You hold your hand about a foot apart in front of your chest and focus, creating a small ball of bright green flame. You then twist your hands in opposite directions as you pull the ball closer to your chest before reversing the twist and pushing the ball away from yourself quickly with you hands palm out.  the ball archs across the air growing until it reaches the target and explodes.  All creatures in a 30ft sphere must make a Dexterity saving throw taking 8d6 fire damage, from a wyldfyre source, on a failure or half as much on a successful save. For each level above 4th that the spell is cast it deals an additional 1d6 fire damage. Wyldfyre is a powerful source of fire damage twisted by arcane magic to turn the flames a bright green color. Fire damage from a wyldfyre source bypasses ignores resistances to fire damage and treats immunity as resistance for all creatures excluding fiends.
