Armor (leather), rare
Armor of Reprieve (Leather Armor) - This well made leather armor is of exquisite construction. The hides used to make this armor grant the wearer the ability to re-roll any saving throw they like. Once used the PC must finish a long rest before the ability can be used again. This ability can be used as a bonus action after the DM informs the player weather they succeed or failed (PC MUST have an available bonus action).
Otherwise it functions as Leather Armor.
The breastplate and shoulder protectors of this armor are made of leather that has been stiffened by being boiled in oil. The rest of the armor is made of softer and more flexible materials.
