Okay slightly unrelated but here is my take on the concept of “wear a full set of THIS armor to get a bonus!”:
I really hate Set Bonuses, sure for something like a Hazmat Suit or Space Suit it is kinda required (to give full protection from the Environment), but anything else, no. Armor should not give you more of a random Bonus because you happen to have a “matching” Set, you should definitely be able to mix and match Armors and other Equipables.
And in case of Hazmat and Space Suits, just have a flag if a piece of Armor would protect from an Environment (such as lack of air, or toxic gasses, or radiation), so you can mix and match those Suits too if there is more than one option! Who doesn’t want to be a mix of Astronaut and Cosmonaut! Or an Orc wearing a Lead Bucket along with his Radiation Protection Suit!
