Breath Weapon: This creature has a unique version of a draconic breath weapon. Rather than a line or cone, it fires an orb, which hits the target and affects anything within a 50ft radius of it. This weapon is useable once every 1d4-1 rounds (result of 0 meaning it is usable on the next round), and causes 20d6 electric damage, DC 35 reflex save negates.
