Bio License I Chest Modifications

NeuroBuild Core Socket.
Heart Modification. Armor I License

A core socket is a crystalline chamber-shaped implant that is placed inside your heart, replacing the right and left ventricles. By default, a core socket makes you immune to the heart arrhythmia ailment and allows you to have a core inserted into yourself. Cores are a type of armor that bestows a forcefield and can be found within the armor section, though unlike other armors, cores require bio-modification licensing to use, not armor licensing.

The core socket stops your heart from naturally beating and uses the core’s engine to regulate your heartbeat. Without a functional core in the socket, you are reduced to 0 hit points, can not be stabilized without hospital equipment, and automatically fail all death saving throws. Each core socket comes with a “NeuroBuild Dummy” core if no other core is purchased with the install. A core socket costs 1,000 credits and requires 5 hours of labor to install.

A few companies have attempted to produce core sockets and dummy cores for their own brand, however they have minimal to no benefits, and none of them have been released, let alone approved for sale on the open market as they almost all have serious side effects. The exact makeup of a core socket is a closely guarded NeuroBuild secret.
