A'koss said:Personally, I'm of the opinion that after a certain point in a character's career - intimidation is just not going to be effective. I find it hard to believe that a 20th level adventurer, who's made his career butchering countless nameless horrors, is going to flinch at anything short of an angry god. The check should be against something like 5x the target's level IMO...
With you on that. Problem is that with good and bad rolls, a high cha character with Skill Focus and an 18 cha a 20th lvl fighter with a 10 Wis is gonna get intimidated by a single digit lvl Bard/Rogue.
(Knowing ENWorld there is someone out there right this second figuring out the math to prove how wrong I am with this

If we could find a way to get lvls or BAB or something involved then it could really help.
