Ruby

A gem of a red hue is all the game says about Ruby, and the Sol's RNG Wiki fills in the rest: a red pulsating triangle with square particles of the same color, plus string-like effects that come off the player. The wiki notes they are reminiscent of the ones Natural has, only inverted. Nothing here is flashy, which suits a Basic aura from before the Main Update.

Its chance is 1 in 350, so about 350 rolls at 1x luck, or roughly 35 at 10x. That makes it a natural early target among Basic auras, rarer than Rage at 128 and Rare at 16 but still within reach of any session.

Crafting is the more distinctive part: the wiki lists a Desire Glove, a Jewelry Potion, a Gemstone Gauntlet and 30 Chromatic : Hyper. Four item types is a short recipe by the standards of this game, which is why people sometimes choose it over waiting for the roll. Its Exalted mutation is Ruby : Brimstone. The creator is ep1k_sol.
