Fighters can throw sand, so why not casters in 5e DnD?
Throw Sand
1st-level conjuration
Casting Time: 1 action
Range: 15 cone
Components: V, S, M (a pinch of sand)
Duration: 1 round
By grinding the sand between your fingers and blowing the sand, you throw a pile of sand at hurricane force winds . All targets in a 15 foot cone must make a Constitution saving throw. On a failed save, that target is blinded until the end of your next turn. The caster gains the ability to disengage as a bonus action.
