Hi there
I am at the position that i must choose if i push my bio-essence at lvl 2 to get fast 3 or better push first all of them to lvl 1
The 30%speed is much better for 50 bio-essence, than the 5%atk and 20%speedfrom lvl 2 from 100
It makes more sense to level them all to 1 first and then take the next step. With mutations you’re better off if you raise everything to the same stage.
