Note that if only four nodes have been lit Lost Ark Gold, engraving won't be able to be able to have any effect. And if you manage in accumulating enough bonuses to light fifteen nodes in total, the additional will not have any effect.
There's also another type of engraving. They all have a downside and might reduce your attack speed as well as damage, defense or even your movement speed. I'll get back to these jerks a bit later.
Once you've completed the West Luterra portion from Lost Ark, two slots in your profile's gear tab will open beneath that slot for weapons. Each slot can be equipped with an engravings embedded within them. There are equippable class engravings and battle (or "combat") engravings in their submenu, which you bring up when you press alt-I. At first , you won't have any equipment to use, since you'll need to learn the recipes by reading them in books.
The relevant tutorial quest will provide you with some as well as a plethora of green satchels which have recipes for engraving to complete the sidequests East Luterra, and a couple more to Tortoyk, Annika, and Arthetine. Engraving Recipe Pouches give random recipes, and engraving Recipe Selection Pouches allow you to choose which recipes they contain and are best kept for when you've made a decision on the type of build you'll be using Lost Ark Gold for sale. There are separate pouches that contain classes and battle recipes too. (Sometimes the latter will be called 'combat' recipes, but they're identical to battle recipes.)
