7th ring Arcane, Evocation
When the sword appears, you make two melee spell attacks with the blade, each one against a target of your choice within 5 feet of the sword. On a hit, the target takes 3d10 + your spellcasting modifier force damage. Until the spell ends, you can use a bonus action on each of your turns to move the sword up to 30 feet to an unoccupied spot you can see and repeat these attacks against targets within 5 feet of the blade.
