Maybe make some kind of new droppable resource in a specialised side-quest to that would essentially enable players the ability to reroll the values on their idols via those special resource drops in those quests? Maybe even integrate these side quests starting at the end of time to add more to the area than just doing timelines and monolith farming like a side quest becoming available after completing each segment of 3 echo’s within each area of the MoF?
It is difficult enough rng to obtaining the correct combinations together on one idol as it is when it drops, let alone getting the top-end of large value ranges to show up. Just a thought.
