Adding on to my comment, I just found Bottle #6 from a silver chest at the Sundry Oasis. So that means #1 from Galiene (need confirmation), #2 from shop, #3 from Fullblossom Woods (need confirmation), #4 from Magma Mounds, #5 from Dark Woods, and #6 from Sundry Oasis. Also, side note. Found my 3rd Elf Sage from Oasis too. Still looking for the Silks for Belly dancer outfit. Only found 1 and i dont remember where i found it.
Edit: Ah, found 2nd Silk in the Oasis. Now i need 2 more
Edit 2: Bottle #7 is at Fairlily Lake
