Playstyle

Prisma crystals glisten in these electrified tonfas. Built as a crit melee / combo scaler option for squad clear and mission pressure.

Signature

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

When to Pick

  • You want a Melee that fits a crit melee / combo scaler play pattern.
  • Your loadout needs what Prisma Ohma 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.

Upgrades

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.

  • Stance / Exilus (as applicable)Slot

    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.

  • Melee 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 0.95.

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

Mod Scaling

Multishot

Melee doesn’t use multishot — invest in range, combo, and attack speed instead.

Critical

Blood Rush + crit damage is the classic crit melee route when base crit is workable.

Elemental

Viral/Heat or Corrosive/Heat dual-stats after your damage and conditioner mods.

Fire Rate

Attack speed (Berserker Fury / Primed Fury) keeps combo stacks rising.

Priority

Damage/CO → Blood Rush / Weeping Wounds → Crit Damage → Elemental → Range/Speed QoL.

Mission Usefulness

Mission / ContextRatingWhy
Steel Path Survival / Defense / DisruptionStrongTest whether Prisma Ohma still clears or enables clear when enemies are dense and overlevelled.
Exterminate / Capture Speed RunsStrongUse Prisma Ohma when its fire pattern matches fast tile clears — skip if it feels awkward on empty lanes.
Mobile Defense / ExcavationStrongHold objectives by deleting approach packs with Prisma Ohma, then reposition.
Open World / Long SightlinesSituationalLong sightlines favor hitscan/sniper/bow patterns over short falloff or melee.
Solo Boss / Single-TargetSituationalFine if Prisma Ohma has strong single-target multipliers; otherwise bring a dedicated boss weapon.

Acquisition

Check the How to Get table for blueprint / part drop sources.

Alternatives

Other options if Prisma Ohma isn’t the right fit.

  • Ohma

    Related variant in the same weapon line as Prisma Ohma — Ohma has lower damage (10%) and lower crit (50%). Compare polarities before Forma.

  • Ack & Brunt

    Another Melee if you want less crit than Prisma Ohma (Ack & Brunt: 20.0%).

  • Amanata

    Another Melee option if Prisma Ohma’s handling or acquisition doesn’t fit your farm.
