Exotic Mission

Exotic Missions are a series of Quest Missions in Destiny 2 that serve as a means of acquiring certain Exotic Weapons. Many also feature secrets that allow players to earn unique cosmetic items such as Sparrows, jumpships, or Ghost shells.

Exotic mission rotator
Added in Season of the Witch, the Exotic Mission Rotator allows players to play a vaulted Exotic Mission, which rotates every week. Weapons associated with missions that enter the rotator will become craftable if they weren't already, and players will also be able to acquire weapons and armor from an associated season (not necessarily the one when the mission was introduced). Players will need to own the expansion tied to the mission or have previously purchased the season tied to the gear in order to play. Each mission can be played on Normal and Legendary difficulties, where Legendary completion is required to earn the Exotic Catalyst.

Rewards
Every completion of an Exotic Mission will grant the Exotic Weapon pattern for that mission, or an upgraded intrinsic trait for the weapon if the pattern is already unlocked.

On the first completion of each difficulty on a given week, the following rewards will be given:
 * A guaranteed Deepsight seasonal weapon
 * An unacquired seasonal armor piece, or a random seasonal weapon if all armor pieces are acquired

Players with a Xenology quest from Xûr will also gain extra progress towards the quest.

Trivia

 * Many exotic missions are considered secret missions, meaning they were added to the game without any prior announcement and are accessible through means unknown until the Destiny community discovers them.
