Additional feedback unrelated to RNG:
While playing this game, I have a text file open where I've written down a table of the "true costs" of prisms and artifacts (900k/90k/9k/900 for T3 prism, etc). If it isn't clear, that is because prism/artifact costs in the game are currently listed as "cost spent each 'craft'" and "total crafts required", but not the combined total, and I only want to start crafting once I have enough resources saved up to afford it.
It would be good to show both the total true cost required, as well as how close you are to being able to afford the true cost with your current resource stockpile.
