Blaze of Devils

To cast this spell, you must have the skull lit, with the dust sprinkled in the flames before you cast this spell. If you cast it before the skull is lit and the dust sprinkled, the components will explode, dealing 50 damage to you and setting all your possessions on fire. Once cast, a swirling wall of flames engulfs all creatures in a 60 ft circle, dealing 10d10 damage per turn to all engulfed creatures. This includes your party members, but you remain unharmed. In addition, devil-like shadows will, once per turn,  spring out and attack a random creature in the circle. To decide which creature is attacked, make a Dexterity(Stealth) check for all creatures, including yourself. the creature with the lowest score is dealt an additional 4d12 damage and becomes frightened of you, if it does not die. all creatures within the circle have disadvantage on attack rolls against you and your party memebers, but are so frightened that they hit with reckless ferocity, doing an extra 20 damage against your party members.
