Solar

Solar is the daytime counterpart to Lunar, and it asks for 1 in 50,000 rolls, or 1 in 5,000 when it is daytime. Translated, that is about 50,000 rolls at 1x luck, only 5,000 during the day, and as little as 500 with 10x luck in the right weather. Unique tier, added before the Main Update by ep1k_sol, still obtainable according to the wiki. The in-game text says it was made with sunshine by an unknown being on a bright day.

The picture: a bright sun symbol above the player among hazy yellow clouds, five sword-like yellow beams equally spaced around the torso, and a swirling pool of fire at the feet, with small spinning fire particles. Compared with Lunar, which is its stated opposite, Solar is warmer and busier. The cutscene is a black screen with an ominous noise before the edges glow orange-yellow; the breakthrough version replaces that glow with an orange and yellow star that expands. A crafting recipe starting with a Solar Device is listed too. Solar : Solstice is its mutation.
