With games like this, I always like to know which items I should keep because they might be useful later on, and which items I can sell because they are useless or because they are used for things my character build won't need. Risen 3 is the first game I didn't find any information about that, so I started to collect the information while I played. Now that I'm done, I think some people may find this information useful, so I post it here.

Just to be clear about what this guide is NOT:
- where to find ingredients or crafting recipes -> I suggest http://forum.worldofplayers.de/forum/threads/1378617-Risen-3-Game-Hints-(Permanent-Potions-Recipes-Items)-Possible-Spoilers-*Under-Construction*
- a list of all the weapons in this game, because you'll only find the craftables here. I refer you to http://risen.gamepedia.com/Category:Risen_3_weapons and such.

What this guide should do is allow you to perform a simple 'search' command to check if the lootable item in question is used in any crafting and if so, if it's an item you may or may not want to craft. This will determine if the item is safe to sell or if you may want to keep some of them for future crafting. As a side effect, this will also be an overview of all craftable items in Risen 3.
