Well, since this is crafting thread, let me post my inquiry here.
I was going into the wiki to see what king of skills are required to craft specific equipment, so I want to check this info.
1) If wanting to craft just leather armor, only tailoring is needed
2) If wanting to craft infused leather armor, some mechanics is needed, together with tailoring, but not a lot
3) If wanting to craft any other armor, both high mechanics and tailoring is needed
4) Regenerative vest is only armor component that requires high skill in both biology in electronics, making it most skill expensive piece of the equipment in the game
5) Biohazard vest and carapaces require small skill investment in biology
6) If wanting to craft non-energy weapons, high mechanics skills is required
7) Some weapon attachments or scopes require small skill investment in electronics
8 ) Only weapon attachments that require high skill in electronics are smart modules,
9) Energy weapons require high skill in electronics and small skill investment in mechanics
10) Melee weapons require high mechanics only, or mechanics and electronics if using electroshock
11) Unarmed weapons require also high tailoring as well as all mechanics and electronics for electroshock
