The entrance to the Collection Vault can be found in the main menu and the Commander interface as follows:
Collection Points are increased by obtaining Skin NFTs. When collection points reach a certain level, you can earn collection titles, which provide power bonuses.
There are corresponding entrances for the Headquarters, Frame, March Slot, Nameplate, and Guardian outfits. Clicking these will take you to the illustration interface.
In the illustration interface, you can view all the outfits of the same category, and you can see the ownership status of each outfit. The same outfit can be owned multiple times. Clicking on any illustration will take you to the preview interface of that outfit.
In the preview interface, you can see the attack bonuses and collection points provided by the outfits you own and do not own, as well as the NFT number. Acquiring additional identical skin NFTs can contribute to your collection and attack points, though the combined benefit is constrained by an upper limit.
Some outfits form a set. When you obtain more than two of the outfits, you can get Attack bonuses. If you collect all the outfits in the set, you unlock the series collection rewards and earn additional collection points. Additionally, collecting a certain number of complete sets will unlock stronger Attack bonuses.
