Cosmos Weapons are weapons designed to empower teams with several weapons of the same type equipped. (This should not be confused with Ultima Weapons, which empower teams with characters of a single weapon specialty.) They are obtainable from the Shop and from Grand Order (Raid) share chests. Cosmos weapons have two skills which vary depending on the type of the weapon. They have no skill levels to raise and multiple Cosmos weapons' effects do not stack.[1]
All Cosmos weapons are obtained at 3★ and reduce for 
Azure Feather ×2 and Weapon Stone ×4 (matching the weapon type).
