It asks which spells must be in the game for it to be D&D and then it lists all Wizard and Cleric spells, and you can choose which ones must be in the game.
I selected 'NONE OF THE ABOVE' for all of them and left this reason:
"No spell has to be in the game to make it D&D."
For the final comment I left this note:
"The idea that some spell or other 'has' to be in the game for it to be D&D is a ridiculous proposition that panders to players who favor nostalgia instead of design refinement."
I hate the idea that a particular spell has to be in D&D, otherwise it's not D&D anymore This is the kind of thinking that panders to old-school players but kills progress and refinement.
Heroes Against Darkness is guaranteed not to contain any spells that must be in D&D:
