You carry out the wishes of a mighty beholder and in turn, its interpretation of your appearance has been projected onto you. Such a transformation might entail additional eyes floating around your head or your existing eyes merging into one. You always have the Ray of Enfeeblement spell prepared and can cast it once without a spell slot, and you regain the ability to cast it that way when you finish a Long Rest.
In addition, you have Advantage on all perception checks made to uncover traps or discover hidden objects.
