Frost wins here. Snow Globe blocks every hit on the crystal without spending a thing. Gara pulls off the same trick with reflection, but she’ll cost you more forma to get there.

| Frame | Why it works | Build focus |
|---|---|---|
| Frost | Snow Globe blocks all damage on the crystal, zero fire gets through | Strength + Efficiency |
| Gara | Mass Vitrify + Splinter Storm reflect damage back at attackers | Strength + Duration |
| Titania | True flight collects remnants and glyphs across the whole tileset fast | Strength + Duration |
| Nova | Wormhole portals the squad across the Void tunnel gap instantly | Duration + Range |
| Volt | Electric Shield blocks bullets, Discharge stuns the room around the crystal | Strength + Efficiency |
| Saryn | Spores spread and scale, wiping waves before they reach the target | Range + Strength |
Best weapons for Mirror Defense
Torid IncarnonScaling gas clouds
Kuva ZarrFlattens spawn lanes
Tenet Arca PlasmorClears tight corners
Ignis WraithContinuous fire beam| Weapon | Why |
|---|---|
| Torid Incarnon | Evolved mode leaves gas clouds that scale with enemy level, the top AoE clear for endless defense. |
| Kuva Zarr | Detonations flatten entire spawn lanes; pair with Primed Sure Footed to solo an approach. |
| Tenet Arca Plasmor | Wall bouncing pellets clear odd angles, built for the tight crystal chambers on both sides. |
| Ignis Wraith | Continuous status beam keeps melee range burning without precise aim. |
Frost: park on the crystal
Snow Globe blocks every hit on the crystal. Crystals can’t be healed, so tanking is the only option that works.

His blueprint drops early and costs nothing, and you won’t need forma to build him.
Gara: the glass reflector
Mass Vitrify throws up a wall around the crystal, then Splinter Storm reflects the damage right back.

Don’t have Gara yet? Frost handles the same job for less.
Titania: fly to the remnants
True flight beats running here. Remnants and glyphs are scattered across the whole map, so covering ground fast matters more than it looks.

There’s no cheap substitute for her, though Rip Line gets you to high spots too.
Nova: portal between sites
Wormhole punches a portal straight across the Void tunnel gap between both sites.


Nova

She works fine free-to-play too, no augment required.
Volt: shield plus nuke
Electric Shield blocks bullets and buffs your damage through it. Discharge stuns the whole room.

He’s a starter frame straight from the market, the cheapest pick in this lineup.
Saryn: kill it before it arrives
Spores spread virally and scale all the way to Steel Path levels, clearing waves before they arrive.

Until your mods are maxed, Mesa clears solo for less.
