The Horsetail generates Mana comparable to the Dandelifeon; thus, it requires Gaia Spirits to make. It generates Mana by killing Horses, but there are many variables to the production. First, it generates a very measly amount of Mana comparable to throwing Wood at an Endoflame if the horse is inadequate stat-wise; and the better the stats, the more Mana it has. Second, the coat features are important; the second horse in the last 5 horses with the same coat feature experiences greatly diminished returns until enough horses are killed. And finally, while a Saddle increases Mana generated, it cannot have armor or be a donkey or mule, so you can breed armored Horses next to the flower without any bad effects.
