You begin a booming retelling of a large-scale battle filled with death and destruction, an ephemeral vignette of the tale appearing around you. You initiate the tale with the crunch of armies clashing, creating a shockwave audible to 300 feet that strikes at a creature you can see within 30 feet of you. Make a ranged spell attack against the target. The target being within 5 feet of you doesn’t impose disadvantage on the attack roll. On a hit, the target takes 3d10 thunder damage. On a miss, the target takes half the damage.   Until the spell ends, you can use an action on each of your subsequent turns to have your vignette reenact the clanging of swords, ferocious battlecries, or screams of the dying, repeating the attack against a creature you can see within 30 feet of you. You can direct the attack at the same target or a different one.
