Ratatam's Glowskin Elixir

When you drink this potion, your skin begins to shed dim light in a 10-foot radius around you. As a bonus action, you can choose to intensify this light-shedding bright light in a 10-foot radius, and dim light for an additional 10 feet—or diminish the intensity again. Additionally, you can take an action to produce a flare of blinding light around you. Each creature within 30 feet of you that can see must succeed on a DC 16 Constitution saving throw or become blinded for 1 minute. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. The effects of this potion last for 8 hours or until you use the flare.
