Skyblinder Staff

You gain a +1 bonus to attack and damage rolls
made with this magic quarterstaff. While holding
it, you gain a +1 bonus to spell attack rolls. If a
flying creature you can see within 30 feet of you
makes an attack roll against you, you can use your
reaction to hold the staff aloft and cause it to flare
with light. The attacker has disadvantage on the
attack roll, and it must succeed on a DC 15
Constitution saving throw or be blinded until the
start of its next turn.
