A Grand Incursion is a massive catastrophe that occurs in the Forsaken Land.
When it happens, numerous Incursions occur simultaneously across all regions.

Grand Incursions begin at 21:00, after which multiple Incursions are generated.
If you stop cetain Incursion Stages, the Grand Incursion boss corresponding to that stage will appear.

Defeating the boss ends the Grand Incursion, granting contribution rewards and server rewards.

※ All Incursion that occur together with the Grand Incursion will stay active for a limited time.
