An ancient weapon designed by the Entrati. Primary fire siphons life essence from the target to fuel a devastating alt fire. This large, weighty double-barreled pistol delivers twin projectiles that pack a punch, exploding on impact. Alt fire puts the weapon in lock-on mode. Aim to lock onto multiple targets, then fire to unleash homing missiles.

The Sepulcrum is an Orokin Era weapon created by the Entrati, a burst-fire explosive sidearm that builds charges on kills to allow use of the Alternate Fire, a lock-on missile barrage.


Sepulcrum is acquired by reaching the Rank of Acquaintance with the Entrati. Father sells the main blueprint for ReputationLargeBlack4,000 and component blueprints for ReputationLargeBlack2,000; a total of ReputationLargeBlack8,000 is needed for all parts. The main blueprint is also offered as a rank-up reward.

Additionally requires the rank of Neutral with Solaris United and Offworlder with the Ostrons in order to acquire Travocyte Alloy and Coprite Alloy respectively required in its construction.

    • Requires locked-on targets to fire.
    • Extremely low fire rate.

  • One main blueprint is required to reach the Rank of Clearance: Modus with the Necraloid.
  • Despite ostensibly being unlocked at Acquaintance with Entrati, the weapon's components require a Trapezium Xenorhast for which the blueprint can only be obtained at Associate or higher.
  • When the charge gauge is full, Alternate Fire can toggle between its burst-fire and lock-on modes.
    • Up to a maximum of 5 targets can be locked-on by aiming at enemies within 80 meters, indicated by the circular reticule.
    • Locked-on targets are marked by a white diamond.
    • If the target moves 100 meters away or dies while being aimed at, their lock-ons are removed.


  • A sepulcrum is a grave or similar burial place, such as a tomb.
  • The design of sepulcrums magazine is highly reminiscent of a type known as a "casket magazine".

Patch HistoryEdit

Update 29.1

  • Decreased the unguided flight time of the Alt Fire on launch from 0.06s to 0.03secs.
  • Decreased the unguided flight time of the Alt Fire smoothing from 1s to 0.4secs.
    • This makes the Alt Fire projectile start to home in on their targets faster and curve more acutely towards them.
  • Decreased Alt Fire re-arming delay from 0.2s to 0.01secs.
  • This decreases the time between being able to lock onto additional targets after the first.
  • Increased max lock distance from 60m to 80m.
  • Increased loose lock distance from 80m to 100m.
    • This increases the distance you can lock onto targets with Alt Fire from 60m to 80m, and lock won't be lost unless the targets move beyond 100m.
  • Fixed cases of the Sepulcrum Alt Fire not properly targeting enemies.

Hotfix 29.0.6

  • Fixed the Sepulcrums Alt Fire homing projectiles sometimes endlessly circling low profile targets like the Deimos Carnis enemy.
  • Fixed Sepulcrum local firing sounds playing for Clients.

Update 29.0

  • Introduced.
