The notable rewards the RuneScape Wiki lists for Zemouregal & Vorkath, 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. “Not in its drop table” is a reward the Wiki gives no single rate for here, such as a set of pieces.
