Kuva Grattler GUIDE

Understand Kuva Grattler

Useful when…

  • Comparing its automatic explosive-shell pattern with standard Grattler.
  • Considering its listed capacity, reload, and attack-component values for Arch-Gun use.

Projectile impact and explosion

The projectile-impact entry lists 9.4 Impact, 9.4 Slash, and 75.2 Puncture; the separate explosion lists 155 Blast. Both entries list 27% critical chance, a 2.1× multiplier, and 27% status chance. Projectile speed is 250 and firing rate is about 5.55 shots per second. The explosion’s falloff ends at 9 metres, with 70% reduction at that endpoint.

Capacity and mastery

The magazine holds 60 rounds and the listed reload is 4 seconds. Standard Grattler has a listed 30-round magazine and 4-second reload. Kuva Grattler has three base Madurai polarities and requires mastery rank 15; standard Grattler requires rank 4. Capacity and reload are handling facts; the firing rate is listed separately at about 5.55 shots per second.

Related weapons

Standard Grattler is the lower-mastery explosive-shell option. Larkspur’s description calls its normal attack a wild initial attack that locks on and chains to nearby targets, and describes a separate explosive projectile mode. Cortege is described as a heavy flamethrower with explosive secondary projectiles. Their descriptions identify different patterns; Kuva Grattler’s instantaneous maximum-fire-rate description does not remove the listed reload or projectile speed.

Limitations and tradeoffs

  • The listed firing rate is about 5.55 shots per second, alongside a 60-round magazine.
  • Reload takes 4 seconds.
  • Explosion falloff ends at 9 metres with 70% reduction at that endpoint.

Common mistakes to avoid

  • Interpreting instantaneous maximum fire rate as hitscan accuracy.
  • Ignoring the 4-second reload when considering its 60-round capacity.
  • Calling the 9-metre falloff endpoint a blast radius.
