Can you summon Naiads, for the Nature/Water mages? I think the most common way to get lots of Astral, ESPECIALLY if you have easy access to Water (i.e. you are under water) and Nature (i.e. the Nat 0 underwater Kelp sites), is to make Clams. You know, Water/Nature items that generate astral pearls.

Also, in single-player you can except to keep globals such as Stellar Focus up for long enough for them to pay back the amount of gems you put in them.
