  • Electrical Burst (1/Day). The arbiter releases electrical energy in a 10-foot sphere centred on itself. Each creature in that area takes 10 (3d6) lightning damage and must succeed on a DC 11 Constitution saving throw or be paralyzed for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Immediately following such a burst, the arbiter becomes stunned for 24 hours.
