Shattering Barrage
You create three orbs of jagged broken glass and hurl them at targets within range. You can hurl them at one target or several.
Make a ranged spell attack for each orb. On a hit, the target takes 2d4 slashing damage and the shards of broken glass remain suspended in midair, filling the area they occupy (or 5 feet of the space they occupy if the creature is Large-sized or larger) with shards of suspended broken glass. Whenever a creature enters an area of broken glass for the first time or starts its turn there, it must succeed on a Dexterity saving throw or take 2d4 slashing damage. The shards of broken glass dissolve into harmless wisps of sand and blow away after 1 minute.
You create one additional orb for each slot level above 2nd.
Gabal’s Persistent Shattering Barrage. The shards of broken glass do not dissolve harmlessly and instead fall, turning the area they occupy into difficult terrain .
