When found, this mummified monkey's paw has 1d4 + 1 fingers remaining. When you attune to it, the fingers straighten. Each finger represents a charge. While holding the paw, you can use an action to expend 1 of its charges to cast the wish spell from it, but only to achieve some effect other than the basic use of the spell. After the wish is granted, one of the fingers curls. Each time a fingers curls, roll a d4. On a 1, that finger crumbles to dust and is destroyed, permanently reducing the paw's number of charges.

A creature can only use each of the paw's charges once, and the paw recalls how many of its charges a creature has previously spent. If you end your attunement to the paw and subsequently attune to it again, the paw retains the number of charges it had left when your attunement to it ended, straightening or curling its fingers to reflect the number of charges available to you.

Curse. Any wish granted by the paw —with one exception— is interpreted in a way that brings as much misfortune to the user as possible without directly harming them. For example, if a creature wishes for a million gp, one million gold pieces appear. However, rather than magically creating the gold from nothing, marked gold coins are teleported from the vaults and treasuries of nearby banks and noble houses, effectively framing the creature for grand theft and making enemies of those the wish robbed.

Only a wish to undo another wish granted by the paw succeeds without complication or misfortune.
