Ohma GUIDE

Understand Ohma

Useful when…

  • Normal tonfa attacks with a large Electricity component and 30% status chance.
  • Electricity regular slams and Blast heavy slams as distinct area modes.

What does each attack mode do?

Normal attacks list 224 total damage: 110 Electricity, 76 Impact, and 38 Slash. They have speed 0.917, 15% critical chance, a 2× critical multiplier, and 30% status chance. The regular slam is a separate area attack with 448 Electricity damage and 50% falloff by 8 m; heavy slam deals 672 Blast damage with 30% falloff by 9 m. Listed range is 2.5 m, follow-through 0.6, and heavy-attack wind-up 0.7 seconds.

What investment priorities make sense?

Its 30% status chance and substantial Electricity component make status-focused investment a reasonable option to consider. Its 15% critical chance and 2× multiplier also permit a critical direction, though the listed starting chance is lower. It requires Mastery Rank 8 and has no listed polarity. The recipe requires a blueprint, 2 Argon Crystals, 15,000 Ferrite, 4 Alertium, and 1,400 Plastids; build time is 43,200 seconds.

What distinguishes it from the comparisons?

Prisma Ohma shares the tonfa class and has higher listed critical statistics in its comparison entry, but those values alone do not show its full attack behavior. Shaku is a nunchaku described as especially fast, while Coda Pathocyst is a glaive with an occasional miasmite effect while in flight or on contact. Those handling and effect differences make them distinct candidates, not interchangeable versions of Ohma.

Limitations and tradeoffs

  • 30% status chance and a large Electricity component.
  • 15% critical chance; the listed profile is not primarily high-critical.
  • Normal, regular slam, and heavy slam use different damage mixes.

Common mistakes to avoid

  • Do not attribute the regular slam's Electricity damage to the heavy slam, which is listed as Blast.
  • Do not treat Prisma Ohma's comparison stats as proof of its full attack behavior.
  • Do not confuse tonfa handling with Shaku's nunchaku class.
