Editing Dungeons & Dragons Glossary (section)

=== M ===

;MAD : '''Multiple Ability Dependency''' (4E, 5E) - a class (or Paragon Path, etc.) that relies on more than one Ability Score; seen as a deficiency since this requires splitting points between abilities, and thus lower possible maximum scores.

; megadungeon
: A dungeon large enough to challenge an adventuring party for their entire career, from 1st level to the endgame. The campaigns played by the creators of the hobby (Gygax and Arneson) both featured megadungeons (Castles Blackmoor and Greyhawk), but no true examples were published during the peak of ''D&D'''s popularity. Considered one of the cornerstones of the OSR.

; metaplot
: A larger plot happening in the game world expressed through published adventures, that players may or may not be able to change. Most often used in reference to White Wolf’s ''World of Darkness'' games, but sometimes applied to the ongoing history of D&D campaign worlds like the Forgotten Realms.
