Myrmidon Nurses have a special Lesser Alchemy of their own. They can brew potions a drop of which will turn mud into something like quickdry cement (which is waterproof), and potions that cause larvae to mature into Workers, Nurses, Drones, Warriors and other types for certain tribes. They also make the Royal Jelly the Queen eats and which is fed to Queen larvae. This is a M/H skill to learn just these or a M/VH skill to learn Myrmidon specific potions plus the rest of Lesser Alchemy.

Pixie Alchemy
