There is a thing called "5e: HARDCORE MODE" which is basically a set of house rules for the D&D 5th edition. I want to ask a couple of questions about this thing, but I hesitate how to tag these questions. There is no specific [5e-hardcore-mode] tag, and just [dnd-5e] is just wrong, because the question is not about 5e rules, it is about these particular house rules.
Which tag is more preferable? Should I create a new one?
