Conditional Loot

Leviathan Mare 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 Mare, the condition 3 Charge Attacks or 6 DMG skills in one turn. Between the two, leaning towards the CA cancel is much better since 6 red skills in a turn will be pretty slow. Thankfully for any CA team 3 CAs is very easy.

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

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: 1,232,496 in the case of Leviathan Mare Omega. 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.

These setups are oriented towards players with stronger grids and characters.

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.
