Oak Logs are crafting items used in tailoring and alchemy. They are the refined form of Oak Branches, created using 10 Oak Branches and 1 Sulfur. Their purified form is a Oak Plank. They are most easily created by purchasing a Refine: Oak Log recipe from a vendor, or acquiring the recipe from defeating a monster. Enemies rarely drop these, but the chances of enemies dropping these increase when you enter a trail with a level requirement of 20 or higher, and then increasing by tens. Below is a list of the different things you can craft with them.
