Zero-Level Characters, Part 6: Advanced D&D 2nd Edition
As mentioned in Part 2 of this series, my knowledge of the D&D editions I grew up on is not actually complete. This is especially true of Advanced D&D 2nd Edition (2e).
There is a now-old jibe about how no one has read the 5th Edition Dungeon Masters Guide (DMG) because most DMs (at that time) were older players who had played prior editions. The idea of “rereading a book you already know” caused issues because of rule changes. This is old news to me as I never read the 2nd Edition DMG when it came out.

Quite a range depending upon vocation. Basic D&D only had two categories: Normal Man (1d4) and Man-at-arms (1d4+3).
