This page of The Sims 4 guide is dedicated to Charisma - thanks to this skill your Sim will have an easier time communicating with other Sims. Read our tips to learn how to best develop Charisma in The Sims 4.
The easiest way to learn Charisma is by practicing before mirror by the "Practice Speech" option. This skill is very useful when you interact with other Sims. Charismatic Sim tells better jokes, compliments other Sims (on the 3rd level), elegantly apologizes (4th level), flatters (6th level), charmingly introduces itself (8th level).
If you have Charisma at least on level 7 you can ask a friendly Sim to loan you a small amount of money (500 Simoleons) and from level 9 you can ask for a big loan instead (2000 Simoleons). However even the better option will be unlocked once you will reach level 10 what will allow you to negotiate with your boss about a promotion (you need to do it by using a phone). It allows you to improve your job evaluation and receive a financial bonus.
