The Great Gama's Silver Mace

Origin
Ghulam Muhammad's (1878 - 1960) stage name was The Great Gama. He was awarded the Indian version of the World Heavyweight Championship in 1910. Gama remained undefeated in his entire career spanning more than fifty years and is considered one of the greatest wrestlers of all time. Gama received the silver mace from the Prince of Wales which was symbolic of the one that is carried by the Hindu deity Hanuman. Hanuman represented strength and valor.

Effects
Although the massive silver mace looks opposing it grant whoever picks it up with immense strength. Whenever the user starts to doubt themselves the mace becomes heavier and heavier until it cannot be lifted anymore. As a bonus to this if the artifact is put down due to self doubt the user cannot lift even the most normal of things for the next day.

Collection
Warehouse Agents ran a test to see just how bad the downside was. Agent who was negatively impacted wasn't able to lift anything but their arms for the next day including normal weights, another person, even a pencil or fork.
