Taxidermist

Preservative Fluids

At 3rd level, you learn the gentle repose spell and can cast it at-will.

Embalmed Companion

At 3rd level, you gain the ability to magically embalm and reanimate the corpses of dead beasts, turning them into your faithful companions. This process can only be enacted on beasts with a CR of 0, and takes 1 hour, at the end of which the corpse becomes an undead creature under your control which is protected from decay. They otherwise possess the statistics they did in life.
  You can have a number of Embalmed Companions equal to your intelligence modifier. On each of your turns, you can use a bonus action to mentally command any creature you made with this spell if the creature is within 60 feet of you (if you control multiple creatures, you can command any or all of them at the same time, issuing the same command to each one). You decide what action the creature will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the creature only defends itself against hostile creatures. Once given an order, the creature continues to follow it until its task is complete.

Restoration

At 7th level you gain the abilty to re-unite the soul of a creature with its body. You learn the raise dead spell, which you can cast as a ritual requiring no material components. Once you have cast the spell in this way, you must finish a long rest before doing so again.

Anthropoid Resources

At 14th level, you can use your Embalmed Companion feature on humanoid corpses, which gain the statistics of a mummy instead of those they possessed in life.
