I won't technically be immune to fear effects, but I am a psychic with max ranks in Concentration and the Moment of Perfect Mind maneuver. So I can take 15 on a Concentration check and use that for my Will save, unless I've used my immediate action/maneuver already. So the -2 penalty really means almost nothing...
And even things with Blindsense/Tremorsense/etc will still be flat-footed if I go invisible with Cloak of Deception, right? I am also taking Distracting Ember and Island of Blades, so flanking shouldn't be a problem. This isn't a solo character, either. So... even though I have Darkstalker down, I guess I'm leaning towards changing it to one of the others.
Why no comment on Able Learner?
