Poked my head in at the code const gem_types = [1, 2, 5]; const gem_probabilities = [0.754, 0.201, 0.045]; const five_star_gem_types = [2, 3, 4, 5] const five_star_probabilities = [0.75, 0.2, 0.04, 0.01]; Kind of odd they excluded three and four, and everything I could find searching online says that it should be `0.05` for a five star, so it doesn't look exactly right to me. EDIT: After more searching, it looks like these are community guesses at numbers, Blizzard has not published official drop rates.
