Okay so I think I'm progressing into mid-late game and I have a lot of questions about what I should be doing.

1. I'm currently using Nicki as a Faimon Hell farmer, 100% Auto <1 minute per run. Should I focus on a new farmer and rune her for Cairos as a sub for Konamiya? Was planning Despair+Focus

2. I'm about halfway done with Sigma fusion, should I focus on finishing him or 6 starring my currents?

3. Whats Optimal Veromos rune set-up

Thanks in advance!
