Staff of Radiance

This staff of yarrow wood is often bleached white with points of glowing golden warmth embedded in the wood. You have resistance to radiant damage while you hold this staff. The staff has 10 charges. While holding it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC: burning radiance* (4 charges), daylight (2 charges), searing sun* (3 charges), or sunburst (5 charges). You may cast the douse light* or light cantrips without expending a charge. (Spells marked with an asterisk are from Deep Magic.) The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff turns to a cloud of fireflies and is destroyed.
