Blue Chest Setups
Blue chests are awarded based on the amount of honors achieved in a raid maxing out at 99% chance at raid specific amount of honors: 480k in the case of Osiris. They contain the most desirable drops in a raid such as the weapon drops. When farming a raid, this is the chest you want to aim for. The typical strategy is to deal the blue chest amount and then moving onto the next raid. Below is a list of strategies on how to effectively and quickly achieve blue chests.
Beginner
These setups are oriented towards beginner players.
Relic Buster 
Relic Buster is the easiest way to achieve a blue chest. Limit Burst

(Consumes all Machine Cell.)
makes it simple to to perform a teamwide charge attack burst. It also supports a wide variety of characters and is very flexible grid wise. Weaker grids and characters may need to press additional buttons to reach the desired damage.

Notes

- Press additional skills as needed.
- Huanglong
support also works. - Selene (Light)
is the best MH for this for it’s strong CA and not needing to press RB1 on turn 2.
Chrysaor
Chrysaor with Harakhte is an easy way to get MC and the entire party to 100% charge. It is a great option for CA setups thanks to Dual Arts

(Can only be used when an auxiliary weapon is equipped.)
allowing for 5 CAs in one turn.

Advanced
These setups are oriented towards players with stronger grids and characters.
Nehan 
Nehan
is the best buffer in light and is core to every auto based burst team. His skill 3 Nirvana
All other Light allies gain Double Strike (1t).
(Inflict Max HP Lowered (Stackable / Can’t be removed) (30% (90% Max)) on target allies.)
can be used to grant teamwide double strike allowing for a very quick and easy blue chest.
Notes
- MC class is flexible.
- Before M3, will need either GTA characters or to also press Nehan’s skill 2 Six-Wolf Tonic
All other Light allies gain Wolf Tonic (3T).
.
- After if you can reach 100% TA via grid and EMPs, can use passive buffers that provide more impactful upgrades.
- Use Chain of Falsehood if not using H.Mugen.
MVP
MVP chests are awarded to the player with the most honors in a raid as well as a possibility for other top scorers. While they have an additional weapon drop chance, it is advised to not aim for these especially as a a beginner due to the time it takes. However, if the raid is slow, it helps to join as higher damage output team so the raid can die.

Full Auto
Players can also choose to full auto their own host. While it is slower than blue chesting, it is an easy way to get another drop chance with minimal effort. The following strategies focus on soloing the raid which is particularly helpful for slow periods. But it is strongly reccomended to call up backup request after securing the blue chest to speed up the clear.
Lumberjack
Lumberjack is one of the safest classes to full auto with and the buffs provided by it also helps weaker grids to reach damage cap. Characters can easily be upgraded to better and strong options.
Notes
- All characters can be replaced by others like Aglovale (Valentine)
, Lucio
, Lily (Holiday)
, Grea (Light)
, or Tikoh
among many others. - Finding a level 250 Lucifer
as support will both make FA safer and faster.
Relic Buster
Relic Buster offers a good balance of attack and defense making it a great option for full auto. Pairing this as well with stronger characters makes for a much faster FA than lumberjack.
Notes
- All characters can be replaced by others like Aglovale (Valentine), Lucio, Lily (Holiday), Grea (Light), or Tikoh among many others.
- Depending on characters Auto-Guard may need to be enabled.
- Finding a level 250 Lucifer as support will both make FA safer and faster.
Manadiver
Zeus can forgo dealing with any of the omens and go all in on offense. Manadiver
is very strong for this thanks to its pairing with Light’s skill supplemental options.

One response to “Osiris”
I think for the Chrysaor build in Blue Chest Setups you probably meant something else since Windhose isn’t in Light. Probably Harakhte as the auxiliary weapon since it has +10% all ally charge bars on ougi? The grid currently makes it look like a Lumi Sword is the auxiliary weapon.
