Walker of pandemonium.

"fall from grace, weary angel."  is the incantation for this spell. for every step you take, spawn blue hellfire in a 3x3 around your person. anything that steps into the fire gains disadvantage on all attack rolls while you gain advantage  on all attack roles and constitution saving throws. you take no damage from the fire, however, for every round that you stand in the fire, you must  roll a wisdom saving throw to make sure you aren't consumed by the evil nature of the flames. if you fail more than twice, you go insane, laughing incestanly and take doubled damage. however, while insane, gain tripled damage.
