Invisible Shake Weight of Strength
Wondrous Item – Rare
“…It’s not what it looks like.”
This ancient training device is imbued with magical energy after years of repeated motioning. When an adventurer clasps the Invisible Shake Weight of Strength in a free hand, they gain advantage on strength checks they perform, decided before the roll. This includes attack rolls if using a strength-based melee weapon that only requires one hand to wield.
The device can be used up to three times per day, any more than that and it’s a bit excessive…just like, go on a run or something, dude. While the Invisible Shake Weight of Strength does not make a lot of noise, the workout is so intense that most users let out an audible grunt when they have finished, which may alert those within hearing range of their position.
