Sword of Spirit
Legend
Interesting. Even though it's a tiny entry with little elaboration, I'm surprised I wasnt familiar with it, because the lack of such rules stood out to me in 1e, 2e, and BECMI.This whole discussion did get me curious, as I thought I remember ability checks being core in 2E.
Sure enough, it’s right there in the glossary at the very beginning of the PHB. The only reference to it, other than the one I initially mentioned about “Ability Checks as Saving Throws” is the proficiency section.
Specifically in the section prior to the introduction of the skills systems, called “Using What You Know” as an alternative to using any skill system in the game. It says that in an instance where the DM cannot assume the PC can simply accomplish something, an ability check can be used to adjudicate success, which is effectively B/X.
That said, I don’t think I can remember playing a 2E without proficiencies, as that was one of the reasons we switched from RC BECMI along with “race and class” character building.
Do you happen to know if this was in the original 1989 2e PHB, or was it something added in the revised version? (I only had the original back in the day.)
