Using the standard block, ramp and stairs, ROK building materials will consist of sticks, thatch, clay, wood, re-enforced wood, and stone. Thatch, sticks, wood and clay will be widely available and often the first choice in material for beginning level housing. While these materials will offer shelter from poorly equipped enemies, they are easily breached by other players. Stone will offer much greater resistance to basic attacks and will only be damageable with siege tactics. Players will be able to build their homes, towers and castles any way they like, but will need a great deal of space during elder content play in order to hold a large number of production, refining, and collection stations.
Building castles will be a natural occurrence for players who reach elder content gameplay. With the large number of production stations, refining stations, collection stations, chests, torture devices and respawn beds available for the player to build, comes the need to protect a large footprint of space.
