So yeah... this has worked for me. I go T1 Cosmic Belt first and T3 Health Thingoes. Then I build all of Dr. Destiny's Dreamstone. I finish off the Belt next, then move on to the Robe and the Book of Eternity (Depending on if I need Health or Power). Finally, I wrap it up with the Atlantean Seal to cap off everything nicely if the game goes on that long.
