To summon an Urban Legend in The Sims 4, you need to reach Level 7 of the Mischief skill. Then click on a Sim, open the Mischief menu, select More Choices, and click on Summon Urban Myth.
Your Sim will then look into a mirror trying to find the reflection of the urban myth they just summoned.
Nothing happens the first time you summon an urban myth. Your Sim will just have a good laugh.
If you keep summoning urban myths, your Sim will notice something strange in the mirror. They’ll get the Scared buff and begin to wonder if the myth is real.
You should stop summoning Urban Myths after this point if you don’t want your Sim to die. If you use the Summon Urban Myth mischief interaction again, your Sim will realize the myth is real. They’ll hit the bucket.
You can trigger death by starvation, electrocution, overexertion, meteorite, fire, Pufferfish, Cowplant, or drowning. Other potentially deadly activities include drinking Beetle Juice, sniffing a Death Flower bouquet, rock climbing, using the Research Machine, relaxing in the sauna, using a vending machine, opening a Murphy Bed, or making a wish at the Wishing Well.
If you have Seasons, Sims can freeze to death, get heatstroke, or get struck by lightning.
The Sims 4 universe is also full of angry flies, poisonous bugs, pets infected with Rabid Rodent Fever, and revengeful Mother Plants.
Spellcasters can die of Magic Overload. Vampires can burn to a crisp from sun exposure.
Emotional deaths such as Death by Anger, Laughter, and Embarrassment are also interesting options. They just require a lot of work to trigger.
If your Sims live in the countryside, angry rabbits and chickens can attack and kill them.
If your Sims have managed to escape all these dangers, they still can’t escape Old Age. Or maybe they can, if you disable that feature.
