gave her the name Nahlyn. Growing up outside of the city's norms, Nahlyn experienced a very unusual childhood compared to a typical siren. After learning of the twisted law of her species and the experiences her own parent, Nahlyn grew to despise the group, beginning to consider it a "cult". The elite of the city determined that Nahlyn's upbringing and her attitude were unacceptable; Nahlyn was only fourteen when she returned home to find two zealots standing over the crumpled corpse of her mother. They bound her and brought her back to the city for cult indoctrination, gagging her when she screamed and rebelled. Nahlyn spent the next several years serving the siren cult, feigning obedience and climbing the ranks in the hopes that one day she could escape her waking nightmare. She would prepare for years, to grasp her chance.
That chance would soon come, disguised as a catastrophe. The city was prone to the whims of the ocean currents, and one day, drifted near the mouth of a massive abyss. Knowing full well the dangers of the deep, the worshippers immediately took action, closing off many of their open streets, and propelling their home further from the mouth of the cave. However, it was too late. Rising from the darkness, a massive beast- a true leviathan- roared in displeasure. It would take all they had to even escape alive from its jaws. Nahlyn would take advantage of this. Earlier that day, she had been entrusted with guard duty in the inner temple by the elites who had assumed her indoctrination was successful. It had been her chance to steal a powerful weapon and make an escape. This was made only easier by the Leviathan’s rage. As massive tremors rumbled through the halls, most of the surrounding guards barked orders in confusion, and many left to help defend the walls. In seconds, she had been left alone in her area to guard the inner sanctum. Only those who were in possession of the two key parts to the sacred weapon were left behind, panicked, and hopelessly frightened. Nahlyn, however, had nothing to lose compared to those who had lived decadent and opulent lifestyles within the temple complex. In a flash, she had slammed her spear into the back of one’s helmet, knocking them unconscious, and, turning the corner, buried it into the gut of other, pinning them to the stone. Still gritting her teeth in determination, she tore the key pieces from their necks, even as the rubble tumbled from the ceiling above, hurriedly assembled them, opening the door to the mythical trident, Atlantis.
Without hesitation, she grasped the weapon in her hands, snapping it from its pedestal. A surge of power flowed through her, as she felt the Siren’s powerful affinity with water coursing through her body. She heard shouts from outside. Another guard, probably having also abandoned their post, rushed inside. Without hesitation, she spun the trident so its prongs pointed towards the unfortunate guard. The pressure surrounding her dropped with a lurch, and the sound of shrieking metal mixed with screams filled the air, as the guard’s armor collapsed in on itself. Turning her back on the bloody scene, she willed the water within the chamber to burst the temple walls like an eggshell. Finally, she was free. Amidst the chaos of the city, as the Leviathan tore through its walls, and the sudden realization that they had been betrayed, Nahlyn shot upwards, aiming to reach the sun of the world above, and the freedom it represented to her. Later on, she would have time to stop, and remembering the creature who had allowed her escape, she vowed that if ever the Leviathan would need aid, she would assist it in any way she could.
