Reward Chests

When you defeat an enemy, it may drop chests from its Drop Table; each chest on the table has a drop rate and loot list:

• The drop rate (0.01% - 100%) determines if the chest drops (ie. some chests drop very rarely; others may drop every time)
• The loot list is the list of possible items the chest contains (eg. Low Orb, High Orb, Rupees)

The game rolls twice for each individual chest:

• First: whether or not the chest drops (Yes/No)
• If yes: which item the chest contains (one item on the chest's loot list)

Normal chests appear as Wooden, Silver, or Gold depending on the exact item rolled/contained.

Special Red chests are guaranteed drops for certain players in Raid and Co-Op battles:

• Host chest (awarded to the player who started/hosted the battle)
• MVP chest (awarded to the player who gained the most honors)
• Vice-MVPs (players who gained 2nd or 3rd most honors; certain raids have this requirement boosted to 4th, 5th, and 6th most honors) receive more varied rewards

Blue Chests are rewarded based on contribution. Getting more honors during the raid linearly increases the drop rate. Blue Chest are available in various raids, such as Grand Order (Raid), Proto Bahamut (Impossible), Impossible Omega Raids, Impossible Omega II Raids, The Four Primarchs (Impossible), Akasha (Raid) and Lucilius (Raid).

Most chests have internal drop rates, causing some items on their loot list to drop more or less often. As a result, some items are rare due to the rarity of the chest that contains them, while others are rare outcomes from common or even guaranteed chests. The main difference between them is that the former can benefit from drop rate boosts.

Drop Rate Boosts

Drop rate boosts have no effect on which item you receive from a given chest, only whether or not a chest appears.

The table below contains all verified drop rate boosts. Optimal boosts have been highlighted for quick reference.

Dragon Bar V	~3%	At SL10. Despite showing +2, multiple copies do not stack.
Septian Burner (mainhand)	~3%	At SL10. May be below 2.5%.
Snowflake (mainhand)	~3%	At SL10
Oliver (mainhand, all stages)	~5%	Includes Rebirth, Ventus, The Storyteller, etc.

Mechanics

As drop rate boosts only affect the chance a chest will drop, guaranteed chests (including Host and MVP chests) do not benefit from drop rate boosts at all. Chest contents are unaffected by drop rate boosts.

Drop rate boosts are multiplied against the base drop rate of a chest. A 1.5x drop rate boost would cause a chest with a base 2% chance of dropping to instead have a 3% chance to drop.

When farming items with higher base drop rates, drop rate boosts have a more noticeable short-term impact, but they can be equally (if not more) valuable for farming rarer items over a large number of attempts. Either way, drop rate boosts are especially valuable when leeching, as the majority of drops will come from non-guaranteed chests rather than Red chests.

The Drop Rate Boost Formula is as follows:

   (1 + Weapon Skill + Main Summon Aura + Friend Summon Aura + Tien + Dragon Bar V)
   * (1 + Crew buff)
   * (1 + Journey Drop buff)
   * (1 + Bounty)
   = Drop rate multiplier

So the best theoretical drop rate boost would be:

   (1 + 0.075 (4★ Damascus Knife) + 0.25 (3★ Kaguya) + 0.25 (3★ Kaguya) + 0.1 (5★ Tien)+ 0.03 (SL10 Dragon Bar V))
   * (1 + 0.2 (Lvl 3 Weather Vane))
   * (1 + 0.2 (during double JD))
   * (1 + 0.7 (BH10))
   = 4.174x

Drop Rate Boost Cap

Even though a boost of 4.174x is theoretically possible, the Drop Rate Boost multiplier is capped at 3x. Thus a base 1% drop rate can at most be boosted to 3%.

Because anything past 3x is wasted, one can skimp on some boosts:

   3 / (TH * JD * Crew) = additional multiplier needed from equippables (weapons, summons, characters)

   3 / (TH9 *  JD * Crew)
   3 / (1.5 * 1.1 *  1.2) = 1.52x needed from equippables
   
   3 / (TH9 * JDx2 * Crew)
   3 / (1.5 *  1.2 *  1.2) = 1.39x needed from equippables

Some example combinations of equippables needed to reach cap based on above examples:

   1.52x needed:
   1 + 0.25 (Kaguya) + 0.25 (Kaguya) + 0.05 (Oliver) = 1.55x
   1 + 0.25 (Kaguya) + 0.25 (Kaguya) + 0.03 (Dragon Bar V) = 1.53x
   1 + 0.20 (Kaguya) + 0.20 (Kaguya) + 0.1 (Tien) + 0.03 (Dragon Bar V) = 1.53x
   1 + 0.20 (Kaguya) + 0.15 (Rabbit) + 0.1 (Tien) + 0.05 (Oliver) + 0.03 (Dragon Bar V) = 1.53x
   
   1.39x needed:
   1 + 0.25 (Kaguya) + 0.1 (Tien) + 0.05 (Oliver) = 1.4x
   1 + 0.20 (Kaguya) + 0.20 (Kaguya) = 1.4x
   1 + 0.15 (Rabbit) + 0.15 (Rabbit) + 0.1 (Tien)  = 1.4x
   and so on...

Vice-MVP Rewards

The Vice-MVPs (players with 2nd and 3rd highest honors or 2nd to 6th highest honors depending on the raid) in a raid receive either:

A copy of the red MVP chest:

• Its content and internal rates are identical to a "normal" MVP chest.
• The probability to obtain it is estimated to 40% in 2nd place, and 20% in 3rd place and beyond (when applicable).
  • This probability is not affected by drop rate boost.

