Frieren: Beyond Journey's End, Volume 6 (Frieren: Beyond Journey's End #48-57)

The mages begin the second stage of their certification exam: a dangerous expedition into the innermost depths of the ruins of the king’s tomb. This time, there are no teams and it’s every mage for themselves. Whether they want to team up or not, the challenge they will face - their own clones - will push their skills to the limit.
