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.
* Two more header-adjacent values (cols 9–10, not shown below) appear before the target reference — likely a required skill/level and a related cost, but the exact meaning hasn't been traced through the client and isn't asserted here.

This decode is inferred purely from the consistent cross-referencing pattern in the data (the same dat/entry addressing scheme used by missions, NPC shops, etc.) — it hasn't been confirmed against the client's scroll-use code path, so treat the target/material interpretation as strong-but-unverified.

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.
