Late league start strategy; pre-ghostwrithe build?

Hey y'all,

I will return from family vacation Saturday and will have about 24h at my disposal before work and family life get the better of me again.

I want to transition into Foulborn ghostwrithe life stacking EB Inquisitor. Seeing that even the 5link is currently at 3 div and I want to transition asap into this build, I was wondering what the best way to get about 5 divs as early into maps as possible is (ideally before full atlas) would be.

I think archmage as a transition build is more my cup of tea than KF totems. How much faster would the latter be?
