Second Sun

Wondrous item, very rare (requires attunement)

This polished sunstone trinket is carved in the shape of a sun and embedded with glowing rubies. Up to 16 creatures can be attuned to the item at once and maintain attunement while within 5 miles of it. If the maximum number of creatures are attuned to it and another creature attunes to the item, someone who is not holding or carrying the item is randomly selected to lose attunement.

While holding the sunstone, you can use an action to conjure a second sun by holding the trinket in a position relative to the lowest part of your body, typically where your feet touch the ground, and speaking the command word. The sun appears in the sky in a position relative to you matching how you positioned the second sun relative to the lowest part of your body—it will always appear at or above the horizon.

The sun’s light triggers effects that require sunlight or similar light, but the light is only visible to and only affects creatures attuned to the second sun and inanimate objects that attuned creatures are touching. If you are indoors or in an enclosed space where the sky isn’t visible, the sun appears within the space and its light doesn’t extend beyond the space. The sun doesn’t emit heat or any energy other than visible light. The sun remains in the sky for 1 hour but disappears early if you use an action to end the effect or use the item again.
