Paracelsus the Alchemist will send you on a dangerous mission to collect special Arcane Parchments from specific Elite bosses around Arlor. These Arcane Parchments can then be combined to create a very rare crafting recipe. Use this recipe to combine a Singe Egg + a new crafting element, Undead Ectoplasm into Nekro the Undead Whelp. Undead Ectoplasm only drops from Elite mobs, so they won't be easy to come by, but then again, bringing dragons back from the dead is no easy task either!
