The CALUS Mini Tool is a great PvE Solar weapon in Destiny 2, but how you obtain this weapon has changed slightly. You can now get the CALUS Mini Tool by completing the Presage exotic quest via the Exotic Mission Rotator. Learn more about using the Exotic Mission Rotator, as well as a few additional ways to pick up the CALUS Mini Tool, in the article below.

Best Ways to Obtain the CALUS Mini Tool

The most reliable way to get the CALUS Mini Tool is via the Exotic Mission Rotator, a feature added in Season 22. You'll need to wait until the exotic quest of the week is Presage, which has a chance of dropping the CALUS. Rarely, you can also find this weapon in Xur's or Banshee-44's shops.

1
Use the Exotic Mission Rotator to replay the Presage exotic quest. The Exotic Mission Rotator is a new feature added in Season 22 that allows you to play old Exotic missions. The only prerequisite is that you must own the expansion or season associated with that mission. To play Presage, you must own the Season of the Chosen or the Beyond Light DLC.^{[1]

- To access the Exotic Mission Rotator, go to the Destinations tab, then Legends. From there, you’ll see the weekly Exotic quest listed.
- If you’re playing the “Edge of Fate” expansion, you can access Presage by going to the Worlds Tab, then Legends.

Select the Presage mission when it's available. There are currently 5 missions in the Exotic Mission Rotator: Presage, Vox Obscura, Operation: Seraph's Shield, //NODE.OVRD.AVALON//, and Starcrossed/Encore/Kell’s Fall. The Exotic Mission Rotator changes once a week, so you can expect to see Presage available every fifth week.
- The Exotic Mission Rotator schedule can sometimes change, especially with the release of new expansions like “Edge of Fate.”

Complete the mission for a chance to get the CALUS Mini Tool. If you complete the mission on regular difficulty, legendary difficulty, and two runs on any difficulty, you are guaranteed three red border drops. Additional completions will still give rewards, but they're not guaranteed to be red borders.
- You can craft the CALUS Mini Tool once you get five red border drops of that tool.
