Sepulcrum

Burst pistol with life-essence and lock-on modes

Released Aug 25, 2020

Sepulcrum is a mastery-rank 14 Entrati pistol with a primary-fire burst and a separate lock-on mode. Its description says primary fire siphons life essence to fuel secondary fire, while the lock-on mode lets you aim at multiple targets and release homing projectiles. Consider it when you want to alternate between direct burst fire and a deliberate multi-target attack.

Sepulcrum GUIDE

Understand Sepulcrum

Useful when…

  • Use Primary-Fire for burst projectiles with a separate Heat radial component.
  • Use Lock-On Mode to aim at multiple targets before releasing homing projectiles, as described.

Primary-fire attack

Primary-Fire is listed at 1.83 speed, with 30% critical chance, 2.2× critical multiplier, and 14% status chance. Its projectile component lists 9.6 Impact, 11.52 Slash, and 26.88 Puncture; the separate Radial Attack lists 46 Heat with falloff from 0 to 1.6 and 20% reduction. The description says primary fire siphons life essence to fuel secondary fire, but no amount or numeric charge rule is provided.

Lock-on mode

Lock-On Mode is a separate projectile entry listed at speed 1, with 38% critical chance, 3× critical multiplier, and 26% status chance. Its direct damage is listed as 19.2 Impact, 23.04 Slash, and 53.76 Puncture. Lock-On Radial Attack separately lists 480 Heat with falloff from 0 to 3 and 20% reduction. The description says to aim to lock onto multiple targets and then fire homing projectiles. The supplied stats do not specify the target cap or exact lock-on timing, so do not assume either.

Fitting and tradeoffs

The weapon is listed with a 90-round magazine and four-second reload. Its crafting data lists a 20,000 build price, 12-hour build time, one Seriglass Shard, and a blueprint, barrel, and receiver. A long reload is a practical consideration despite the large magazine. Athodai Prime is described around weak-point kills and temporary Overdrive; Cyanex has homing automatic projectiles and a magazine-emptying alt-fire; Tenet Detron is a shotgun sidearm with an alternate-fire burst. Those descriptions indicate different conditions and firing styles, not a ranking against Sepulcrum.

Limitations and tradeoffs

  • The four-second reload is lengthy, and the lock-on mode is slower than the listed primary-fire mode.
  • The siphon-to-secondary-fire description does not quantify its charging behavior; do not assume an unlisted numeric trigger or benefit.

Common mistakes to avoid

  • Do not combine the primary and lock-on attack figures; they are separate modes with different listed stats.
  • Do not assume a lock-on target cap or exact life-essence charging formula from the descriptions.
