The following article/section contains spoilers. Please complete Chimera Prologue before proceeding.

"Known and unknowable. This thing has haunted my life, waking and asleep, ever since I made that accursed bargain. A parasite at the core of my city. It drains my wealth, my power, my reactors... and my dignity.

This will not stand. I will see that horrendous thing destroyed.

I will be free."

Alad V

The Ropalolyst is a gigantic bird-like Sentient boss capable of flight. It can be found in the Remastered Corpus Gas City on its own Assassination node on Jupiter, requiring players to have completed Chimera Prologue to battle it. It was dispatched by the Sentients to ensure Alad V does not double-cross their "partnership", much to his displeasure.

After defeating the Ropalolyst, the player will receive WispIcon272 Wisp component blueprints and an Amalgam mod from five possible.



Despite Digital Extremes' statement that the Sentient is a Flying Eidolon, no in-game material refers to it as such, leaving its classification unknown.

Mask of the Revenant[]

A vision comes, something new is stirring within the ground. Seeking a body to call its own; longing to strike those who sent it to the grave.
A fragment of the ancient Sentient that once terrorized these plains.

Although perhaps not the same Ropalolyst, a spectral silhouette of the same Sentient breed can be seen briefly emerging from Gara Toht Lake in the Plains of Eidolon. Nakak explains that a Warframe served as a Warden to keep the sealed Eidolon at bay, until one day he foolishly tried to make contact with the Sentient. Realizing the Sentient was using him as a means to free itself, the Warden cast himself into the lake. The time spent as an "anchor" to the Sentient would infuse the Warden with its eldritch energies, transforming him into the RevenantIcon272 Revenant.

The Jovian Concord[]

After the Sentients tricked Alad V into forming an unwitting partnership, the Ropalolyst was stationed on his Gas City in Jupiter, threatening to destroy his city if he does not comply to create Amalgams for the Sentients.

During the battle with the Ropalolyst, Natah calls it her "other flesh" and tells the Tenno that its sacrifice will make way for the Amalgams to live. Meanwhile, Alad V encourages and even shows gratitude to the Tenno as they fight.


Outside of its assassination node, the Ropalolyst can occasionally be seen on outdoor tiles, causing destruction to the Gas City and leaving debris in its wake before flying off. The Ropalolyst cannot be attacked during this state.

During its assassination mission, the Ropalolyst is capable of flight. When grounded, it can walk on its blade-like "wings". It uses a variety of energy-based projectiles, and can even grab the Tenno with its claws.

  • Lasers: While hovering, the Ropalolyst can fire thin lasers from both of its claws after a short delay, dealing massive DmgTauSmall64 Tau damage, potentially enough to kill the player.
  • Nullifying Scream: When a mobility-type Ability such as the Operator's Void Dash or NezhaIcon272 Nezha's BlazingChakram130xWhite Blazing Chakram is used on the wires during Phase 1, the Ropalolyst screams, releasing a pulse that temporarily disables Transference, nullifies all Warframe abilities (except for deployed abilities such as NovaIcon272 Nova's WormHole130xWhite Wormhole) and temporarily prevents ability use for ~3 seconds.
  • Electric Stream: Upon attempting to climb any of the power lines leading to the capacitor towers, the Ropalolyst will teleport to the tower and repeatedly create a Spark Gap between two power lines that will travel towards the player. If the Tenno make contact with the electric stream, they will be staggered and will be knocked off the power line.
  • Giant Laser: When a Tenno is on the platform next to the capacitor towers, the Ropalolyst will bring the tips of its wings together and fire a massive, continuous laser that deals heavy DmgTauSmall64 Tau damage.
  • Seeking Missiles: After being grounded for the first time, the Ropalolyst fires a series of missiles with slight homing ability.
  • Grab: While grounded, the Ropalolyst can grab the Tenno with its claws, disabling all of their movement options and abilities while they are held. The Tenno will gradually lose health while in the Ropalolyst's grip until they are released. They can escape the grab temporarily by entering Operator mode. The Ropalolyst can also grab Titania in Razorwing mode.


Phase 1[]

The Ropalolyst engages the Tenno while hovering in the air. There are three capacitor towers surrounding the main platform. Approach one of the towers, taking care to avoid the Electric Stream, and wait until the Ropalolyst fires its Giant Laser, luring it to hit the tower and supercharging it.

The Tenno must also deplete the Ropalolyst's shields using DmgVoidSmall64 Void damage via Operator's Void Beam. Once its shields are depleted, the Tenno can approach the Ropalolyst using their Warframe, giving the option to board it. While boarded, the Tenno can steer the Ropalolyst and ram it into the supercharged tower, knocking it back onto the main platform and grounding it. If the Tenno takes too long to steer it, they will automatically be knocked off and the Ropalolyst will regenerate its shields.

XakuIcon272 Xaku's abilities, despite dealing DmgVoidSmall64 Void damage, have no effect on the Ropalolyst.

Phase 2[]

Grounded, the Ropalolyst will stomp around using its blade-like wings and use its Seeking Missiles and Grab and is reinforced by a small group of Amalgams. The two Ropalolyst Synovia on its back become vulnerable, destroying one of them will temporarily stun it, allowing it to be vulnerable to the Terren Charger, a massive laser that is activated by a terminal on the main platform. If the Tenno take too long to activate the laser after roughly 3 seconds, any destroyed Synovia will fully regenerate.

