Once in a Blue Moon

Once in a Blue Moon is the 16th major update for Fallout 76, following Mutation Invasion. It released on June 20, 2023, alongside Season 13 Shoot for the Stars.

Features
The update introduces two new Cryptids, Public Events, Side Quests, Rewards, a Daily Ops Mutation, and the start of Season 13: Shoot for the Stars. The PTS began on April 21, 2023.

New Public Events
Every 20 minutes, one of the following Public Events appeared on the map:
 * Safe and Sound: Blue Ridge has renovated the Middle Mountain Cabins to be their latest and greatest Brahmin pitstop, but they just can't seem to keep the local critters at bay. The Repeller Speaker system they use to repel the creatures and keep their Brahmin safe has been damaged. To retake the pitstop and create a safe haven for their Brahmin to rest, they will need your help! Clear out the creatures, defend the Repeller, and the Blue Ridge Caravan will reward you handsomely for your assistance!


 * Beasts of Burden: After a trade deal goes wrong, Luca Costa finds himself in need of some help. A group of local Cultists has stolen his Brahmin and cargo of makeshift explosives. His Uncle Vinny will not be happy if he catches wind of it. Be extra careful not to disturb the local wildlife, however, as Cultists have recently noticed strange rumblings in the woods nearby.

New Cryptids
The update introduces the Blue Devil, a massive dog-like creature, and the Ogua, an aquatic and armored enemy.

Daily Quests
Costa Business Daily Quests: Resident grouch and taskmaster, Vinny Costa, hasn't been happy with the performance of his employees lately, and he'd be happy to throw some caps at anyone willing to solve the problem. Players can learn all about what has the caravanners' boots stuck in the mud, and collect some unique rewards along the way, in this series of one-off daily quests. The series of 7 quests can only be completed once. Each of the quests had a unique Blue Ridge themed reward, which ranges from CAMP items to outfits.

Daily Ops
A new enemy mutation, Danger Cloud, affects maximum AP and its regeneration rate.
