There's also another type of Lost Ark Gold engraving. They all have a downside which could affect the speed of your attack or damage, defense or movement speed. I'll return to these jerks later .
After you complete the West Luterra portion that is Lost Ark, two slots in your profile's gear tab are opened beneath one slot, which is the weapon. Each of these can have engravings embedded inside. You'll see both equippable classes engravings and battle (or "combat") engravings in their submenumenus, which is accessible using alt-I. At first , you won't be able to equip anything, because you need to learn the recipes by reading them in books.
The relevant tutorial quest will give you some as well as a plethora of the green satchels that include recipes for engraving as rewards from sidequests East Luterra, and a few more after that in Tortoyk, Annika, and Arthetine. Engraving Recipe Pouches give random recipes, and engraving Recipe Selection Pouches permit you to select what they're made of and are best kept for when you've made a decision on the build you want to make. There are separate pouches that contain recipes for battle and class, too. (Sometimes these are classified as combat-related recipes, but they're the same as Battle recipes.)
Right-click on the books you get from pouches to best place to buy Lost Ark Gold find out the recipes inside. If you've got a stack of books, the alt click will allow you to utilize many at one given time, just like with any other stack of food items.
