Stuck at R15

[Mok]

i need e72 gems to reincarnate and unlock researches which will help me get further in the game, but i can't reach that amount, currently stuck at e67, i'm using the lightning forge build and it gives me like 0.3e67 gems when it targets blacksmith and then it just doesn't go up. I have every mercenary upgrade possible at this stage of the game; KYE1, Harlequin, Mercenary Spirit, Lucifer. Is there any way to improve this build or make a new one which will be stronger?
If not i guess i'll just have to wait till 0:00 am so my sun force gives me a sheetload of assistants.

Oh, i'm just dumb, i didn't excavate at all so my mining prodigies and dwarven heritage gives no bonus, just got to e73 in a single spell combo.
