So just a quick clarification, Enforcer is Demoralize and in the Demoralize check, it says "Using demoralize on the same creature only extends the duration; it does not create a stronger fear condition."
But under the Fear section of Special Abilities, it says "Becoming Even More Fearful: Fear effects are cumulative. A shaken character who is made shaken again becomes Frightened, and a shaken character who is made frightened becomes Panicked instead. A frightened character who is made shaken or frightened becomes Panicked instead."
So which one is it? Can I use Enforcer to cause greater Fear conditions or no?
No, the ability specifically contradicts the fear stacking rule
If you want to outright frighten people then a rogue with the thug archetype is your best bet short of magic.
Ah, I see. So the Demoralize skill alone can never go above the shaken condition, unless otherwise noted in feats and abilities. Thank you for the clarification.
Yup, the general rule is: "Fear effects stack making people more frightened."
The specific rule is: "Demoralise doesn't stack to make people more frightened, it extends the duration instead."
Specific overrules general.
EDIT: I shouldn't really have used quotation marks there since I wan't quoting anything, but whatever. =P
