Conditional Loot
Yggdrasil Arbos Omega features a new kind of chest drop. The Conditional Chest’s drop rate will increased based on the player’s in the raid being able to meant a specific condition. Conditions can be completed multiple times for multiple stacks. Each stack on the chest indicates a 10% chance for the chest to drop maxing at 100% at 10 stacks.
For Arbos, the condition is to land 6 debuffs in a turn. Calling Beelzebub
will handle 3 of them. For CA setups, there are several characters that can deal debuffs on CA like Catura
or Elea
that can help clear it. Normal attack setups would have to press additional buttons to get there if they want to cancel it.
Completing the condition provides a boost of honors. If you can not blue chest the raid, you can aim for the conditional chest and get a solid amount of honors just from doing that.
Blue Chest Setups

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 a good blue chest chance to speed up the clear.
