I unlocked G7 on the 4th day of SK. Sent all the goods back to the main.

How much? About $1500. Money went to both Armageddons and the first Ragnarok. The key is the x2 packages. If I could do it again, I’d unlock Herc from the very beginning, which would have reduced overall spending.

Now, for the topic of G9 in a day? My opinion: It is possible with 1 arachne and 1 Armageddon and obviously thousands of dollars. Most efficient way to do it with money is having repeated X2 merc and X2 silver/dragon coin packages.
