Craftable sets are able to be made in all styles and for all levels. Craftable set bonuses may be applied to any player made armor item. Jewelery items (necklace and rings) are not player craftable at this time. Some craftable sets scale with your level, some are set percentages. For scaleable sets the items must be made for the same player level in order to count for the set bonus. I am unsure as to whether set bonuses can be attained with different level items that use a percentage based skill. For clarity’s sake all stats given are for Veteran Rank 12 armor and it will be noted if they are scaled for lower levels or not.
In order for a crafter to be able to add a set to a crafted piece of armor they must have researched a certain number of traits for that item. Set items may only be crafted at certain workstations which are listed with the set information below.