A unique Vice-MVP chest which drops one normal (non-Host/MVP) chest from the drop table:

• The exact chest is selected by rolling for each chest in order (see diagram) using their regular drop rate.
  • Because of that, the selection process will never go beyond a chest that is guaranteed to drop.
  • This drop rate is affected by drop rate boost.

In short: Vice-MVPs can potentially receive almost anything on the drop table except the Host chest.

Blue Chests

Blue Chests, also called special loot chests, are a special form of reward chest which is awarded based on contribution to the raid. Unlike the MVP and Vice-MVP chests, a Blue Chest doesn't require a high ranking in the raid. Instead, its drop rate is proportional to the amount of honor obtained. It starts at 10% chance to drop for 1 honor, and increases linearly up to 100% chance once a certain amount of honor is earned. This amount of honor depends on the raid, and is a fraction of the total honor obtained by all participant in the raid:

• For Impossible Omega Raids, an approximate 18.5% of the total contribution to the raid is needed to guarantee a blue chest.
• For Impossible Omega II Raids, an approximate 8% of the total contribution to the raid to guarantee a blue chest.
• For Impossible Tier 3 Summon Raids, an approximate 6% of the total contribution to the raid is needed to guarantee a blue chest.
• For Akasha (Raid), an approximate of 12.5% of the total contribution to the raid (about 1,500,000 Honor) is needed to guarantee a blue chest.

Because most honors are obtained by dealing damage, the required amount is usually close to that percentage of the boss HP, divided by 100. However, that value can increase, as raid-wide buffs, debuffs and healing also award honors. Bosses can also have "optional" HP when there are multiple targets that are not all required to be killed, such as Tiamat Impossible or Grand Order (Raid).

Flip Chests

Some item drops (usually high-quality treasures or SSR items) result in a special animation: a gold chest that performs a little flip under a rainbow while playing a special sound.

• Contrary to popular belief, flip chests are not separate types of chests and do not even necessarily represent rare drops
• Some chests (such as those containing SSR Omega Weapons) do only contain items that result in the flip animation (causing the above misconception), but many chests contain some items which will result in a flip and others which will not (see example table below)
• For a list of some items which result in the flip animation, see Flip Chest Contents

Share Chests

Share Chests are awarded to the Host (Discoverer) of certain raids (such as Grand Order, HL Proto Bahamut, and Impossible Tier 1 Summon Raids).

• A Share Chest has two or three slots; each slot rolls to determine which (if any) items are available.
• The host and each member of their crew who participated in the battle may select one available item to roll on.
  • If nobody from the host's crew participates in the battle, the host can still select an item from the share chest.
• Player rolls range from 1-999 and cannot tie; whoever rolls highest on an item receives it. Roll values are also random and have no correlation to raid honors.
• The Share Chest lasts 10 minutes or until all players have rolled, at which point remaining items are forcibly distributed or discarded.
• A player cannot receive more than one item even if some items are unclaimed.
• A player cannot be part of more than one raid with a Share Chest active at a time.
• Due to the material cost of hosting raids with Share Chests, it is usually considered bad etiquette to roll against the host unless explicitly invited.
• Players can pass on Share Chest contents if no items are desired or an item was rolled for by mistake.

Reading Drop Tables

It is often difficult to tell in-game what a chest contains (or even which chest dropped). Drop tables help demystify which items are guaranteed, rare, or compete with one another, which is useful for better projecting acquisition rates for particular items or the usefulness of drop rate boosts for particular battles.

• Enemies without sufficient chest-specific drop data have drops sorted by chest aesthetic (Wooden, Silver, Gold, Red)
• The sample drop table below is from Grand Order (Raid):
  
  

Chest 1	Chest 2	Chest 3
100%	100%	100%

Source SSumiwatari; host box updated during 5th anniversary Drop table last updated: 2019-03-10, all stated drop rates are estimates. The game changes over time. If the drop tables become incorrect please notify the wiki staff.

Analysis

• Chest 1 always drops, will always contain a Heavenly Horn or an Omega Fragment and plays the flip animation
• Chests 2 and 3 always drop and have larger item lists: the Blue Sky Crystal and Supreme Merit are rarest and play the flip animation
• Chest 4 always drops, contains one Azure Feather and plays the flip animation
• Chests 5 drops most of the time and always contains either a normal or Omega Anima
• The Host and MVP chest each contain only one item, meaning the Host always gets a Silver Centrum and the MVP always gets a Heavenly Horn

Conclusions

• 4 chests drops are more common, and contain a guaranteed Azure Feather
• Drop rate boosts only increase the rate of normal and Omega Anima
• Unless all six normal chests drop, a flip chest could be any of: Heavenly Horn, Tier 1 Summon Omega Anima, Blue Sky Crystal, or Supreme Merit

Drop rate values

Tables will often have drop rate values listed.
When there is a large sample of data a percentage may be given but most of the time a vaguer term will be used:

Label	Rough drop rate
100%	Guaranteed drop
Likely	70% - 99%
Common	35% - 70%
Uncommon	15% - 35%
Very Uncommon	7% - 15%
Rare	3% - 7%
Very rare	1% - 3%
Extremely Rare	<1%
