The Kill Box

Magnetize absorbs 25% of weapon damage (multishot counts, crits and DoT do not), ticks it as magnetic DoT, then on pop multiplies the total by roughly 2 x duration x enemies-in-bubble and releases it in a line-of-sight explosion.

Breach Surge sparks feed the bubble and the DoT makes more sparks, a positive loop worth over 10x the no-Surge damage with 20 enemies.

Fracturing Crush full-strips at 134% Strength (110% with Corrosive Projection).

Strength barely matters otherwise because the absorb does not scale with it.

1.

Cast Breach Surge (1 or 3) to blind and prime for sparks.

2.

Cast Magnetize (2) on an enemy in a corridor so the bubble also blocks fire.

3.

Cast Crush (4) to full-strip and immobilise.

4.

Shoot slightly off-centre so bullets orbit.

5.

Let the bubble expire or recast 2 near it to detonate a 42m explosion.

Near-neutral Duration (Breach Surge blind and Magnetize both ~15s base).

Efficiency covered by Equilibrium plus a Synth Deconstruct pet plus Arcane Steadfast.

Range is the priority stat, maxed; Magnetized Discharge adds a further 45% for an 11.2m bubble and 42m explosion.

Strength only needs the 134% Fracturing Crush threshold (Precision Intensify plus Growing Power, or Umbral Intensify plus Molt Augmented against Overextended).

Transient Fortitude plus Growing Power aura clear the Crush threshold.

Overextended, Stretch set the maxed Range.

Primed Flow, Equilibrium are the energy base.

Magnetized Discharge is the radius and detonation.

Fracturing Crush is the strip.

Counter Pulse is wall-piercing crowd control.

The three augments are all swappable for Streamline, Strength, Duration or Augur Reach.

Rolling Guard for the status cleanse Mag's kit lacks.

Worthy Comradery aura to make Breach Surge orange-crit.

Pick one.

Subsume over 1 or 3.

- Breach Surge is the build's engine if you keep it.

- Pull for longer-range grouping into the bubble.

- Polarize (kept, not subsumed) for shield restore and Counter Pulse.

- Ensnare to lock Acolytes and group.

Arcane Arachne for a 2.5x Breach Surge multiplier after a wall-latch, Molt Augmented for the Crush threshold.

Arcane Steadfast for free casts.

Any.

Madurai for cast speed.

Vazarin Sling as a backup.

High raw-damage projectile or punch-through weapons that orbit the bubble and store big hits: Tenet Arca Plasmor, Latron Incarnon, Miter Incarnon, Felarx, Phenmor.

Electric or gas on grouped enemies for the fastest kills (DoT does not feed the bubble, but the kills do).

The bubble blocks incoming fire, plus shield gating off Polarize or Crush, plus Counter Pulse crowd control, plus optional Rolling Guard.

It fails to status (Mag has no cleanse without Rolling Guard) and to toxin.

Equilibrium plus a Synth Deconstruct pet plus Arcane Steadfast.

Mag casts constantly, so keep the loop fed.

Line-of-sight tiles cut the explosion.

Open areas with no corridors to block fire.

Strong single-hit weapons hit the 5-million spark cap and stop scaling.

Bosses take the single-target bubble shred, which is slower.

A triple-augment build with shards.

Strong: a self-feeding nuke loop, a one-cast full strip, projectile immunity, one forma.

Weak: no status cleanse, corridor- dependent, weapon-carried, boss-slow.

Players who want a cheap nuke frame that turns a doorway into a kill box.
