Scorched Earth

Event: Scorched Earth is a public event in Fallout 76.

Quick walkthrough
Scorched Earth is considered the final act of the Fallout 76 storyline, in which the Vault Dwellers defeat the Scorchbeast queen and eliminate the source of the Scorched Plague. The event is triggered when Fissure site Prime is nuked by a missile from one of the Appalachian Automated Launch System silos.

Detailed walkthrough
Begin the quest by dropping a nuclear missile on Fissure site Prime, spawning a scorchbeast queen. Eight or more players are recommended for this difficult server-wide event, in which she must be killed within 30 minutes. During this engagement, waves of lesser enemies, including other Scorchbeasts, Scorched, and Scorched variants of most enemies will attack the player characters in addition to the danger of the queen herself, considering that there are several other fissures in the area around Fissure site Prime for Scorchbeasts to spawn from. Like all legendary enemies, the scorchbeast queen regenerates her health to full strength once before she is slain. Unlike her brethren, the queen's crop-dusting attack leaves a trail of powder blue or white radioactive dust in her wake instead of the usual green, which causes poison and radiation damage. Her shockwave attack can also summon various Scorched and Scorched Plague-infected creatures to draw attention away from herself, which can range from weaker enemies such as ticks, mole rats, rad-rats, and mongrels, to more powerful and dangerous ones like mirelurk kings and queens, gulpers, mega sloths, fog crawlers, deathclaws, or yao guai, possibly even legendary ones (With the release of patch 1.4.0.20, enemies that the Scorchbest Queen summons can now be of a higher level, increasing the difficulty). Combined with the support of other Scorchbeasts, this can cause many player characters to waste ammo dealing with the other enemies before turning their attention back to the queen. She can also spawn as a diseased version of herself, thus infecting player characters with the Blight if hit by her attacks.

Depending on which player characters dealt the most damage to her before the queen dies, they will be rewarded with various stabilized flux, caps, and experience at the completion of the quest, along with the various loot that can be recovered from the queen's carcass itself, which includes Ultracite crafting/mod plans, including those learned during Belly of the Beast, and Prime receiver mod plans for various weapons.

To aid with this quest, some player characters may deploy their C.A.M.P. or Survival tent nearby to act as a supply spot to unload junk, cook up food, and stash any extra weapons, armor, or other gear that is causing them to be over-encumbered for other player characters after slaying the queen as the one-way exit from the Glassed cavern has workbenches nearby to scrap junk if needed. If equipped with defensive turrets, the C.A.M.P. can also help take down the queen.
