Weapon Memories

Weapon Memories are unique items that can be imprinted into Aspected Weapons using the Cosmoturgy Station. When imprinted into a weapon, it provides a passive buff when the weapon is in use. Up to three memories can be imprinted at a time without replacing old ones, and when a memory is imprinted, it is destroyed. Memories can be bought from the Astrologian NPC, dropped by different Bosses, or can be found in chests in certain Cosmic Voyages.
