Rootweaver's Bond

The Rootweaver, Koda, has forged an empowering bond among the chosen of the wind. Once per day, you can all choose to give up your reaction on a turn, to activate the magical bond among yourselves for 10 minutes. While any bonded creature is within 30 feet of another, the creature can roll a 1d4 and add the number rolled to an attack roll, an ability check, or a saving throw it makes. Each creature can add the 1d4 no more than once per turn.
