Amnistia's Flaming Bond

You attach a gold coated thread to one target per thread (up to two), forming a warm bond with them.

For the duration of the spell, both the target(s) and the caster gain the ability to send a warm feeling across the thread, granting a ward against fear. For 1 minute, the bearer gains Immunity to the frightened effect and advantage on wisdom saving throws.

In addition, if the bearer of the thread dies, both their thread and that of the opposing bearer(s) erupt in flame, dealing 2d8 fire damage to hostile creatures and objects in range.
