Will-o'-the-wisp

You create a series of flickering ghost lights of approximately torch or lantern size within range, that hover in the air for the duration. The light sheds dim, pale green light in a 20-foot radius. The Will-o'-the-wisp can be used to either light the path for the caster or be sent off on it's own in a different direction to try to distract others. Opponents not already in combat must make a saving throw versus wisdom (with advantage) or be distracted by the lights for up to 1d4 turns.  Opponents already engaged in combat or attacked immediately throw off the spells effects as nothing but funny lights.
