Tales from Candlekeep: Tomb of Annihilation will allow you to choose your desired level of difficulty before venturing each quest: Normal, Hard or Horrific!!
The harder the difficulty you select, the more experience points and crafting materials you'll earn.
Furthermore, by playing a harder difficulty, you also increase your chances of looting highly scarce items.
Do you think you have what it takes to conquer the Horrific mode of Tales from Candlekeep?
