A Greater focus can be built as the centrepiece of the Portal Chamber in a player-owned house. It is the second centrepiece able to be built in the Portal Chamber, the first being the teleport focus, and the third being the Scrying pool.
The centrepiece resembles a marble square with a floating, translucent purple book above it, with a glowing star orbiting it.
Aside from appearance, there is no difference between this and the teleport focus. Thus, it is not recommended to build this unless the player really wants the different design, as marble blocks are expensive to obtain.
