Kulstar GUIDE

Understand Kulstar

Useful when…

  • Considering the distinct explosive and projectile attack entries when using an explosive secondary.
  • Accounting for a three-round magazine and 2-second reload.

Rocket and cluster attack entries

Rocket Impact is a projectile with 200 Impact damage. Rocket Explosion lists 300 Blast damage, with falloff starting at 0 and ending at 3.9 meters and 40% reduction. Cluster Bombs are listed as projectiles at speed 8 with 75 Impact damage. Cluster Bomb Explosion separately lists 90 Blast damage, with falloff starting at 0 and ending at 3.9 meters and 40% reduction. The entries do not establish that cluster projectiles are produced by the rocket or that they hit the same target.

Handling

The trigger is listed as Active, fire rate as 2, magazine size as 3, and reload time as 2 seconds. Rocket Impact lists projectile speed 100, while Cluster Bombs list speed 8; units are not provided. Each attack entry lists 17% critical chance, a 2.3× critical multiplier, and 19% status chance. The weapon has a Vazarin polarity.

Requirements and alternatives

Kulstar requires Mastery Rank 5 and has a rank cap of 30. The listed build price is 30,000 credits and the blueprint cost is 40,000 credits; the components include a Kraken weapon component. Pyrana is described as an automatic hand shotgun, while Zylok is described as a double-action pistol. Their descriptions do not specify the multi-stage explosive attack entries listed for Kulstar.

Limitations and tradeoffs

  • The magazine holds 3 rockets and reloads in 2 seconds.
  • Cluster Bombs are listed at speed 8, compared with 100 for Rocket Impact; units are not specified.

Common mistakes to avoid

  • Adding all attack-entry values into a single guaranteed damage figure.
  • Assuming cluster projectiles are produced by the rocket or hit the same target.
