however, it's not guaranteed to drop, it's purely based on chance, and based off of every1's difficulties getting jewels even when solo'ing, i'd say the chance for it to drop is around 15%, also it seems that raids in which there are multiple bosses have an even lesser chance to drop their own mats, around 5-10%, as it is easier to kill bosses that appear in a multiple-boss raid, as opposed to a single-raid where the boss would be otherwise stronger
