Bands of Fenrose

"These platinum bands come in pairs and are normally used in the casting of Warding Bond; but when two individuals use the same bands enough and a strong emotional connection is forged, they begin to hold magical properties of their own."

While wearing these bands, you can take ten minutes to meditate and sense the direction of the other band so long as it is on the same plane of existence.

You can use a Bonus Action to form a link to the creature wearing the other band; from then on, whenever that creature suffers damage, they only suffer half of that damage, and you take the rest. This effect lasts for one hour, until you end it as a Bonus Action, you or the other creature removes their band, or you are more than 60 feet from each other. Once you have activated your band, you cannot do so again until the next dawn.

Strength in Friendship. These bands were imbued with magic power from repeated used of the Warding Bond spell between two individuals with a strong connection. You can continue to use these bands as the material components for the Warding Bond spell, potentially increasing the power of the bands further.
