Phantasma

Irradiate enemies with a continuous stream of deadly plasma. Built as a shotgun / close-range clear option for squad clear and mission pressure.

Signature

Phantasma is not a signature weapon — any frame can use it without a signature passive.

When to Pick

• You want a Shotgun that fits a shotgun / close-range clear play pattern.
• Your loadout needs what Phantasma does well — check Mission Usefulness below before investing Forma.
• You’re ready to Catalyze / Forma it if you plan to main it on Steel Path.

Permanent investments on this weapon copy — separate from the Prime variant.

• Orokin CatalystCapacity

  Doubles mod capacity so endgame builds fit.

  Usually the first permanent upgrade on a weapon you plan to main.

• FormaPolarity

  Adds or changes polarities so matching mods cost half capacity.

  expect multiple Forma for a hungry config.

• Exilus Weapon AdapterSlot

  Unlocks utility options (Exilus on guns; melee focuses on stance polarity + utility mods).

  Install when you need ammo, handling, or QoL without sacrificing damage slots.

• Primary Arcane AdapterArcane

  Lets you install a weapon arcane for a strong passive bonus.

  Worth it once the base mod config is already solid.

• Riven ModRiven

  Unique rolled mod. Disposition 1.1.

  Chase clean desirable stats; skip awkward negatives on low-disposition weapons.

• Phantasma PrimeVariant

  The primed version — stronger stats and usually better polarities.

  Upgrade path when relics/parts are available.

Common building blocks for this gun — not a full ranked build, just the mods you’ll see most often.

• Galvanized Hell

  Multishot

  Core multishot for pellet weapons.

• Critical Deceleration

  Crit Chance

  Common crit-chance option on shotguns.

• Primed Ravage / Ravage

  QoL

Multishot

Usually the highest value damage slot — more projectiles, more procs, more clear.

Critical

Stack crit chance/damage when the weapon’s crit stats justify a crit suite.

Elemental

Faction/elemental lines for Steel Path; Viral+Heat is a safe default on many guns.

Fire Rate

Fire rate raises DPS but burns ammo — pair with reload/ammo economy when needed.
