Outlaws don't have a village affiliation, but are part of Syndicate. The Syndicate faction is constantly at war with all villages.
You can leave your current village after you've reached Chuunin rank. Go to Preferences to leave your village.
Note that when you leave a village, you lose:
Outlaws gain abilities that normal villagers do not have. These are:
The ability to steal ryo from other players.
The outlaw version of the tavern. Unlike village taverns, Rumors is available from anywhere on the map.
You can scavenge from the ground. Unlike ramen, scavenging costs no ryo and is limitless, making it a fast and effective way to recover small percentages of HP.
Replaces your house while you are an outlaw. Camping gives less regeneration than houses do, but it's free. You can also camp anywhere on the map, as long as it's not in a village.
Outlaws lose certain village comforts:
To join a new village as an outlaw, you must first travel to the village you plan on joining. Once there, you can do diplomacy in that village.
The amount of diplomacy needed to join a village is 10 x your waking regeneration as an outlaw. Once you have enough, the “Join Village” option will appear.
Your regeneration will be cut in half the first day after joining a village, and will be at 60% the next three days. This cut applies to all regeneration, including any temporary boosts bought through the Black Market. Your regeneration will be reset to 50% regardless of how many times you leave and rejoin a village; the timer will not “add on,” but rather reset.
