Editing Dungeons & Dragons Glossary (section)

=== R ===

; RC
: '''''Rules Cyclopedia''''' - a single-volume version of Menzter's BECMI sets, compiled by Aaron Allston in 1991. See also [[Editions of Dungeons and Dragons]].

; red box
: Usually refers to the first box set in the BECMI series by Frank Metzer; see BECMI for full details. May also refer to the Fourth Edition Beginner's Box set which was released in a nearly identical box. (The ''Stranger Things''-themed Starter Set for the fifth edition also used a very similar box.)

; retro-clone
: A replica (or near-replica) of an out of print version of a game. Originally and most commonly used to refer to clones of ''D&D''. Based on the principle that the rules of a game cannot be copyrighted, only the specific ''expression'' of the rules. Many clones rely on the OGC to allow them to use trademarked terms and specific elements (like the names of spells, monsters, or game terms). Also known as a simulacrum.

; rider
: (4E) A secondary effect of an attack power, often based on a class's secondary ability score. For example, the first-level Paladin power "Bolstering Strike" deals damage based on Charisma (it's main effect), and also grants bonus hit points based on Wisdom (the rider). Derived from the "rider" clause in famous band's contracts, which states what they expect to be provided for them backstage (drinks, beverages etc.) in addition to their payment.
