You should find an option that says Summon Sim (or something like that... TBH, I haven't play TS3 for a little while. I've been on TS4). Click on that and you should see many options. Look for one of them that says Grim Reaper. Click on that (obviously). Wait a little bit, and you'll hear his music.
The Grimophone The old-school-styled item has an option to Summon the Grim Reaper, which can be used to instantly call Grim to your lot. He will hang around outside for a while, and you'll need to go and speak to him to invite him inside. This action has a cooldown of approximately two Sim days.
Once you add the grim reaper to your family/lot. Use "traits. remove_trait IsGrimReaper" to deactivate the reaper features. This will allow you to do normal interactions like woohoo, try for baby, be invited to places and more.
Open up the cheat command. type in traits. remove trait. is grim reaper. so select the person you want to be the new grim reaper. so you will want to open up the cheats command. type in trait. equip underscore trait is grim reaper. this will give the selected sim the grim reaper trait.
Give a friendly introduction and tell him a funny story or two. The Grim Reaper will eventually remove all queued interactions and disappear. As soon as he leaves, call him up on your phone and go to your computer to chat with him. After a few ingame hours of computer chatting, my achievement popped.
As I strategized, I idly scrolled through Morgan's Relationship panel. Of course the Grim Reaper was there, because Morgan had seen death several times. I clicked on the Grim Reaper's icon and found that in The Sims 4, you can not only text and call the Grim Reaper directly, but also invite him for a sleepover.
The Grim Reaper can be pleaded with as in Livin' Large; however, the chance of success is directly linked to the relationship score of the pleader to the deceased: if the total of the daily and lifetime relationship is below 25, the plea is guaranteed to fail.
There are a few scenarios in which Sims cannot plead with the Grim Reaper. If the death is from old age, the plea interaction will be unavailable. If a Sim is eaten by a Cowplant, it will immediately spit out a gravestone and the Grim Reaper will not appear.
In ``The Sims'' series, particularly in ``The Sims 4,'' you cannot have a baby with the Grim Reaper.
All you need to do is keep pushing up that romance meter until the option appears. There are no cheats required for this, but sometimes you need to repeat the selection two or three times before it happens. The option to woohoo with Grim is available for everyone, as it is base game compatible.
