Apparently I purchased the book of many things but the armor description is missing any benefit. It has charges that you can expend but what those charges do is never stated.The outside surface and internal joints of this armor whir with interlocking gears, drawing on the orderly magic of the plane of Mechanus.
The armor has 4 charges. If you make a d20 roll while wearing this armor, you can expend 1 charge to change the number rolled to a 10. The armor regains 1d4 expended charges daily at dawn.
