Weapons reduce into weapon stones corresponding to the weapon type, and high orbs and whorls that correspond to the weapon's element. Summons reduce into elemental quartz corresponding to the summon's element as well as various tiers of prisms. Farmable items such as raid drops and event rewards will reduce into fewer items than items obtained via Premium Draws.
It costs 2,000 rupies to reduce a farmed SR, 5,000 rupies to reduce a premium SR, 10,000 rupies to reduce a farmed SSR, and 20,000 rupies to reduce a premium SSR. Player elemental skill mastery will increase the number of items received from Reduce, but weapon skill level does not affect the outcome at all.
Uncapped items have the equivalent yield of reducing multiples of the same item; in other words, reducing 2 0★ SSR weapons gives you the same number of weapon stones, orbs, and whorls as reducing 1 of the same SSR weapon as a 1★ - both scenarios cost the same number of rupies as well. However, the elemental skill mastery bonus is solely per item, so, if you have a high enough skill to receive a bonus, you would receive more items from two 0★ items than the equivalent 1★ item.

|Elemental reduction allows weapons and summons of rank S rare and higher (with the exception of Archangel equipment, Rusted weapons, and others) to be exchanged - along with a rupie fee - for specific treasures. Having a higher elemental upgrade skill increases the number of treasures received, as well. To reduce weapons and summons, visit the individual status screen for the item you want to reduce.|
