Corona

You unleash a corona of stellar energy in a 10-foot emanation, which lasts until the end of your next turn. You can Sustain your Corona for up to 1 minute. If your attunement changes, your Corona's attunement effect changes to match. While graviton-attuned, your Corona has the Darkness trait. While photon-attuned, your Corona has the Light trait. Graviton-Attuned Your Corona is darkness that prevents light from penetrating the area. This acts as a Darkness spell with a spell rank equal to half your level. Photon-Attuned Your Corona is solar light that sheds bright light in the area (and dim light for the next 20 feet). While within your Corona's bright light, invisible creatures become Concealed, and creatures already concealed are no longer concealed.
