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 featured 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 Cryptids

 * Blue Devil
 * The Ogua

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.

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 could only be completed once. Each of the quests had a unique Blue Ridge themed reward. These rewards ranged from CAMP items to outfits.

Mothman Equinox
Point Pleasant has been transformed by a sect of the Mothman Cult who call themselves the "Enlightened." Join other Dwellers on the roof of the Mothman Museum every hour at the top of the hour to aid the Enlightened in performing a dark ritual to summon the Wise Mothman and earn the cryptid’s favor. Complete this event to earn specific Mothman Themed rewards such as the Cultist Incarnate Helmet, the Wise Mothman Throne and more!

The Mothman Equinox will be active from the following times:


 * Start : Tuesday, April 25 at 12:00 PM Eastern
 * End : Tuesday, May 9 at 12:00 PM Eastern

Improvements
In addition to the Once in a Blue Moon content, we’ve made a few other adjustments to the base game.

Expeditions
In this PTS playtesting phase, we have included some adjustments to Expeditions and their rewards. The following changes have been made:


 * Players no longer need to charge the Ultracite Battery to run an Expedition.
 * Fuel Quests are no longer mandatory before leaving for an Expedition and are now Daily quests with updated rewards that are more in-line with other Daily Quests.
 * Players can join an Expedition even if they haven’t finished the quest Responders Reborn but cannot start a mission as a leader until they have completed that quest.
 * Ashes to Fire now grants increased Stamps and Legendary items.
 * We’ve reduced the stamp cost from vendors on their items.

Workbench and Mod Descriptions
We’ve overhauled the way weapon and armor mod effects are displayed.
 * New Gameplay Setting: Show Advanced Mod Descriptions.
 * All mod descriptions have been updated to better reflect the effects the mod grants.

Item View and Inspection

 * AP cost and Damage Over Time effects are now shown.
 * We’ve added new icons to replace the + and – indicators when crafting new items.
 * Changes when modding are now color coordinated.
 * Set Bonuses now have an icon indicator next to the effect description.
 * Legendary effects now have the legendary star icon next to the effect description.
 * Extra effects not normally shown elsewhere are now displayed below the Legendary Effects.
 * Dynamic values have been added to show the current bonus.

Balance

 * The Bleedout Syringe Barrel now deals physical damage instead of poison.
 * Burning mods for Energy Weapons now deal fire damage.
 * We’ve adjusted the Two Shot Legendary Mod to deal its damage similarly to ballistic weapons. This is to keep the damage more in-line with one another.

Bug Fixes

 * The Sheepsquatch Shard special effect now works correctly.
 * The “Chance to Cripple” effect now correctly works on all weapons.

Update May 1, 2023

 * Enemies
