Runecrafting in WildStar is the only way to customize your gear, attribute-wise. Almost every piece of gear has rune slots where you can put runes, and each rune gives a certain amount of one attribute – primary or secondary and some even grant powerful bonuses. You probably completed level 15 quest for runecrafting after you had visited your capital city for the first time, but honestly, that quest doesn’t explain the rune system completely. So let’s go over it one more time.
Everyone gets it at level 15, and there is nothing to level up, nothing to discover, no skill tree, talents, schematics… Pretty simple, craft and put runes in corresponding gear slots – fire runes into fire sockets, air runes into air sockets, etc. You do that at the engraving station in Illium/Thayd. Interacting with the station opens a screen with two tabs: Create Runes and Equip Runes.
