In the Milepost Zero Update on September 3rd, 2024, the legendary cores were removed from the game. Previously, these were given as rewards at public events. Now there are legendary modules instead. For the new legendary crafting, we now need more modules and through the events we now get significantly more. In addition, the weight of the modules has been changed from 0.25 to 0.15 (with Pack Rat Perk even only 0.04) and the modules now count as junk (so they can be put in the scrapbox). If you don't have Fallout 1st, you can simply carry the modules with you. The modules cannot be dropped and you don't lose them if you die in the game.

If you want to farm legendary modules very efficiently and quickly and have a small team of players, you can farm the “Encryptid” event very well.

To start Encryptid, you need an Assaultron Recall Keycard, which you can buy from all vendors at train stations. After purchase, it must be crafted at a tinker workbench using Flux. You can only buy the key cards once you have completed the “Van Lowe” questline. Read the posters at the train stations showing the sheepsquatch and the inscription “sheepsquatch ate my brother”.

You start the event at the “Pylon Ambush Site” in Ash Heap (southeast of Rusty Pick). The event has a cooldown of around 3 hours and is therefore not always guaranteed to start on public servers.

To farm Encryptid with Fallout 1st (private server), follow these steps:

    Form a team with players who have a few of Aggressotron Recall Key Cards ready
    One of you starts a private server (Fallout 1st)
    (Make sure that the others can join you. So either form a team in the main menu or set the server to "Friends")
    Gather at the pylon ambush site
    Start the event
    Receive 5 Legendary Modules upon completion
    Now you leave this server
    Another player on your team starts a new private server
    You all join together again and start the event again
    This way you can start a series of private servers (2 players with Fallout 1st are enough) and start the event immediately every time.

If you're quick, you can farm up to 60-70 legendary modules per hour.

If you don't have a team ready at the moment and want to farm legendary modules at the same time, that's also possible. Pay attention to which events you do and trigger yourself.

    Only plays public events
    Trigger Encryptid in public as often as you can
    Find servers without nuke zones and launch nuclear bombs on the Queen (2 legendary modules) or Earle (5 legendary modules) between public events (on the hour, 20 after and 40 after).
    For example, look for via Discord Groups that do Queen Runs and join there to participate, like we do: Nuka Knights Discord
    The more endgame events you play, the faster you will get legendary modules
