Enchanted Dandelion

Enchanted Dandelions are crafted from 160 Dandelions. They are not part of any Collection, and have no requirement to unlock the recipe. Their only use is to upgrade the Flower Minion. It's the most valuable enchanted item with the exception of items with enchanted block forms (such as enchanted diamond blocks). It goes for to  on the auction house per stack because there is no easy way to farm them. The easiest way is to make a farm is to use bonemeal, a water source, and a cobblestone minion to make water flow down to grass after you bonemeal it, get the dandelions, drop them into hoppers and the water will be gone.

It is also possible to buy up to 4 Enchanted Dandelions worth of Dandelions from the Builder each day. It takes 250 days to get all Flower Minion upgrades (Till Tier X) if you buy all 640 Dandelions every day from the Builder.
