I did what the DMG said
“Use common sense to determine whether more than one of a given kind of magic item can be worn”
You can disagree with my conclusion if you want to, but for me one of each, two rings is the common sense result.
not to me, that is you making an exception because you want to, I do not want to make one

… this is basically the slots you asked for with permission to overrule them.
First, then why are you asking for slots when they change nothing… Second, they will not get that exception from me
so what, I do not need one and you can use a different sheet that does if you consider it one
I do not see the problems you are bringing up.
