Damascus Ingots are Power-Ups which can be used to uncap most weapons by one star.
Due to their extreme scarcity, Damascus Ingots should only be used to uncap very rare and powerful weapons, usually weapons with 4★ uncaps that require real money to reasonably obtain (as the Ingot substitutes for a duplicate of the weapon).
- Limited Premium Draw Character Weapons (aka. Grand Weapons), such as and
- Moon Weapons such as and and "Grand" Weapons (character weapons for limited characters)
- Farmable weapons (including Event weapons) should never be uncapped with Ingots.
- While Ingots can also be used in lieu of materials for 4★ upgrades, this is also discouraged as such materials can be farmed more reliably than duplicates of other valuable weapons.
- Consider asking your crew or the community if unsure about a particular weapon.
