The Bracelet of Dynamaxing is a powerful artifact that allows the wearer to bond with creatures, enhancing their size and abilities in battle. Once per long rest, it can transform a creature into a Huge form, doubling its strength and spellcasting for three turns, and healing it upon returning to normal. Additionally, the bracelet can unleash a devastating wave of energy, damaging and potentially knocking down multiple foes in its vicinity.
