How to Unlock the Legendary Rainbow Vomit Shotgun

Rainbow Vomit is a fun and colorful Shotgun that fires a variety of elemental shots. The elemental types actually vary depending on the individual roll of the item.

It's a great catch-all for builds that boost general elemental damage, and also allows you to take on enemies without needing to always swap-out for the appropriate Weapon.

Unlock Location:

• Travel to Carcadia City in Carcadia Burns.
• Start the side quest chain beginning with Enter the Electi.
• Finish the last quest (The Mole’s Gambit) to unlock Leader Willem.

Farm Method:

• First-time fight against Leader Willem happens during the questline.
• After quest completion, revisit his arena.
• Use the Encore Machine to respawn him.
• Farm until Rainbow Vomit drops with your preferred elemental loadout.
• To see what other items Leader Willem drops, visit his boss page
