Mag — Shrapnel Engine
Endgame build. Pull, Magnetize, empty the gun into the bubble. Polarize shards feed it. This is 2026 Mag.

Wrong drop or mechanic?
Don’t build this yet
First Bubble 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 BubbleWhy this build?
Endgame for endgame / endurance Exterminate, packed tiles, anyone who wants Mag to delete a clump
Health: Not yet — Helminth, Steel Path, or Archon Hunts still closed. Play the Starter.
- The 2026 Mag identity is 'I brought a bubble and a real gun,' not Crush spam.
- Shards from Polarize orbit you, then get sucked into Magnetize. That loop is free Slash.
- Hold-2 absorb is a panic reflect. Do not confuse it with the tap bubble.
Don’t use this for: Star Chart only · open-world / Eidolons · new accounts
Specialised investment for hard content
You don’t need the shards to run the loop. They are a later ceiling, not a gate.
Bring: AoE / multishot primary — Torid Incarnon, Kuva Nukor, a shotgun with galvanized multishot. The bubble multiplies projectiles. Beams are comfort. Bows are slow.
Alternative if…
- You don’t have Helminth yet → First Bubble
- Star Chart only → First Bubble
- New account or low investment → First Bubble
- This is too much Forma / cost → Shrapnel Engine — Optimised

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
Breach Surge (Wisp) or Nourish (Grendel) over Pull (1) — keep Crush if you want the strip nuke; or Crush (4) if you only want the bubble
Overframe 43.0 Magnetize nuke keeps Crush for full strip. Pull is the grouping you can replace with Surge blinds. Nourish over Crush is the energy version — pick one, do not sell Magnetize.
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.
30 minutes
Farm Growing Power
One named gap. The Silver Grove quest
60 minutes
Growing Power, then Forma
Finish the missing named card, then spend a Forma if a polarity is still fighting you.
120 minutes
Subsume Breach Surge (Wisp) or Nourish (Grendel)
If you are logging off after this, stop at the named component. Do not start a second Forma session tired.
- Farm Growing Power
The Silver Grove quest

- 1Nourish or Roar (4) once per tile.
- 2Pull (1) the pack. Magnetize (2) the densest body. Empty the gun into the sphere.

- 4If the bubble is leftover junk, recast 2 or detonate with Magnetized Discharge.
First mission — press these buttons

Buff, yank, bubble
