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. 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 bonus damage to Sentients and removing their damage resistances.

Due to its unique nature as the Sentient Slayer, this weapon cannot be sold once built.

    • Each rank above 30 adds a bonus damage to Sentients.

  • 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.
  • "Paracesis" may also be related to the medical term paracentesis, which is defined as "the perforation of a cavity of the body or of a cyst or similar outgrowth, especially with a hollow needle to remove fluid or gas." 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).
