Grafting
Breach's flesh-crafting: Graftblood is the resource, and a Fleshgraft's level sets how much of it you can hold.
Partly unreleased. The Graftblood storage curve and the crafting bases below are in the game files; the grafts themselves — which arm, which skill, which stats — are declared in the data schema but ship no rows yet, so there is nothing to list for them.
Crafting bases
The item bases the mechanic works on — six rings and a mail, named for the flesh they are grown from.
