Drygmy

From the Worn Notebook which can be created with the Ars Nouveau mod:

   Drygmys are often found following and tending to animals around it. They can be found anywhere, though somewhat rarely. Drygmys can be given a home in the world, and will produce items from nearby monsters and animals as if they were slain, without harming them. A wild drygmy may be befriended by throwing a Wilden Horn near it!

   A Drygmy can also produce experience gems!

   Summoning
   To summon a Drygmy, use a Drygmy Charm [received by giving a Drygmy a Wilden Horn] on a block of Mossy Cobblestone. After a short time, the cobblestone will transform into a Drygmy Henge and summon your Drygmy! To summon additional Drygmys, use more charms on the Henge. Casting dispel or killing the Drygmy will return your charm.

   Happiness
   A Drygmy considers its home to be 10 blocks in every direction from its home. The drygmy will use this area to produce items from any entities nearby. Your Drygmy's efficiency is dependent on its happiness. This may be increase for each entity nearby, with a b onus for each unique type in its home.

   Production
   Each Drygmy working around a henge contributes progress. Once maximum progress has been reached, the henge will generate items and experience gems and deposit them into nearby inventories. Each time this occurs, the henge will require Source to recharge. The number of drops and experience gems is equal to the Drygmy happiness and experience value of the entities. To get started, place a chest and jar of Source next to the Henge.
