If you use the reanimation ritual on a dead sim (their grave) and then use the potent cure elxir, do they stay alive or do they just end up dieing again?
If you have the Reanimation Ritual, you don't need Potent Cure Elixir, as you'll also have Sunlight Charm which works to cure a Zombie the same as the elixir would. I took one of my sims to the graveyard and raised all the 'named' dead, then cured them via sunlight charm. If it says "Remains", it won't work. You need graves with the Sim's name on it. You could also just 'manage the dead' in the mausoleum, and then put down whichever dead Sims graves you want to raise/cure.
