Another Terrible Magic Item Idea: Chainmail Chain Mail
Looks like a suit of masterfully crafted chainmail. Due to its magical enchantment, it provides great protection from weapon impacts, while maintaining an impressive degree of flexibility for the user. But of course, it’s cursed.
Once you put it on, you gain all the defensive benefits of the armor, but you also have to pay the price. The armor can’t be removed through conventional means, and the user has seven days to produce seven copies of this armor and give them to seven other living people.
The copies created will automatically acquire the same properties, as well as the curse, of the original. If the debt is left unpaid by the end of the deadline, the armor will suck the life from the wearer. If it is completed in full, the curse is lifted and the user now has a badass suit of “regular” magical chainmail.
