Editing Scrolls (section)

== What a scroll does ==

Every scroll record's trailing columns resolve cleanly to a '''crafting recipe''': a target item (what the scroll produces) plus a list of material items (what it consumes), cross-referenced by the same <code>(dat file, entry index)</code> pairs used everywhere else in <code>NN.dat</code>:

* '''Target''' (cols 11–12) — the item this scroll is "for". For files 38–42 this is always a weapon (dat 16–21: Katana/Sword/Axe/Spear/Bow/Bow Gun); for file 43 it's always a consumable (dat 10 or 34, the Medicine category). The scroll's own name almost always echoes the target directly — e.g. <code>Sc.C.A.2</code> targets the [[Weapons#C.A.2|C.A.2 katana]]; <code>Sc.Antidote</code> targets a Medicine entry; <code>Sc.Elixir</code> targets the rare <code>34.dat</code> "revival" entry and needs four ingredients.
* '''Materials''' (cols 13 onward) — a variable-length list of <code>(category dat, entry, quantity)</code> triples, ending in zero padding. For files 38–42 the category is almost always '''35 (Ore)''', with higher-tier weapon scrolls occasionally also requiring '''36 (Monster Item)''' drops; for file 43 it's consistently '''11 (Food)'''. Higher-tier scrolls (higher buy price) generally need more/rarer materials.
* '''Required level''' (col 9) — the production level needed to use the scroll (see [[#Required level and EXP|below]]). Confirmed in the client.
* '''Crafting EXP''' (col 10) — probably the production EXP one craft gives. The client never reads it, so this is inferred from the data (see [[#Required level and EXP|below]]).

The target and material reading is now '''confirmed against the client''' (rg.exe, traced October 2026; see [[#How crafting works|How crafting works]]): the crafting code reads the target to choose which production skill to check, and reads the seven material slots to find the items to consume.

Because scrolls have no combat stats and no description text, this page skips the per-item infobox pattern used on [[Rings]]/[[Armor]]/[[Weapons]] and lists every scroll in one table instead. Each name is still individually anchored, so it can be linked directly, e.g. <code><nowiki>[[Scrolls#Sc.C.A.2]]</nowiki></code> → [[Scrolls#Sc.C.A.2|Sc.C.A.2]].

The '''icon index''' is one flat value per book/file (616–621) — a generic scroll-book graphic shared by every entry in that file, not a per-item icon; the [[BIN bitmapdata|<code>bitmapdata</code>]] image id is still listed per row for consistency with the other catalogs.
