Bit strange for a pure diamond farm given the idea is usually to have a low maintenance world. Log in, collect, log off.
It’s an idea that could potentially work. But only if you’re hyper lvling the blue galaxy which you’re unlikely to get without a hyper lvl’d Arc due to needing enough BPs generated and the age of the GB
35 / (3x2) = 6 shrunk wells
35 / (3x3) = 4 full-size wells
In order for it to pay off it needs to be better then 4-6 wishing wells. (That’s if the only space taken to set it up is by the blue galaxy)
If you stop at Lvl 10 then you’ll never break even on the space taken up (for diamond production). Reason being at that lvl you only get 6 buildings sampled. So in order to break even you’d need a 100% x2 bonus. You don’t get that, you get 32% x2.
By lvl 80 you get 13 buildings and 68% x2. At that rate it might break even, might get profit or might lose diamonds. Because it’s double the amount of wells in that space you need half of them to produce (on a x2) to break even. Given you have to win both flips (well + x2) you could end up getting the x2 on the wrong wells
So really it’s only worth attempting the Blue Galaxy if you can set it up faster then you run out of space to place wells and have the wells to put in that spot. Cause chances are it’ll be worse then wells in the same spot but better then no wells if you have extra unused space
