Farming: Rosetta Stones & Lores

Complete Destiny Odyssey I-X & Shade Impulse Chapters 1-4.
This unlocks Duel Coliseum.

Now enter the Air Ship Course with your most powerful char. (this is the lv 1-30 course)
*you will want 2 Treasure boost cards and +1 hand size card.

Now max out your coins and then get the cards mentioned above.
The Treasure cards your interested in are Wind Stones, Water Stones, and Life Stones. These 3 items convert into Lores for equipment abilities OR Rosetta Stones. (its also a good idea to get 99 Transmogridust for item upgrades, specifically the super ribbon which required 99 of them.)

Only battle when you absolutely have to, buying an item you don't really need is faster then winning a battle, when all your interested in is getting a new hand to find the items you want.

When you get close to 500 coins left, hold of on buying items unless they are they key items you are looking for. Instead wait till a X2 card appears then max out your coins and repeat the process again.

I maxed out my Dusty Elixirs, Transmogridust, Wind stones, obtained about 70 Water Stones, and 45 Life Stones in 109 battles.
(not to mention I got around 15-20 of every other item available through this course)


In my opinion this is probably the fastest and easiest way to get dozens of Rosetta Stones, Lores, and Transmogridusts.
