When you reach age 5/creative age, you don't want to have to be going to mine a random ore, you want to be able to automate everything, and for most things this is possible. Quarrying the different planets will get you all of the space ores you will ever need if using rftools quarrys on max range. However nether amethyst only spawns in a single biome in the nether, doesn't come out of void miners, and would be annoying to quarry due to that one biome restriction. I suggest that nether amethyst should either be added to the void miners, could be gated behind the highest tier miner, or it's added a s a mystical agriculture recipe for the late game. This is especially necessary as it's something that currently can't be automated for the ultimate ingots, but it's needed to make the knightslime ingot.

I think this is a great idea, but I will say that there is knightslime essence if that's all that you are using it for

Yea that is true, I would just like to see all of these rarer ores automatable at the later ages, at a certain point it becomes tedious rather than fun to go and get more ores. While I can setup quarrys for these things too, I have already had to do this on all the extraplanets planets to avoid having to manually mine all of them to make the tier 10/electric rocket. Would be good to see mystical agriculture recipes for all of the unique space ores too honestly... but that's a seperate issue. The issue with quarrying everything is it causes a bunch of tick lag on the server as those worlds need to be loaded to be quarried, so after you've setup a few quarries it's a bunch of extra strain on the server and the whole experience becomes a lot worse. Having them come from mystical agriculture crops and only having to grab 4 of each makes that a much more pleasant experience all round
