This is by no means a perfect or ideal guide but it should help you locate several legendary crafting parts for the legendary items.

Currently it isn't complete so feel free to leave comments describing the locations of the missing parts and also translating raid names to story mission names or vica versa.

Raid: Hunt Fire Giants

APPROX. LOCATION
After the first lava heat source and before the second lava heat source on the left there will be giant armoured ice golem. If you kill this giant armoured ice golem he drops the string.

Each weapon has three parts listed vertically.

The top part will drop earliest in the game near the start.
The middle part will drop somewhere in the middle of the game.
The bottom part will drop latest in the game near the end.

Make sure that before you craft any of these weapons you create a new save point. You can now craft the item safely and if it sucks reload you previous save from the "Load Game" menu in the game and give it another go.

If you are unfamiliar with how to do this

• Travel to any raid map.
  
• Then travel back to the village/base.
  
• This should create a new save point.
  
• Go back to the games main menu and select "Load Game".
  
• From here you should see a list of scroll-able save points.
  
• Pick the 2nd most recent to go back to your previous save point.
  
• Make sure you test this 2-3 times so that you are familiar with it before you try it for real.

As you likely saw my guide isn't complete and is lacking several parts, missingcorresponding raid/story mission names, incorrect monster classification/naming or might have the order of parts mixed up from top to bottom. Help me complete & correct it it by leaving comments.

If someone wants to use this guide to make a better guide for example with annotated screenshots showing exact locations etc. feel free to. If you only plan on making a sh*tty guide let's leave it at my sh*tty guide.
