Complete rules
Up to six willing creatures within 30 feet enter Resonant Flow for 1 minute. Each gains one d6 resonance die that can be added to an attack roll, ability check, or saving throw after rolling but before the outcome is known. Once during the duration, each affected creature may also move up to 10 feet as a reaction when another affected creature succeeds on a d20 roll. A caster with a 4th-level slot succeeds automatically; otherwise make a DC 14 Arcana check. The scroll is destroyed after two failures or immediately on a natural 1.
