Boreal Valley Soul Spear

Soul Spear. A beam of crackling soul energy bursts out from your focus in a 5-foot-wide, 60-foot-long line. Each creature in the line must make a Constitution saving throw. On a failed save, a creature takes 6d8 force damage and is blinded until your next turn. On a successful save, it takes half as much damage and isn't blinded by this spell. Undead and oozes have disadvantage on this saving throw. This version of Soul Arrow is not negated by Shield.
