*You can go to prison if you commit indiscriminate murder, theft or assault... AND there is evidence to prove your guilt. (The court decides how long) Or you can try for a prison break!
*You can build your own house. Also villages.

*You can take a carriage to your questing/hunting location and jump off whenever you want.
*Horses can wear equipment and you can use a variety of skills on horseback. (Your horse can die)
*You can build your own ship.
*The under/over achiever system: In ArcheAge, you can complete a quest even if you haven’t fulfilled all of its requirements. There are times when you no longer wish to complete all the goals of a quest, but are reluctant to abandon the work you've already done.
*In ArcheAge, by combining 3 abilities out of 10, you can create your own class. By free ability combination, you cannot only make the basic MMORPG classes such as Warrior, Wizard, Healer, but also unique classes by combining abilities on your own free will.

/cast sheild *sheild spell unavailable*
/csat shield *csat: unknown command*
*[Avatar of Set] beheads [Peasant]*
