That's brilliant. Close your eyes and you negate +40 stealth. Rules legal too!I do this every time I read a thread when Invisibility is brought up, but I'd just like to say that when I GM I ignore almost everything about invisibility in the rule books and use the rules for the blinded condition as my base to govern perception checks against invisible creatures. The perception DC to become aware of them is +4, and I run it that pinpointing still requires beating the DC by 20 (so a difficult but possible +24). This makes it a bit harder than it was in 3.5 using Listen Vs move silently, but not as insanely impossible as it is in PF.
It's an example of how mangled these rules became in the transfer from 3.5 that it's now much easier to notice the presence of another creature while blinded than it is to notice a creature that is invisible.
You didn't need those eyes to see, anyway.
