According to the DoomRL Wiki, Baron armor is the "Most mundane armor." It is arguably weaker than a red armor with a power mod. It gives off a build and vibe similar to the Gothic Armor, which is even more unique from its Set element. So I was thinking that the Baron Armor could be adjusted to make it more unique. I assume that the "Baron" namesake refers to the Barons of Hell. Barons are known to be immune to acid damage. Also, I believe they are not wearing boots. So, my idea was to give the Baron Armor unique the element of immunity to floor acid.
I know, Barons are hellspawn, and that's what likely gives them immunity. But this would make the armors more balanced and unique. And it would create a difference between Baron Armor and Gothic Armor.
Of course, Baron Armor may become an exotic, or other things may change. This is just a thought on enhancing the items of the game, not particularly a request.
