Diminish Senses

This spell is cast by placing the strips around both the eyes and ears of the target creature and speaking a word of power. The affected creature must make a Constitution saving throw which it can choose to fail. Upon a failure, the affected creature is both blinded or deafened to all sights and sounds outside of radius of 10 feet directly surrounding it for 8 hours or until the word of power is spoken again. At the end of each of its turns, the target can choose to make a Constitution saving throw. On a success, the spell ends.
