Re: Mass Effect 1 - Paragon not working

Jeong from ExoGeni is a very hard persuasion option. According to the wiki you either need 12 points in charm (the maximum) or 10 points in intimidate.

 Regarding Wrex: The paragon and intimidate options are always available if you do his personal mission first. If you don't do his personal mission, you need 8 charm or intimidate.

In order to be able to spend more points in charm and intimidate, your paragon / renegade values need to be high enough.
