Mechanical Skill

[NickytheRabbit]

First post here! My question is about the mechanical skill. Is there a place to see the different kinds of upgrades and what items you can upgrade with every expansions as well? It'd be very helpful for me with some challenges i want to do. I like to plan things out, so this would be amazing if I could use this as reference. Thanks in advance.

Do you mean the handiness skill - where you upgrade and repair broken items?
