Cedar's Dazzling Trickery

Take the handful of ball bearings/marbles and roll them to a selected 5-foot cube within range. Once dispelled, the ball bearings/marbles produce a dazzling display of multicolored fireworks.

Fireworks. The target explodes with a dazzling display of colors. Each creature within 10 feet of the target must succeed on a Constitution saving throw or become blinded until the end of your next turn. Every creature within 5 feet of the target gets 1d4 fire damage.

Smoke. Thick black smoke spreads out from the target in a 20-foot radius, moving around corners. The area of the smoke is heavily obscured. The smoke persists for 1 minute or until a strong wind disperses it.

For every level above 5th, 1d4 fire damage is added. Once level 8 is reached, the area of damage becomes 20 feet instead of 10 feet. At level 8, the fireworks can create designs or taunting messages.
