Beware when dealing with devils! The Abomination Vaults sprawl far beneath the mysterious Gauntlight, and it's time to take weapons, torches, and wits into the deeper dungeons. Here, vile fleshcrafters labor to create armies of monsters for their long-dead leader, and a force of devils still work to maintain order among the feral and fractious monsters. An unlikely ally can reveal the secrets of the Abomination Vaults, but his price is steep and must be paid in blood.Hands of the Devil is a Pathfinder adventure for four 5th-level characters. This adventure continues the Abomination Vaults Adventure Path, a three-part campaign in which the heroes explore a sprawling megadungeon to stop an ancient evil from renewing their monstrous vengeance.
