SPELL MEMORIZATION

Preparing a finite slate of spells in advance — the Vancian tradition where casters memorize specific spells at rest, expending them on cast and returning to the spellbook to re-prepare.

D&D's fire-and-forget system is the source (Baldur's Gate and Pathfinder CRPGs implement it faithfully: choose tomorrow's magic tonight), modern 5e-derived designs soften it into prepared-lists-plus-slots (BG3's casters swap prepared spells at will but spend shared slots), and roguelikes and dungeon crawlers echo the structure in limited-charge scrolls and per-rest abilities. Designers use memorization because it moves magic's decision point before the battle: a sorcerer with every spell available answers each fight reactively, but a wizard who prepared wrong must improvise with what's loaded — so preparation becomes prediction (what will today's dungeon ask?), spell choice becomes portfolio construction (utility slots versus combat slots is a real budget), and the rest cycle becomes the strategic heartbeat that paces the whole adventuring day. The system also creates the wizard's distinctive mastery curve: knowing what to prepare is learned dungeon literacy, and the veteran's prepared list is a forecast built from experience. The friction is real and intended — but interface norms decide whether it reads as strategy or paperwork: spell-list presets, re-preparation defaults, and clear slot arithmetic separate the thoughtful implementations from the spreadsheet ones. Key decisions: preparation granularity (memorize exact spell instances versus prepare a list cast flexibly through slots — the old-school/modern divide, trading harder predictions for gentler bookkeeping), re-preparation cost and availability (rest scarcity is what gives preparation stakes), and information fairness — players can only meaningfully prepare if the game telegraphs what's ahead, through rumors, scouting, or genre convention. Pitfall: preparation without prediction material — when dungeons are unknowable in advance, memorization is blind guessing punished retroactively, and players default to the same safe list forever; the system generates its intended gameplay only when the game feeds the forecast, because a prepared caster is only interesting if preparing well was possible.
