Blinding Flare

Choose one creature you can see within range. The target must make a CON save, taking 18 (4d8) radiant damage on a failed save, or half as much on a success. On a failed save, it is blinded until the start of your next turn.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
