Blinding Bubble Beam

You cause a cloud of blinding Bubbles to appear momentarily on one creature you can see within range. The target must succeed on a Dexterity saving throw, or it is blinded and moves 5 feet in a random direction if it can move and its speed is at least 5 feet. Roll a d4 for the direction: 1, north; 2, south; 3, east; or 4, west. This movement doesn’t provoke opportunity attacks, and if the direction rolled is blocked, the target doesn’t move but drops whatever it holds in his hands

The spell’s targets increases by 1 5th level (2), 11th level (3), and 17th level (4).
