Your Builder and Engineer powers become part of a greater whole. The amount of cores you produce every 24 hours is doubled and your storage capacity is no longer limited.
You gain the ability to create Clusters and start with three. Each Cluster possesses its own grid of 127 nodes that behave like Embedded Engineer. You gain a new type of Core, the Interchange, which allows nodes to communicate between Clusters, as well as a new type of Module, the Interface, which allows a Cluster to connect to someone else and grants them the ability to use its powers, you have a fine degree of control over the permission of each Interface. Every 120 hours (5 days) you can chose to generate a new Cluster, increase the number of nodes in an existing Cluster to the next central hexagonal number (169, 217, 271, 331, 397, ...), improve a Cluster to make all Modules and Cores within 10% more powerful (multiplicative), or improve your Modules and Core generation by 20% (additive).
The power also provides you with an embedded VI assistant to which various tasks can be delegated. Network maintenance or reorganization, programming of cores, debugging assistance, etc. The VI has a personality of your choice but it is not truly sapient. This assistant can be provided with computational cores to increase its capabilities though it is not capable of evolving into an AGI unless you create that capability yourself.
As the Clusters are bound to your soul, it is possible for you to dedicate a Cluster to host your consciousness. The ability to project a body is optional but highly recommended as your clusters exist outside of reality and, without an anchor or navigation system, you will find it hard to make your way back to the proper place.
