Enter Skyforge and its new equipment system, which is attempting to make gear both understandable and adaptable to the needs of each gamer. Each piece of gear has a certain number of main and secondary properties that it can equip (such as base damage or serial kill). These properties can be swapped for ones that a player desires more, allowing for hands-on customization.
Even better, gear can be leveled up in quality, from unusual up to mythic, by increasing its “integrity” meter. Each time the meter fills up, the gear is bumped up to a new tier and adds new property slots to utilize. Simple enough? Hopefully!
