To preface this, I’m bored so this is pretty much a random suggestion for funzies.
As an alternative to RNG, what if they made a tower gauntlet dungeon to get a precursor.
It’d be a pretty straight forward dungeon where you face an increasingly difficult wave of monsters on each floor. Finish a floor, move up a level. (I’m oozing with originality here I know. /sarcasm)
Upon beating the final floor (Say floor 100), your party will receive their choice of a precursor (on a once a month cooldown)
Just a thought.
