The Magic Grove is arguably one of the prettiest buildings in our Enchanted Forest! It is also one of the more expensive to build. I would suggest taking a close look at ingredients you will need and planning ahead prior to purchasing the Magic Grove.
The Magical Grove was initially available for purchase at L24 but changed with an update in September of 2016 and is now available at L40.
Check Neighbors for a Large Library. These will drop Knowledge each time, which is much easier and less material intensive than getting it from your own Library or Large Library.
Living Water is crafted in the Laboratory, You will need Firewater and (9) Paper for the "Recipe" item used in the crafting of Living water.
You will need a total of 8 Magic Wands for build requirements, including the 3 used in crafting the Living Water.
Magic Wands require Poles that you can get randomly (and very rarely) from Neighbors Lumber Mills (Any Level); but your best bet is to run your own L3+ Lumber Mill ot Large Lumber Mill for guaranteed Poles each time.
