How to unlock the Mischief Mastered achievement in The Sims 4 - Definitive Guide
Socialize - troll teh forums
this grinds it for you with minimal effort, i needed it for the Villain part of the secret agent career and it worked really fast. (I did have Savant unlocked for my sim mind you, so yours may take a little longer)
A Computer is not required for this, but is highly recommended. The Mischief Skill is required for the Secret Agent Career (Villain Branch) and the Criminal Career (both Branches). To increase the Mischief Skill, you need to do devious things: Tease other Sims, play pranks, or, the most efficient, “Troll teh Forums” on the computer.
Your skill with increase faster if you have the “Playful” Moodlet active. It’s recommended that you paint a “Playful Painting” and hang it by the Computer. To create one, you will need a Computer and an Easel. “Watch Funny Videos” at the Computer to gain the Playful Moodlet. Once it’s active, you will have the option to “Paint a Playful Painting”. Once it’s complete, open your Sim’s inventory, hover over the painting, and press to pick it up. Place it on the wall near the Computer.
When you click on the painting, you will have the option to “Turn on Emotional Aura”. This Aura will give you a permanent Playful Moodlet so long as you are close by. Make sure whenever you’re at the Computer, the aura is turned on.
Once you have the Moodlet, fill your queue with “Troll teh Forums” over and over again. Keep doing this and when you reach Level 10 (Max Level), the trophy will unlock.
If you are completing Aspirations for aspiration points, you want to work on Deviance - Chief of Mischief/Public Enemy (in that order) while leveling up this skill.
