Learn the frame.

Best for: Star Chart, first Mag, anyone who picked her as a starter

Magnetize a heavy. Shoot the bubble. Polarize when shields drop. Crush is a slam, not the kit.

Magnetize is Mag. The bubble is a damage amplifier, a grouper, and a bullet vacuum.

Your first endgame-capable version.

Best for: Steel Path Star Chart, Circuit, first Archon. Helminth is the next card.

Pull, Magnetize, empty the gun into the bubble. Polarize shards feed it. This is 2026 Mag. This is the peak you can run the day Steel Path unlocks — galvanized / arcanes, no Helminth.

The 2026 Mag identity is 'I brought a bubble and a real gun,' not Crush spam.

Best for: Steel Path Grineer, Demolysts, armor tiles, the Mag who is tired of yellow health bars

Polarize melts shields and armor. Fracturing Crush finishes the strip and freezes. Then the bubble actually kills Grineer.

Fracturing Crush is why you keep 4 on a strip Mag. Other configs Helminth it.

Gun in a Sphere

Your first endgame-capable version.

Best for: Incarnons, snipers that like a grouped target, people who picked Mag for the gun not the slam

You are a weapon platform who happens to own Magnetize. Eclipse or Roar over Crush. Hold-2 absorb is the panic button.

Not every Mag wants Fracturing Crush. This is the 'I picked the bubble to juice my Incarnon' loadout.

Key mistakes

Shooting past the bubble
The multiplier is inside. Aim at the glowing target, not the guy beside it.
Holding 2 when you meant to tap
Hold is a personal reflect. Tap is the blender. They are different buttons now.
Ignoring Polarize because 'it isn't damage'
It is your shields, your strip, and the Slash shards Magnetize wants.
Building only Strength on the starter
Duration keeps the bubble up through a magazine. Range makes Pull a room.
