Go to the Bifrost. Buy the formula for the Philosopher's Cache. Collect lots of classic Gaia Game items, preferably by playing the games yourself to save money, and craft the Cache.
Opening the basic Philosopher's Cache will get you a random one of
these, and then opening that will get you your choice of
these.
[
edit] Oh, by the way. If you're Level-1 your success rate for crafting the Cache will be gawdawful, so level up with Alchemy Starter Kits, Orb Aggregates and/or Giant Rainbow Lollipops first.
