Guardian — Stonewall Frontline — Guardian Build

TL;DR

Guardian is the tank / defense class built around the Stonewall Repulsor.
The documented seed loadout uses GK2 or Stubby with a magazine roll plus Devastator Blaster.
The core loop is: set barrier in a chokepoint, hold the line, repulse breakers.
Falconer is a documented synergy because Guardian can hold ground while the drone roams.

Synergies and playstyle tips

Build around chokepoints whenever the arena allows it.
Put the barrier where teammates can fight behind it instead of scattering across the room.
Use repulse to stop enemies that break through the frontline.
Falconer is the documented synergy: Guardian anchors the team while the Buzzard drone roams.

When to choose Guardian

Choose Guardian when your group needs a stable point to fight around. Rogue Core's run structure pushes teams to make decisions under pressure: mine now or move, start an event or skip it, take a harder route or preserve the run. Guardian makes those decisions easier by creating a temporary safe shape in an otherwise chaotic room.

This build is strongest when the team agrees to use the barrier. A Guardian who places Stonewall well but watches teammates scatter has not solved the fight. Call the hold point, place the barrier where weapons can shoot through the lane, and use repulse as the emergency tool when enemies cross the line.

GK2 or Stubby gives the build a practical primary weapon plan, while Devastator Blaster covers close-range panic and splash situations. The weapon choices matter because Guardian should not become passive. The role is defensive, but the team still needs kills to end the wave.

Common mistakes

The biggest mistake is overvaluing a bad chokepoint. If the room is too open or enemies can reach the team from multiple angles, a barrier becomes a reset tool rather than a permanent fortress. Drop it to buy space, then rotate.

Another mistake is saving repulse for a perfect moment. If a dangerous enemy breaks the team's formation, use the tool early enough that the squad can recover. Guardian's value is not only preventing damage; it is preserving the team's ability to make clean decisions.

Counters and struggles

Open-arena swarms where chokepoints do not form are the documented counter.
If the room gives no natural hold point, stay mobile and use the barrier as a temporary reset rather than a permanent wall.
