The Sentient slayer. An offering from Ballas.
Take this... the idea of it... it is the only way your war can end.

The Paracesis is Ballas' signature weapon, introduced in Update 23.10 (2018-10-12). Also known as "The Sentient Slayer", the weapon can gain additional max ranks after polarization capping at rank 40, with the additional ranks applying a damage bonus to Sentients and removing their damage resistances.

The Paracesis cannot be sold, but crafting it is not required for story purposes.

  • Vazarin Pol stance polarity matches Mod TT 20px Cleaving Whirlwind and Mod TT 20px Tempo Royale.
  • Polarizing the weapon increases its max rank by 2, capping at rank 40 after 5 polarizations.
    • Each rank above 30 adds a bonus damage to Sentients and increases mod capacity. At rank 40, the weapon gains DmgVoidSmall64 Void damage properties against Sentients.

  • Uniquely, If no stance is equipped on the Paracesis, then it will use Mod TT 20px Tempo Royale's entire moveset instead of the normal stanceless moveset for Heavy blades.
  • The weapon's max rank caps at 40 after 5 polarizations (max rank increases by 2 per Forma added).
    • Additional polarizations can be added when the weapon reaches its new max rank at that polarization level.
    • Each additional rank also gives Mastery Rank Experience, giving 4,000 points in total.
    • Mod capacity scales with the additional ranks, and can reach a total of 90 at rank 40 with an Orokin Catalyst installed and a matching stance mod.
      • Without an Orokin Catalyst, the max is 50. Combined with the five polarized mod slots required to reach that point, an Orokin Catalyst might not be required to finish modding the Paracesis.
      • After polarizing a weapon, any additional mod capacity above 30 (60 with an Orokin Catalyst) will not take effect until the weapon's rank reaches 31 and above.
    • Paracesis' stealth damage bonus does not increase past the usual maximum of 7, reached at rank 30.
    • Each rank above 30 adds a bonus damage to Sentients.
    • At rank 40, all attacks reset Sentient and Shadow Stalker resistances, and changes the Profit-Taker Orb's shield weakness.

Lore & History[]

“You're not supposed to be in here! You're going to ruin the surprise!”
The following article/section contains spoilers. Please complete the Chimera Prologue and The New War quests before proceeding.

The Operator follows The Man in the Wall and encounters Ballas, whose Orokin body has become Amalgamized with Sentient. Cursing Natah, he constructs the idea of the Paracesis in front of them and instructs them to take it in preparation for The New War against the Sentients. The encounter is revealed to be a vision, arming the Operator with knowledge of the weapon.

However, delivering the Paracesis to the Tenno turned out to be a ruse. After arriving with the Paracesis, Ballas reveals to have been in control of the Sentients all along; he steals the weapon and then stabs the Lotus and the Operator with it before banishing them into a Void portal.

After the Lotus and the Operator returns to confront Ballas for the final battle, with Ordis reconstructing the Paracesis, Ballas eventually manages to get the upper hand in the fight, stealing the Paracesis and stabs the Lotus again. He attempts to attack again before the Tenno jump and disarm him with a Narmer Veil, finally ending Ballas' threat for good.


  • Paracesis is the first weapon:
  • Paracesis appears to be a corruption of Paracelsus, the famed 16th-century Swiss alchemist. Some portraits of Paracelsus depict him holding a sword by the pommel which, depending on the source, was said to contain either the mythical Philosopher's Stone or the Azoth, a rumored substance that could cure any illness or dissolve any material.
    • Additionally, Paracelsus was the first person to describe the creation of a Homunculus, a small, fully formed human being, via artificial means. This could allude to Ballas' creation of the Warframes and, albeit indirectly, the Sentients.
    • Paracesis may also be a corruption of Paracentesis, a medical procedure where the abdomen is punctured with a hollow needle in order to sample or drain bodily fluids. If this is the case, then it would metaphorically allude to the function of the sword as a curative instrument against a "cyst" or "infection" (the Sentients).
    • Paracelsus is known as the father of toxicology, with one of his most famous tenets being that the dose makes the poison, referring to how otherwise harmless chemicals may become deadly in certain doses. Combined with Ballas's rant referring to the Lotus as a venomous viper, it may be a statement on the Lotus changing from a benevolent force to malevolent now that she's taken a more personal role.
  • The prefix para has a variety of meanings, including 'abnormal', 'resembling', or even from organic chemistry where it means having two substituents in opposition to each other. The suffix esis means action or process. One interpretation of the name would be the process of becoming abnormal. Another that it is the process of becoming a substituent opposed to another substituent. Either really works well for the background surrounding Ballas and the Operator getting the sword.
  • In Devstream 123, [DE]Steve advised not to sell the Paracesis (despite not being possible to). On Update 27.0 (2019-12-13), the weapon would come into play in triggering the Erra quest, however the quest's activation was changed in Update 27.2 (2020-03-05) to no longer use the Paracesis.
    • The Paracesis is not required to start The New War, despite initially appearing on the Warframe's back even if the player doesn't own one or did not equip it prior to starting the quest. An unranked, unmoddable Paracesis is also temporarily given to the player toward the climax of the quest.
  • A Paracesis Sheath can be obtained as an Orbiter Decoration after completion of Chimera Prologue, purchased from Cephalon Simaris for ReputationLarge 50,000. The sheath itself is not present when the Paracesis is holstered due to it being a heavy sword instead of a Nikana.
