I don’t see many uses for downtime days. Would you spend them for a benefit?
Restful
Sometimes you just got to relax. If you spend one complete day resting with no major physical activity such as fighting, no skill checks, nor casting any spells you gain a +1 bonus to checks, skills, and saves for 1 day or until you are reduced to zero hit points. Up to five other creatures can vacation with you and gain the benefit, but they must also do no activities as well.
Thoughts? Is this a given? Is this too OP? Is it something you already do without a feat?
