Reduce

Reduce is the ability to break down a SR or SSR weapon or summon into materials. The option to reduce an item can be found from the Inventory status screen for that item. Items that are currently equipped to a party or that have been favorited cannot be reduced; remove the item from all parties and unfavorite it in order to see the Reduce button.

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. Items obtained from the Casino count as Premium for the purposes of reduction. Additionally, weapons with multiple upgrade stages have varying reduction payouts.

It costs rupies to reduce weapons and summons. This cost is lowered by 5% by Wonders obtained from chapters 52, 73, 83, 89 and 93 for Earth, Light, Fire, Wind and Water weapons and summons respectively. Player elemental skill mastery will increase the number of materials received from Reduce for premium SSR items.

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. As a notable exception, Normal Showdown Summons use relatively inexpensive 4★ uncap materials (most notably no Elemental Quartz), which means it is possible to reduce them for the equivalent of 5 copies at the cost of only 4, and earns you an extra 14 Quartz over reducing each copy individually with the best possible elemental skill bonus.

Weapon skill level have no effect on the result.

Reduction Recommendations

Summons

• Farmable SR Summon:
  • Omega SR - Transient value at the very start of the game. Keep a fully-uncapped copy until a stronger summon is obtained for that element. At that point, they can all be reduced.
• Premium SR Summon:
  • Carbuncle series - keep any copies you obtain. Multiple fully-uncapped carbuncles can be useful in some fights all the way into endgame.
  • Other SR - Reduce.
• Farmable SSR Summon:
  • Omega SSR - Reduce further copies after obtaining a fully-uncapped copy of the summon.
  • Side Story - Two fully-uncapped copies of each summon can be obtained from a side story. (One fully-uncapped from the start rewarded on completion of the story, and 4 copies from the shop to build another one.) It is usually safe to keep one fully-uncapped copy and reduce the other, but keep in mind there will never be a way to get more copies of that summon again. Verify on the summon's individual wiki page before reducing. If in need of quartz immediately, you may wish to reduce the copy awarded to you immediately, and build a replacement from shop copies later if necessary.
  • Normal Showdown Summons - Keep one fully-uncapped copy, and reduce any further copies. Consider saving extras to fully uncap a second copy to 4★ and reducing that for slightly more quartz at a minimal treasure expense.
  • Clash Event - Keep at least one fully-uncapped copy. Drops for clash event summons are very rare and shop copies are expensive, so consider carefully before reducing extras.
  • Event - Event summons vary in usefulness. It is usually safe to keep one fully-uncapped copy and reduce the rest, but some event summons are worth keeping multiple copies of for special circumstances. Check the specific recommendations at the time of the event running.
  • Demi Optimus Series Summons - reduce once you have obtained a fully-uncapped copy of the Optimus version of that element.
• Premium SSR Summon:
  Premium SSR summons are expensive and it is difficult to obtain a specific one without spending real money for Surprise Special Draw Set. They reward the best amount of quartz for reduction. Special consideration should be taken as to whether any premium SSR should be reduced. If in doubt and/or not in immediate need of quartz, don't reduce.
  • Non-Ticketable Summons shouldn't be reduced, unless you posses multiple fully-uncapped copies. This includes Dynamis Series Summons, Genesis Series Summons, and Providence Series Summons.
    • Optimus Series Summons are exception to that—once you obtain a fully-uncapped copy, any additional summons of same kind you obtain can be reduced.
  • Epic Summons should not be reduced.
  • Summons with Sub Auras - At least one fully uncapped copy should be kept. Others may be reduced if their call is not needed.
  • Other SSR Summons without a 4★ uncap - Premium Summons without a 4th uncap have the potential to significantly improve when their uncap is released, and should not be reduced until their uncaps are released and evaluated.
  • Other SSR Summons with a 4★ uncap - Can be reduced on a case-by-case basis. Check the individual summon's wiki page for a recommendation and consider your current and future team needs before committing to reducing.

Weapons

• Farmed SR Weapon
  • Very little value when reduced. Best used as skill fodder for Raising Weapon Skills.
• Premium SR Weapon
  • Reduce. If you like the look of a specific weapon, it can still be used as skin for an SSR weapon after you reduce it.
• Farmed SSR Weapon
  • Omega Weapons SSR from Omega and Impossible Omega raids - Keep weapons with ATK boosting skills until you have obtained a fully uncapped Basic Grid. Always keep any Celeste Claw Omega or Luminiera Sword Omega you acquire until you have 8-9 fully uncapped copies of each. Always reduce Colossus Blade Omega due to the rarity of Katana stones and the need for them in late game class unlocks. Other weapons may be reduced or used as skill fodder for Raising Weapon Skills as necessary.
  • Side Story - Reduce or keep on a case-by-case basis. Side story weapons usually do not see use into late game, but have some applicability in early-mid game grids. Up to two fully uncapped copies of each weapon can usually be obtained from a side story. It is usually safe to keep one fully uncapped copy and reduce the other, but keep in mind there will never be a way to get more copies of that weapon again. Check the recommendation on the weapon's individual wiki page before reducing. Pay special attention to side story weapons with a 4★ uncap, as several of these have continued usefulness into mid-late game.
  • Weapons obtained from Tier 1+2 Summon Raids and High Level raids should almost never be reduced.
  • Atma Weapons and Ultima Weapons should only ever be reduced if you cannot obtain any more cores to craft new ones.
  • Revenant Weapons should only ever be reduced as part of a planned process for Uncapping Eternals.
  • Showdown Weapons - Usefulness varies from weapon to weapon. Tribunal Thunder is the easiest Earth gun to obtain so Mechanic can be used for One Turn Kill purposes, and the HP-boosting weapons may see end-game use to meet HP thresholds for some fights. Evaluate based on your own personal needs.
  • Sephira Weapons are acceptable filler weapons for Omega grids, but can be reduced or used as fodder after that. Keep at least one Sephira Emerald Sword or Sephira Emerald Blade for Swordmaster use to deal Plain Damage. Reduce further copies of Sephira Emerald Blade due to ongoing need for Katana stones.
  • Beast Weapons - Most of these cannot be reduced. Of the reducable weapons, keep one of Anemoi Silver Lyre, Broadsword of Earth, Flohrenberk, Neptune's Trident and reduce the rest.
  • Xeno Weapons - Keep, do not reduce.
  • Trade Moon Weapons should never be reduced.
  • Event - Event weapons vary in usefulness, but most do not see any long term use except as a main weapon. It is usually safe to keep one fully uncapped copy and reduce the rest.
  • Cosmos Weapons - No more than one copy needs to be obtained of any one type. Reduce any further copies obtained to obtain the Azure Feathers.
• Premium SSR Weapon
  • Premium SSR weapons are expensive to obtain and difficult to obtain a specific one without spending real money, but also reward the best amount of stones from reduction. Special consideration should be taken as to whether any premium SSR should be reduced. If in doubt and/or not in immediate need of stones, don't reduce. Weapon stones are easier to obtain from farming than quartz and this should be kept in mind when reducing.
  • Grand Weapons should never be reduced.
  • Other SSR Weapons Without a 4★ uncap - Premium Weapons without a 4th uncap have the potential to significantly improve when their uncap is released, and should not be reduced until their uncaps are released and evaluated.
  • Other SSR Weapons With a 4★ uncap - Can be reduced on a case-by-case basis. Check the individual weapon's wiki page for a recommendation and consider your current and future team needs before committing to reducing.

In-game Help

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.
