When doing the new Unforgiving Dead gauntlet, there will be more enemies in each battle than intended. They are also different ranks from one another. My max-leveled wizard fought mobs that are Rank 7, Rank 12, and Rank 18. There would also be too many mobs, for example the first battle had 7 enemies, and once you progress you can fight the remaining 3.
This makes the secret boss virtually impossible, as he has a cheat that Mana Burns the player team. This would be fine, but since there are three bosses (at least for me, idk if the number of bugged enemies is consistent) then you lose more pips than you can gain. This makes it impossible to gain the required amount of pips to banish the boss without help from spells like Empowerment or Donate Pips.
