ValkyrGloom Berserker

Endgame build. Gloom over Rip Line. A slow aura that also life steals. Rage plus Gloom plus claws is the ugly endurance stack.

Solo Steel Path, endurance, people who hate being rushed

Wrong drop or mechanic?

Don’t build this yet

First Rage first

This loadout sits at Endgame. It wants Forma, Helminth, or shards you may not have. Play the Starter until those systems are open — then this page is the upgrade, not the homework.

Open First Rage

Why this build?

Endgame for Solo Steel Path, endurance, people who hate being rushed

Health: Not yetHelminth, Steel Path, or Archon Hunts still closed. Play the Starter.

Play this in Steel Path
  • Rip Line is the Helminth slot on almost every 2026 endurance Valkyr.
  • Gloom is the slow that makes 855 armor look immortal because nothing swings back in time.
  • Energy is the failure mode. Equilibrium plus orbs, or you toggle Gloom off between packs.

Don’t use this for: Star Chart only · new accounts · frames played as a gun platform only · players without Helminth

Specialised investment for hard content

You don’t need the shards to run the loop. They are a later ceiling, not a gate.

Bring: Hysteria TalonsSame claw grid as Hysteria Claws. Gloom life steal stacks with claw life steal. You become a health sponge.

Medium confidence. A solid recommendation with more situational dependencies. Confidence is not verification. Verification is separate: Codex Checked against Update 43.5.

What to put on the body

Gloom (Sevagoth) over Rip Line (1)

Rip Line is movement you can replace with slides. Gloom slows the room and heals on damage dealt. Strength is the slow cap; Range is the radius.

Helminth is locked. Tick it on Progress before you subsume.

Tonight

What is actually up

30 minutes, one hour, or two — matched to this loadout, not a dump of the Origin System.

  1. 30 minutes

    Farm Brief Respite

    One named gap. The Index / Nightwave

  2. 60 minutes

    Brief Respite, then Forma

    Finish the missing named card, then spend a Forma if a polarity is still fighting you.

  3. 120 minutes

    Subsume Gloom (Sevagoth)

    If you are logging off after this, stop at the named component. Do not start a second Forma session tired.

Keep this up

Gloom loop

Pocket card. Stick this on a second screen; the long version is the mission below.

  1. 1Gloom (1). The room wades.
  2. 2Warcry (2).
  3. 3Hysteria (4) and walk through them. Life steal from claws and Gloom at the same time.
  4. 4Rage still saves you if something gets through. Recast Gloom if the drain dropped it.

First mission — press these buttons

  1. 1

    Gloom the tile

    1

    1. The room slows. Drain starts. You need kills or orbs.

  2. 2

    Claws in the soup

    4

    2 then 4. Walk through them. Health should not move down.

Common mistakes

  • Leaving Rip Line and wondering why you cannot Gloom

    Helminth 1. Slide is your hook now.

When this feels easy

  1. 1If energy dies, toggle Gloom off between packsIt is a drain, not a toggle-and-forget on a 100 energy pool.
