This mod adds in a few new bionic skin glands. Balanced with vanilla items in mind.
Shout out to &Aurum on the Rimworld discord server for motivating me to make this
For a quick list (I can't be bothered to write their stats all out) here they are:
Thermalskin gland
Vitalskin gland
Psyskin gland (uncraftable)
Ironskin gland (uncraftable)
All uncraftable glands can be acquired as quest rewards or from traders the same way normal glands can.
