The adventure journal (N) is broken up into 10 categories,all of which contribute to the total completion (100%) of an area. Click the drop down from the banner above for a specific area.
These items drop from any killed mobs, be it in the field or in an areas dungeons (normal or hard). Once picked up simply right click the item in your inventory to consume the item and add progress to your Adventure Journal. Note: many of these require more than one.
Cooking items also go into the inventory like collections,but instead of consuming them the player must take the items back to the Chef in the area. The Chef will combine the individual ingredients and give the player an item that can be consumed for completion.
These are spread out through every zone in an area, simply go up and press (R) on them.
