The marble portal nexus can be built in the Portal Nexus space of the Portal Nexus in a player-owned house. It requires 72 Construction to build and when built, it gives 2,000 experience. The player must have a hammer and a saw in their inventory to build it, meaning it could theoretically be built at 64 construction through the use of a crystal saw and a +5 spicy stew boost. However, the earliest a Portal Nexus room can be built is at 67 Construction using only the +5 boost from spicy stew, as the crystal saw does not affect the levels required to construct rooms.
The marble portal nexus can be directed up to four locations of a player's choosing; to do so, a payment of 1,000 times the required runes for casting the teleport spell is required for each directed teleportation (some teleport spells cannot be directed). Additional information about adding and customising the portal nexus can be found here.
