Flavors of Mayhem

Flavors of Mayhem is a main quest in Fallout 76.

Detailed walkthrough
After completing Signal Strength, Rose will task the Resident with learning the tactics used by the five raider gangs that once existed in Appalachia to see which works the best.

Cutthroats
The first gang Rose tasks the Resident in following in the footsteps of is the Cutthroats, who used the weakening chem Karma against their enemies. Rose will give the Resident Rose's syringer and ask them to modify it with a Karma syringe barrel mod. After adding the mod, one is instructed to shoot a yao guai with Rose's syringer and then kill it while it is under the influence of Karma.

Trappers
The next gang whose tactic must be learned is the Trappers. As their name suggests, Trappers were known for using a variety of traps, and Rose instructs the Resident to go to the Sons of Dane compound, where they will find the ingredients needed to build explosive bait. After finding the ingredients and crafting explosive bait one must use it to kill an enemy.

Diehards
Rose will then bring up that one of the gangs, the Diehards, were not like other raiders because they were against unaggravated killing, and that if they had any tactic it would be making friends. Rose will then send the Resident to "make friends" with a deathclaw. Getting in proximity to and interacting with the deathclaw causes it to attack, with Rose stating she didn't actually think the player character would do it, and give the options of either fleeing from the deathclaw or killing it. The deathclaw can be dead, resulting in a long wait time for a spawn.

Blackwater Bandits
Following the encounter with the deathclaw, Rose will mention the Blackwater Bandits' thievery expertise and tasks the Resident with stealing a weapon from a super mutant camp, from Relay tower HN-B1-12 or Summersville. While Rose emphasizes the gang's use of stealth, it is not required to steal the weapon without being spotted.

Gourmands
The final gang to be emulated is the Gourmands, who Rose remarks as being cannibals and sends the Resident to kill a group of Feral Ghouls and eat one. After killing the ghouls, Rose will comment that she won't make anyone eat another human or ex-human, and the optional objective to cannibalize the ghoul appears. Regardless if one eats the ghoul, Rose tells the Resident to return to the Top of the World for their reward and the next part of the Raider questline, Key to the Past.

Bugs

 * Sometimes, even with the right equipment, you cannot craft explosive bait.
 * Sometimes the marker will not appear on the map and the player character will have to visit both camps of Blackwater Bandits or reconnect, another fix requires the player to request the quest location in the Pip-Boy menu.
 * Sometimes a weapon cannot be found in the camp's weapon stash this can simply be fixed by adding the player's weapon into the container taking the weapon back.
