The notable rewards the RuneScape Wiki lists for Gregorovic, 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.

Chance of a drop in any number of kills

Crest of Sliske: 1/256 (normal mode) The table above has every rate the Wiki prints.
1 in 256
256 kills
63.3% chance of at least one Crest of Sliske in 256 Gregorovic kills, at 1 in 256. 50% by 178 kills, 90% by 589 kills.

Every kill is its own roll, so the chance is 1 − (1 − rate)kills: at the rate's own number of kills it is about 63%, not 100%. More in the drop calculator
