Housing System
Each player's
farm tent has an allotted space on which the
farm tent's owner can build a house. In order to build a house, players require
a land certificate 10 brahmin hides, which can be bought from an
NPC PC or
received as a quest reward by brutally murdering brahmin. Construction can begin after sufficient amounts of the required resources have been accumulated. There is a variety of different houses; the more elaborate and extravagant, the more expensive.
Once a house is completed, players can furnish the interiors with different appliances, furniture and interior elements such as wallpapers and floorboards.
