Challenge Mode offers a new way to experience Miseria and is unlocked after completing the main campaign.
Your objective is to reach Floor 90 in a single, unforgiving run. You cannot return to town or travel back to previous floors. If your party dies, the run ends and all progress made during that attempt is lost.
After completing every two floors, you will be presented with three random upgrades from the passive skill tree. Choose one to strengthen your party and shape your build as you descend.
If none of the options fit your strategy, you can reroll them but every reroll will cost more than the previous one. Sometimes, adapting to what the abyss gives you may be wiser than spending your resources searching for the perfect upgrade.
Every ten floors, you will encounter the Blacksmith. By paying him gold, you can recruit a random new character to join your group.
Deciding when to spend your gold, which upgrades to choose and how to build your party will be essential if you hope to survive all the way to Floor 90.
Challenge Mode is designed as a focused bonus experience for players who enjoyed the campaign and would like to spend a little more time with Miseria. It is not intended to be a completely new game or a full-sized expansion, but rather a more unpredictable and unforgiving way to revisit its characters, progression and combat systems.
Thank you to everyone who has played and supported Miseria. I hope Challenge Mode gives you a good reason to return to the abyss and a few more runs along the way.
Have fun and good luck :)
