The Chalice of Everything Everyone Ever Wanted

The Chalice of Everything Everyone Ever Wanted is an item the Guild searches for after meeting an archaeologist in a tavern who hires them.

This leads them to a nondescript crypt of Tanner's Folly to solve various puzzles and avoid traps to get to this artifact.

When they find it, Dob touches it without knowing what it would do and seems to become split into an evil doppelganger version of himself.

Powers
As implied by its name, the Chalice supposedly has the power to grant someone something that they wanted. Alfred Strangetide remarks that it can have several different powers. It is unclear whether or not the Chalice does indeed have these powers, as the only thing it does is create an evil duplicate of the person who touched it. However, this evil duplicate is unimpressed when Prudence offers to bribe him in exchange, as anything he could want can be granted by the Chalice, implying that it at least has some wish-granting powers.
