For easy level 1 formulas to craft, most users suggest, Philosopher's Caches, or Orb Aggregates.
The components for Philosopher's Cache are all farmable, so you can get them yourself by playing zOMG, towns, fishing, and some other games.
Orb Aggregates only require 100 orbs, which you can farm in zOMG.
If you are playing zOMG and are sitting on a pile of unused orbs, then its the best thing.
Both formulas are found in the Bifrost.
Also, you can use these formulas to get yourself to level 3, after that they will no longer grant you xp.
