Bo Prime GUIDE

Understand Bo Prime

Useful when…

  • Use its normal attack for impact-heavy melee strikes.
  • Use the slam modes when you want area damage around the landing point.

How its attacks differ

The normal attack lists 176 damage: 158.4 Impact and 17.6 Puncture, with 24% critical chance, a 2.6× critical multiplier, and 32% status chance. A regular slam deals 352 Impact as an area attack, with damage falloff from 0 to 6 m and 50% reduction at the listed endpoint. A heavy slam deals 528 Blast over an area with falloff from 0 to 8 m and 30% reduction. The listed attack range is 3 m; its heavy attack has a 0.5-second wind-up.

Investment and fit

Its 24% critical chance and 2.6× multiplier give critical-focused upgrades a reasonable starting point, while the 32% normal-attack status chance also supports status-oriented choices. These are build directions, not promised final damage. The weapon has Vazarin and Madurai polarities, which can help match compatible mods to those slots. Consider whether you prefer its staff handling and predominantly Impact normal damage before investing heavily.

Alternatives and cautions

Dakra Prime is a sword with a higher listed critical chance (36%) but requires mastery rank 10. Fang Prime is a dual-dagger option with 26% critical chance and a 2.6× multiplier, also at rank 10. Glaive Prime is a glaive and its description identifies thrown use at distance; the supplied comparison does not provide attack figures. These candidates suit different weapon handling, so the listed stats alone do not establish a direct upgrade. Do not confuse the 528-damage heavy slam with the normal attack or regular slam.

Limitations and tradeoffs

  • Normal strikes are heavily weighted toward Impact, with no listed Slash damage.
  • Heavy slams have a 0.5-second wind-up.
  • Comparisons provide only selected facts and do not establish overall superiority.

Common mistakes to avoid

  • Treating regular slam and heavy slam as the same attack; their listed damage types and values differ.
  • Assuming the Prime and Vaulted tags establish current acquisition availability.
