AC1 "The Shady Dragon Inn" is replete with errors, partly owing to alternate reference to B/X or BECMI rules, but also involving simple arithmetic. This undermines the supplement's usefulness as a quick source of NPCs, since every stat needs to be double-checked.
Numbers in parentheses mean one of two things: if found in the armor class of the character, they show the adjusted armor class when he or she is wearing a magical protection device. If found in the saving throws of characters who have high Wisdom, they show the adjustment for magical attack.
The Shady Dragon Inn (1983)
AC is not given with adjusted AC in parenthesis in most cases (the only exceptions are in the magic-user section), and saving throws are modified to account for high Wisdom, not given with the adjusted value in parenthesis, (or adjusted for characters with a ring of protection).
