PanRi Free Roam - Dark Realm Swallowed Time Trial

The swallowed time trial can be entered after you complete the Sacrificial Altar quest. Start the trial by walking up to the first gate. You will get a notification with any current bonuses you have active, and how long you have to complete it upon starting the time trial. You will also get a debuff placed on you showing how much time you have left. When the time runs out you get teleported back into the caves beneath the Exile's Tavern. The goal is to reach the end and open one chest before the time runs out.

Bonuses
Some monsters drop power shards when killed. Interact with these to get permanent bonuses that take effect on your next run, meaning the scenario gets easier each time you run it. Bonuses stack up to 10 times each and include:
 * Boosts to damage and healing
 * Extra time
 * Reduced damage taken

Rewards
If you reach the final chamber in time you get to pick one of three chests. You can run the scenario multiple times to unlock all 3 chests. After unlocking all 3 quests there is no reason to run the scenario other than for fun.
