Callis drops a bundle of items, and of the bunch, the Pistol, Queen's Rest, is really good. This is a fun Pistol for players who like that weapon type, as it fires high-speed rounds that have a 30% chance to spawn a Homing Sticky Projectile. Outside of the Pistol, players might want to farm Callis for the Class Mods she drops for each Vault Hunter to see if they work for their builds.

Callis is a simple fight, as her first health bar is Armor, so bring Corrosive and Cryo weapons to easily melt it. For her second health bar, she has Flesh, so Incendiary will do the trick. Callis will stomp around the arena with her metallic legs, and each stomp provides lava waves to watch out for. Callis can also behave like a spider and become invulnerable while she makes you fight Rippers, but simply waiting her out and damaging her again will ensure she's a fast and effective kill.
