The notable rewards the RuneScape Wiki lists for Queen Black Dragon, with the rates its drop tables print. Each rate is the one the Wiki prints, under the table it is in on the boss's Wiki page (normal or hard mode, solo or duo, and so on). "With luck" is the rate the Wiki's own footnote on that drop gives with that tier of luck active. A range (1/5,400–1/441) or any other second figure is explained on the boss's Wiki page.

Royal bolt stabiliser: 5/253 (without luck; 5/230 with tier 3 luck or higher) The table above has every rate the Wiki prints.