Phase 3[]

Once injured by the Terren Charger, the Ropalolyst will resume flight. Simply repeat the above steps two more times until it dies. On the third grounding, Battalysts and Conculysts will appear instead of Amalgams, and the Ropalolyst's entire body becomes vulnerable to damage.

Once its health hits zero for the third and final time, activating the Terren Charger will obliterate the Ropalolyst, causing the main platform to collapse. The Tenno land on part of the destroyed wreckage ready for extraction, as the Ropalolyst's corpse remains on the main platform while engulfed in flames.


  • Phase 1: Maneuver toward one of the capacitor towers, lure Giant Laser onto the tower, deplete Ropalolyst's shields with Operator Void Beam, mount Ropalolyst using Warframe, and steer Ropalolyst onto the supercharged tower.
  • Phase 2: Destroy Synovia with gunfire, activate Terren Charger terminal within 3 seconds.
  • Phase 3: Repeat above two more times until it is defeated. On the final grounding, its entire body is vulnerable.


  • Ropalolyst is pronounced Rope-a-lol-ist.
  • It was first introduced in Devstream 100, under the name Fly-dolon, and was originally intended to be an Eidolon encountered on the Plains of Eidolon.
    • It is first seen as a ghostly apparition during the Mask of the Revenant quest, emerging from the Gara Toht Lake much like other Eidolons.
    • The battle against the Ropalolyst is somewhat similar to that against an Eidolon, as players have to use their Operator's Void Beam to deplete its shield first, before they can harm its two Synovia weak points with conventional weapons.
    • The Eidolon design appears to be scrapped, as in-game never refers to it as an Eidolon. Multiple Ropalolysts also appear in The New War trailer, as well as in the She Gives, We Live Murex phase of the quest where there is a room showing a large hole with the Ropalolyst being formed from the forming pools below, and then being shot out of the Murex.
  • Despite Nakak claiming RevenantIcon272 Revenant's power would be needed to combat the spectral Ropalolyst that appears during the Mask of the Revenant, the Warframe has no bearing on the actual Ropalolyst fight.
  • Ropalo is Ancient Greek for "bludgeon". This may refer to the Ropalolyst's blunt limbs.
    • It could however also refer to Ropalidia, a genus of paper wasps, or Rhopalocera, which refer to butterflies, both alluding to the Sentient's ability to fly.
    • The name however could also be an innaccurate translation. Taking into consideration that "ropalo" means "bat" (item - club, bludgeon) in Greek, and that The Ropalolyst looks like a sentient "bat" (animal - chiroptera), one can wonder whether or not the translation from Greek was in fact accurate. If that is indeed the case, then the correct word would be "nyxterida" instead of "ropalo".
  • The Ropalolyst is also sometimes referred to by the community and the developers as "Rolypoly".
  • Along with Mutalist Alad V and Jordas Golem on Eris, and Lephantis and Zealoid Prelate on Deimos, the Ropalolyst is among the only six bosses to share a planet, while not containing a shared node (in the case of Captain Vor and Lieutenant Lech Kril). The Ropalolyst shares Jupiter with Alad V, accessible to any player who has reached his node and completed the Chimera Prologue quest.
  • The Ropalolyst is the first Sentient boss occupying its own node.
    • Ropalolyst is also the first non-Landscape boss that requires DmgVoidSmall64 Void power to defeat.
    • Its node is also the first non-quest node which Faction is solely listed as Sentient.
  • The head of the Ropalolyst bears a striking resemblance to Harrow's helmet.
  • Ropalolyst's size in-game appears to be actually quite smaller compare to its image in Devstream 100.
  • The upper body of a Ropalolyst can be seen tethered to the ceiling in a Corpus Ship Spy vault.
  • The Ropalolyst is considered friendly to the Corpus Amalgams it summoned, and will not attack them nor vice versa.


Patch History[]

Update 35.6 (2024-05-15)

  • Mobility-type abilities (i.e. Void Sling, Nezha’s Blazing Chakram, Kullervo’s Wrathful Advance, Ash’s Teleport, etc.) can now be used any many times as you like (Energy permitting) during the Ropalolyst fight, with the exception of the wire traversing portion of Phase 1.
    • Previously, the Ropalolyst would use its Nullifying Scream immediately after a mobility-type ability was used.
    • Now, the Ropalolyst will only use its Nullifying Scream after a mobility-type ability is used while attempting to bypass the wires.
      • There was a bug with Nullifying Scream that made it inconsistent and unpredictable. It would allow every 3rd or 5th cast of a mobility-type ability and then nullify completely, instead of doing so after the first cast. So we decided to fix the issue by allowing these abilities to be used freely during the fight and only trigger Nullifying Scream when cast during the wire stage. This is so that we can maintain the intended challenge and design of that Phase.
  • Fixed the cooldown for Void Sling not ticking down while playing as a Warframe nullified by Ropalolyst’s Nullifying Scream.
    • Previously, the cooldown would stop while playing as a Warframe and would only continue while playing as the Operator.
    • Now, the cooldown ticks down while in Warframe and Operator, so that you can Void Sling faster while switching between the two.

Update 35.5 (2024-03-27)

  • Fixed being trapped in the Ropalolyst Arena if a host migration occurs after the Ropalolyst has been killed.
