Shell Constructor
Grows a new body from a sample of your own.
Recipe
The constructor is two blocks tall. Place it with a free block above it.
Taking a Sample
Right-click the constructor with an empty hand. It takes a genetic sample and starts building a shell that belongs to you.
The sample costs 20 health, or 40 in hardcore. That is a full health bar, so with no preparation it kills you. Ways around it:
- Eat a golden apple or an enchanted golden apple for absorption first.
- Hold a totem of undying in either hand.
- Have the server enable
warnPlayerInsteadOfKilling, which refuses the sample when you do not have enough health instead of killing you.
If you do die the shell still starts building. Only one shell can grow in a constructor at a time, and it stays there until you sync into it.
Powering It
A shell needs 256000 FE by default (shellConstructorCapacity), and shellConstructionSpeed scales how fast that fills. Any Forge Energy source works: a 
Treadmill touching the constructor, an FE cable, or a generator from another mod.
A comparator against the constructor outputs the build progress. Jade shows the owner and a percentage.
In creative mode with enableInstantShellConstruction turned on the shell finishes instantly.
Colors
Sneak and right-click the constructor with a dye to recolor its trim. Shells built inside take that color in the shell selector, which is handy for telling bodies apart.
Zero Point Shell Constructor
Zero Point Shell Constructor
Upgrade a constructor with a nether star. It needs no power and finishes shells instantly. The sample still costs health.
