You create a reserve of faith between yourself and any other creatures you designate within range. This reserve is represented by 4d8s. While the spell lasts, any creature affected can take a single d8 and add it to a roll of their choice. Once all the d8s are taken, the spell ends.

At higher levels. When you cast this spell using a spell slot of 3rd level or higher, the reserves starts with 2 additional d8s for each slot level above 2nd.
