Infiltration

Mandalorians were masters of survival in the wilderness, so infiltration is second nature. During the Old Republic and the Sith Wars, their ability to infiltrate behind enemy lines was unparalleled. They developed cloaking devices that camouflaged their infiltrators from their enemies easily. While the technology has been lost, the skills they learned to remain unseen have not been.
When necessary, infiltrators abandoned their typical Mandalorian armor to blend into the environment. Oftentimes, Mandalorian Infiltrators were of species and races that could shapeshift and change their appearance in order to protect their clan's interests, though it was not uncommon if other races were infiltrators such as bothans and humans.

Prerequisites: Move Silently Rank 5 or higher, Disguise Rank 5 or higher, Intelligence 15 or higher

Prerequisites are not required if the Mandalorian has the Master Spy prestige class.

+5 to all skills that can hide the infiltrator (hide, move silently, disguise).

Forged Documents are half as likely to be identified (divide opponents check against forgeries by 2).

Special Feat: Hide in Plain Sight

The Mandalorian’s ability to infiltrate behind enemy lines is unparalleled. Once inside heavily secured enemy bases or hostile areas the infiltrator remains undetected for 30 minutes (3 turns if the area is an active combat encounter).

After 30 minutes (3 turns), the infiltrator must roll one of the skills they used to infiltrate the area vs DC 10. Every time the check succeeds, and the infiltrator remains in the area, the DC increases by 5 until the check fails, or the infiltrator leaves the area.

If the infiltrator is detected, they may roll an Escape Artist check as if they were rank 5. If it succeeds, the infiltrator escapes the area before the alarm is sounded.

The Hide in Plain Sight feat cannot be used for the same high-security area twice.
