Note – This adventure is a part of the Quests of Doom series. It’s here for those who just want to purchase individual parts of the series, but if you already have Quests of Doom, you already have this adventure.
Deep in the Vale is for beginning characters, with a bias toward fighters.
Player characters should start Deep in the Vale at 1st level with zero experience points. As they complete each encounter, give them the experience points they earned immediately instead of waiting until the adventure is over. Ideally, characters should gain a level or two (and the hit points and other benefits those levels add) before the characters wrap up the adventure.
