Crimson Realm is a recurring event that occurs in Combat Sectors. When a Combat Sector is the target of the Crimson Realm effect, unique Starless-related events will occur and additional items may drop.

Effects

During Crimson Realm, all Starless gain a passive 50% bonus to their HP. Additionally, they will all benefit from weather conditions, granting them the ability to deal extra damage.

A unique boss enemy, Tyrant Dryverus, can spawn with a trial where you have four minutes to defeat it. If you cannot defeat it in time, you will get rewards based on how much damage was dealt to it.

The timer begins the moment somebody interacts with the enemy, so be sure to engage it while everyone is nearby.

Burst Change

Clearing Trials has a chance to cause a second Trial to occur, spawning a Starless boss with a relatively short timer. Defeating it triggers a Burst Change stack, forcing the next PSE Burst to occur to either become a Forte Burst or a PSE Burst Encore.

Clearing multiple Trials can trigger multiple stacks of Burst Change, and you can have both effects at once.
