I'm stuck in a sort of if/then loop when it comes to this feat.
Dampen Presence says "You may use the Stealth skill to hide from any creature attempting to perceive you using blindsight or blindsense, even if you are clearly in that creature’s perceptual field."
But then it says "This feat does not confer any advantages against other forms of perception, such as scent, vision, or tremorsense."
And then we have creatures like the Banshee, with the "hear heartbeat" ability, which says "banshee can sense the beating hearts of living creatures within 60 feet, as if it had the blindsight ability."
Does this mean we should view the banshee as having blindsight for the feat, or should we think of "Hear Heartbeat" as an "other form of perception?" I'm inclined to think the entries for monsters with such abilities reference blindsight to avoid taking up space more than anything else.
