The Gauntlet of Infinite Power

Forged by a powerful Human wizard a thousand years ago, The Gauntlet of Infinite Power was made for the purpose of of destroying the evil forces of the land. However, after it nearly fell into the hands of a powerful cult leader attempting to merge the nine hells with the material plane, the Gauntlet was deemed too dangerous to be kept in tact. Its rings were removed and sent all over the known world, Faerun. With its rings removed, the Gauntlet itself was nothing but an old dusty artifact.

The Gauntlet of Infinite Power was ordained with six rings, whenever one of the rings is recovered and reattached to the Gauntlet, it gains powers as follows:
The Ring of Brilliance - Once per long rest, the wearer may automatically succeed any knowledge check of their choosing, regardless of proficiency.
The Ring of Evasion - Once per long rest, the wearer may force an attack roll made against them to automatically fail.
The Ring of Fortitude - Once per long rest, the wearer gains temporary hit points equal to their level, those points disappear at sunrise.
The Ring of Might - Once per long rest, the wearer may automatically roll a critical hit on a melee attack of their choice.
The Ring of Presence - Once per long rest, the wearer may automatically succeed in an Intimidation, Persuasion, or Deception check of their choice.
The Ring of Survival - Once per long rest, the wearer may automatically succeed on an Insight, Survival or Perception check of their choice.

The wear of the Gauntlet of Infinite Power retains the power of each ring, without that ring needing to be attuned. (For example, if you have just the Gauntlet and the Ring of Brilliance, you keep the saving throw ability, and +1 Intelligence without needing to be attuned to the ring)

With the all 6 rings the wearer also gains the following:

+6 to all ability scores, this can raise natural ability scores above 20.

You may cast spells with merely a snap of the fingers, and avoid all material costs for the spell casted.

Notes: Must be attuned by a Spellcaster, Handwear
