It is absolutely a net zero! (and yeah I give players the mercy of that part breaking instead of the actual core) - This (ostensibly gag part) is one of a handful of Fabled parts that are based off the three campaigns I ran ((I'm planning on breaking them out into their own category eventually)) the dual core in particular was built as a result of a hilariously failed operation by a PC trying to make their own Fabled part with an inept science crew. He'd joked about wanting to make a dual core to scam people earlier in the campaign and so his vision was later realized ((an immortalized in print))
