Dampen Presence, Invisibility, and Blindsight

[Heavenfluff]

If a invisible character with the Dampen Presence feat ends their turn in stealth next to a opponent with Blindsight, does their stealth break? While dampen presence lets you use stealth against a foe with blindsight, blindsight renders the concealment from invisibilty normally irrelavent, and you need to end your turn in cover or concealment to maintain stealth.

Invisibility grants concealment so they are still not noticed.

[Trekkie90909]

You get to roll an opposed stealth check (vs their perception).

If you succeed they can't see through the invisibility/other flavor text here. If you fail the blindsight picks you up as normal.

[Gauss]

If you are not using your eyes (ie: using blindsight) then illusions, invisibility, concealment, etc. are not relevant.

Lets assume for a moment you have a creature with Blindsight 30' and normal vision (is not blind).

You have 3 targets:
1) is 20' away and invisible.
2) is 20' away, invisible and has Dampen Presence
3) is 40' away and invisible.

#1 is automatically detected by Blindsight. No roll is required.

#2 may be detected if the perception roll is greater than the stealth roll without the invisibility bonus. (You do not get the invisibility bonus against creatures not using sight to detect you.)

#3 may be detected if the perception roll is greater than the stealth roll with the invisibility bonus.
