I just do daily bounties of Zariman and Cavia

I farm a week's worth of Zariman Quills if I find the best bounty. I then use the Quills for standing in which I can use to buy Arcanes to then sell them for plat. Same goes for Cavia

If there is not better Bounty then I'll come back after 2 hours/tomorrow and check

Builds are scattered in the video for Mag, Garuda, and Saryn
