Swords of Revealing Light

A blockade of spectral swords appears from a point you can see within range, protecting you and your allies from on-coming attackers. Each creature in a 15-foot-radius sphere centered on that point must succeed on a Dexterity saving throw or be incapacitated. Creatures hostile towards you and your allies have a speed of 0 while in the area. Also while in the area a hostile creature can't benefit from being invisible nor it can take the Hide action. After 3 rounds the swords desappear and the spell ends.
