Initiation Time: 1 action
Range: Self (30-foot line)
Duration: Concentration, up to 1 minute
A beam of roaring flame flashes from your hand in a 5-foot-wide, 30-foot-long line. Each creature in the line must make a Dexterity saving throw. On a failed save, a creature takes 4d8 fire damage and is blinded until the end of its next turn. On a successful save, it takes half as much damage and is not blinded.
You can create a new line of flame as your action on any turn until the form ends.
For the duration, a mote of shining fire burns in your hand. It sheds bright light in a 30-foot radius and dim light for an additional 30 feet.
At Higher Levels. When you initiate this form at a higher level, the damage increases by 1d8 for each level above 4th.
