Every day is a grave new adventure with the Sims 4 Life & Death expansion pack! This is especially true for Sims who hone their thanatology skill. Everything you need to know about it is included in this post – enjoy!
What is Thanatology?
Thanatology is the study of death and any related events. This includes the process of grieving before and after a loved one’s death as well as end of life care. In the Sims 4 Life & Death, the thanatology skill is added alongside new forms of grief, heartfelt funerals and playable ghosts. Together they provide new gameplay that combines the addition of the afterlife and the curiosity of the living about it.

Once your sim has at least level one of the thanatology skill, there will be an option when selecting bookcases to “Look Up Historical Deaths”. Your sim’s skill will increase as they carry out this activity.
5. Complete Thanatology labelled Social Interactions
Have your sim complete any social interactions marked by the purple Thanatology skill icon to increase their knowledge of the immortal world.
6. Do Voodoo
Use a computer to purchase a Voodoo Doll under the “Order” category. It will cost your sim 850 simoleons. If you need to cheat for more simoleons in the household, then I recommend checking out this money cheats post (includes kaching, motherlode and more).
Voodoo dolls will be added to your sim’s inventory, then all you need to do is click on them to perform voodoo to increase your sim’s thanatology skill!

7. Sit in on Skill Class (requires the Sims 4 Discover University)
Select the “Sit in on Skill Class” option under the Business category in your Sim’s phone. It will cost 250 simoleons and your sim will disappear into a rabbit hole for a few hours to increase their thanatology skill.

8. Use Research Machine (requires the Sims 4 Discover University)
Research machines can be found in the university commons, at the Britechester library or can be bought from buy mode (they are very expensive to buy!). Your sim can research thanatology using this machine to increase their skill.
