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, monthly campaign in which the heroes explore a sprawling megadungeon to stop an ancient evil from renewing her monstrous vengeance. This adventure also includes a close look at the wicked will-o'-wisps, an examination of Golarion's fleshcrafters, and new rules and monsters! Each monthly full-color softcover Pathfinder Adventure Path volume contains an in-depth adventure scenario, stats for several new monsters, and support articles meant to give Game Masters additional material to expand their campaign. Pathfinder Adventure Path volumes use the Open Game License and work with both the Pathfinder RPG and the world's oldest fantasy RPG.
