Why this build?
Starter for Star Chart, first Mag, anyone who picked her as a starter
Health: Inventory unknown — Mark what you own. Until then this is a recommendation, not a test you failed.
- Magnetize is Mag. The bubble is a damage amplifier, a grouper, and a bullet vacuum.
- Polarize restores your shields and strips theirs. You are a shield caster, not a health tank.
- Crush waits for Fracturing Crush if you want armor strip. Starter just slams.
Don’t use this for: Eidolon hunting · Steel Path endurance · level-cap content
0 Forma, basic mods, no Helminth or shards required
You don’t need the shards to run the loop. They are a later ceiling, not a gate.
Bring: Any hitscan / pellet gun — Magnetize sucks bullets into the bubble and multiplies them. A shotgun, a Soma, a Kuva Nukor — if it fires projectiles or hitscan, the bubble eats them.

Pocket card. Stick this on a second screen; the long version is the mission below.
- 1Pull (1) a pack into a pile.
- 2Magnetize (2) the heaviest target in the pile. Shoot the bubble. Everything inside shreds.
- 3Polarize (3) when your shields dip, or when Corpus shields need peeling. Shards orbit you and slash.
- 4Crush (4) is a slam for leftovers. Do not build the starter around it.
