Akhan's Brilliant Lightshow

You conjure a field of dazzling blue lights that fill up a 500 foot cloud. These can take the form of stars, insects, or flowers, or something similar— butterflies are typical. The lights provide dim light to any space they fill. In addition, anyone who sees the lights for the first time each day gains a d4 they can add to any ability check they make within the next 24 hours.

At higher levels. The lights extend an extra 400 feet for every spell level above the third.
