Jat Kusar

Blade-and-whip melee weapon

Released Jul 26, 2017

Jat Kusar is a mastery-rank-11 blade and whip with a strong critical profile, innate Heat damage, and a charged strike described as producing an explosive blast at range. Consider it when you want a melee weapon whose normal hits and slams already include Heat, while recognizing that its charged ranged behavior is distinct from those attacks.

Jat Kusar GUIDE

Understand Jat Kusar

Useful when…

  • Close-range melee with a mix of physical and Heat damage.
  • Using its charged strike for an explosive ranged hit when that attack behavior is useful.

Attacks and damage

Normal attacks deal 79 Impact, 45 Slash, 13 Puncture, and 81 Heat damage. They have 35% critical chance, a 2.5× critical multiplier, and 19% status chance. The standard slam is a separate area attack dealing 436 Heat damage out to 7 m, with 50% falloff. The heavy slam deals 654 Heat damage out to 8 m, with 30% falloff. The description also identifies a charged strike that ignites an explosive blast at range; the supplied attack figures do not specify that charge attack's numeric damage, so the slam values should not be used for it.

Handling and mod fit

The listed normal attack speed is 0.833, melee range is 2.4 m, and heavy-attack wind-up is 0.4 seconds. Its 35% critical chance and 2.5× critical multiplier support considering critical-focused upgrades; the 19% status chance and existing Heat damage also make status-focused choices plausible, depending on your build. Two Madurai polarities can accommodate matching mods. These base figures do not determine a final build or damage result.

Choose by attack behavior

Jat Kittag is a mastery-rank-5 hammer with Impact-heavy normal hits and Blast-damage slams, so it suits a different attack profile. Tak & Lug is a sword and shield whose unique heavy attack throws its shield across a wide area; Vastilok is a gunblade with a heavy shotgun attack. Consider those only if those weapon types and attack behaviors fit what you want.

Limitations and tradeoffs

  • Mastery requirement 11 is higher than the compared Jat Kittag's rank 5.
  • Attack speed is 0.833; the listed normal range is 2.4 m.

Common mistakes to avoid

  • Do not cite the slam's Heat damage as the numeric value of the charged ranged blast; no charge damage figure is supplied.
  • Do not confuse the standard slam and heavy slam: their damage, radius, and falloff differ.
