Let's see, a face slot item that is a full face mask (eye is not a body slot but face is).
The highest CL for any one effect should be the CL for the whole item. The attack bonus minimum CL is 9, and everything else listed below has a lower minimum, so I will use CL 9 for the calculations.
- +3 insight to attack rolls should be 11,250gp.
- +5 bonus to Sense Motive just for "assessing an opponent" would be 1,250gp (1/2 a full skill bonus). The rest of the Scouter is flavour text, which you can keep or alter as you see fit.
- Communication with other "combat masks" should probably cost 2,000gp (based off of Ring of Communication).
- Always provides breathable air is 9,000gp.
Limit the following to having only 1 active at a time (Multiple similar abilities, for price reduction.)
- See Invisibility 1/day is 6,480gp.
- Detect (Law/Chaos/Good/Evil/Magic) each usable at will would each cost 16,200gp.
- Identify 1/day is 3,340gp.
Since each ability after the 1st, most expensive one has a stacking cost of x1.5, my tally would place the final price for all of this at 92,810gp.
