Dune Ward

When a creature moves within 10 feet of
you for the 1st time in a turn or starts its
turn there, use your reaction to hurl a wave
of desert sand towards it. The creature
must succeed on a Dex save or be blinded
until the end of your next turn. You can
use your reaction a number of times equal
to your proficiency bonus, and regain all
expended uses when you finish a long rest.
