Gonna leave this here for anyone else that was mildly frustrated by not knowing how many base recources you need to refine up to make the elixers, as of update 0.7.0
D tier: 1000 Fe, 800 He, 50 Be, 30 Kr
C tier: 2000 Ag, 1600 O, 100 Be, 60 Kr
B tier: 4000 Au, 3200 C, 200 Be,120 Kr
A tier: 8000 Pt, 7400 N, 400 Be, 240 Kr
S tier: 8000 U, 7400, Ne, 400 Be, 240 Kr
S tier: 16,000U, 14,800 Ne, 800 Be, 480 Kr
For those interested, I wrote out the processes I used to get these numbers
D tier: no refinement needed, 1 to 1 what it says is what you need, only put this here to have the full list
C tier: (X) to (X)+ is a 16 to 8 conversion, math it down to 2 to 1, and the required resources are just doubled, so that comes to
2000 Ag, 1600 O, 100 Be, and 60 Kr, per elixer
B tier: (X) to (X)+ to (X)++ is a 16 to 8 to 4, or 4 to 1 conversion, multiplying it by 4 to get the number of base resources needed comes to
4000 Au, 3200 C, 200 Be, and 120 Kr
A tier: (X) to (X)+ to (X)++ to (X)+++ is a 16 to 8 to 4 to 2, or 8 to 1 conversion, multiplying it by 8 to get the number of base resources needed comes to
8000 Pt, 7400 N, 400 Be, and 240 Kr
S tier: (X)+++ to (X)++++ is a 1 to 1 conversion, which makes the needed recourses the same as A tier, just takes much longer to refine
8000 U, 7400 Ne, 400 Be, 240 Kr
S tier: edited upon finding out my version of the game was bugging, and (X)+++ to (X)++++ is supposed to be a 2 to 1 conversion, updated math doubling the previous numbers goes as follows
16,000 U, 14,800 Ne, 800 Be, and 480 Kr
