Armor of Magical Strength

Source: Tasha's Cauldron of Everything p. 20

Prerequisite: A suit of armor (requires attunement)

This armor has 6 charges. The wearer can expend the armor's charges in the following ways:

• When the wearer makes a Strength check or a Strength saving throw, it can expend 1 charge to add a bonus to the roll equal to its Intelligence modifier.
• If the creature would be knocked prone, it can use its reaction to expend 1 charge to avoid being knocked prone.

The armor regains 1d6 expended charges daily at dawn.
