If enemies fail to enter combat and block quest progress, try the following steps to resolve the issue.
- Log out and log back into the game to reset the enemy's state.
- Open the Paimon Menu.
- Select the Exit icon.
- Choose Log Out and then log back in.
- Teleport to a waypoint far from the quest area and then return to reset the encounter.
- Close and restart the game client completely for a full reset.
- Return to Single-Player Mode if you are in a Co-Op session, as some quests can experience issues in this mode.
