In Roria Conquest, raid dens appear to reset based on the in-game clock, and community guides suggest the dens refresh on the next hour or at midnight local time depending on the den state. A wiki entry also notes raid difficulty is tied to star level and gym badge progression, which affects what you can find after a reset.

How to reset raids

A practical way players describe it is:

  1. Wait until the next full hour, or until midnight for a full daily refresh.
  1. Check the den again after the clock rolls over.
  1. If you’re using a method that forces a refresh, save first so you can retry if the spawn isn’t what you want.

What to expect

  • Higher-star raids require more gym badges before they become available.
  • Some communities describe den refreshes as time-based rather than manual, so simply leaving and re-entering usually is not enough.
  • If a den seems “stuck,” the safest assumption is to wait for the next reset window instead of expecting an instant reroll.

Quick Scoop

The short version: wait for the hourly or midnight reset, then recheck the raid den.

The most specific Roria Conquest source found is the fandom raid-den guide, while other results are broader Pokémon raid discussions rather than game- specific instructions.
