Translated Ancient Tome
The manufacturing of a hay golem is not so complex, save for the creation of the most important part: the head. The process requires a precise set of ingredients, such that any exclusion or imitation of a crucial item can lead to disastrous results. When combined with care, the resulting head can simply be fitted into the frame of the hay golem with no need for spells or further transmutation.
For the husk, you must locate a fitting carved pumpkin. Such can often by found in Estates teeming with the undead. While this place will feel somewhat foreboding, there is no better place to harvest this item.
Next, seek out a supplemental shapely vegetation. The best bet is a dank and moist fungus filled region.
Thirdly on the list are stringy vines. The best vines I have found are located on the moon of Luclin in the mad mage's domain. This is why stealth is of the utmost importance.
Next, there is a need for several fragments of the unliving: The claw of an ancient dragon, long dead. Tattooed skin peeled from a zombie - I imagine there are many bloated sailors that would not miss a scrap of their flesh. Tears of those spirits that are long forgotten.
The final elements are the most important, and oddly enough, the most difficult to find. The basking glow of an orange flame, a living essence of a dancing mote of light. These wisps are typicallly found in swamplands. Also, the boiling liquid from the Mistress' laboratory.
Lastly, the reanimation formula. Unfortunately, in all my travels I was never able to find the source of this substance and all my attempts to duplicate it have been for naught. I have often debated whether the extra efforts required for this endeavor are worth my time. Since the first time I laid eyes upon a hay golem, I knew the knowledge of their creation would be mine ... someday.
