You give the touched creature an aspect of regularity in its motions and fortunes. An unwilling target must make a WIS save. On a failure, the target doesn’t make d20 checks to determine the results of attack rolls, ability checks, and saves for the duration of the spell. Instead, when it would make a check, its results follow the sequence 1, 20, 2, 19, 3, 18, 4, 17, and so on. A creature affected by this spell can repeat the save at the end of each of its turns, ending the effect on a success. If all results on a d20 are exhausted, the spell also ends.

Since this spell doesn't allow its target to roll a d20, Luck isn’t applicable to the sequence. Advantage and disadvantage do apply and use up the next two consecutive results from the sequence.
