Inscription

A scribe writes the scroll of a spell with a pen and ink, on a blank scroll, from the reagents of the spell. It is the last craft: the rules are the ones of every craft (see Carpentry): the chance, the failures that lose materials, a pen that wears out, and Make last. What is new is that a recipe asks for a spell and for mana, as a cast does. The scrolls made are the ones a mage casts from or writes into a book.

How to write a scroll

Carry a pen and ink, blank scrolls and the reagents in your backpack, and a spellbook that holds the spell (worn, or in the backpack but not in a bag inside it).
Double click the pen and ink. The crafting gump of inscription opens, with a group for each circle, First to Eighth.
Press the button before a recipe, or open its page, which tells the reagents, the Inscription window, the mana and your chance.

A recipe is refused, before anything is spent, with the classic text:

Text	When
You don’t have that spell!	no book you carry holds the spell
You don’t have the components needed to make that.	a reagent or the blank scroll is missing
Insufficient mana for this spell.	you have less mana than the circle costs
You don’t have the required skills to attempt this item.	Inscription is below the least of the recipe

All of it is checked when you start and again at the second stroke, so a book given away or mana spent in between refuses the second stroke and takes nothing.

What it takes

Each scroll takes the reagents of its spell, one blank scroll and the mana of its circle. The mana is paid once, by a success only: the scroll is made, the reagents and the blank scroll go with it, and so does the mana. A failure (“You fail to inscribe the scroll, and the scroll is ruined.”) takes no mana and ruins one unit of every resource, the blank scroll too, which is not the half of the materials the other crafts lose. A success says “You inscribe the spell and put the scroll in your backpack”; when the backpack is full the scroll lies at your feet and only that is said. A scroll is never exceptional nor marked.

Circle	Mana	Inscription window
First	4	0 to 40.1
Second	6	6.1 to 50.1
Third	9	16.1 to 60.1
Fourth	11	26.1 to 70.1
Fifth	14	36.1 to 80.1
Sixth	20	46.1 to 90.1
Seventh	40	66.1 to 110.1
Eighth	50	76.1 to 120.1

The windows are those of the classic data file the engine’s rule was built for: the chance is one in two at the least of the window and sure at its end, as in every craft. The first circle starts at 0 instead of 1.1, so a beginner with no skill at all can still try, and gains. The recipes are the 64 spells, listed whether or not the book has them, so a player finds what there is to learn; each takes the reagents the spell asks for when cast.

Change the rules

The recipes are data/crafts/inscription.toml, written by the converter from data/spells.toml and the table of circles; spell and mana are the two fields only this craft uses.
The tool is the template with script_id = "inscription_tool" (scripts/items/inscription_tool.lua): the pen and ink, whose graphics are pen_and_ink and 0x0fbf. The mapmaker’s pen stays a tool of cartography.
The failure and success texts and the sound of a craft are the tables FAILED_TEXT, SUCCESS_TEXT and SUCCESS_SOUND of scripts/common/crafting.lua; the crafts whose failure ruins one unit of every resource are the table FAIL_LOSES_ALL.
The staff bag .add test_kit_inscription holds a pen and ink, 100 blank scrolls, the reagents and a full spellbook; set the skills apart with .set skill inscription 100 and .set skill magery 100.

Existing roots

mgctl init never replaces a file you may have changed. Copy from the distribution data/crafts/inscription.toml, data/crafts/resources.toml (the list blank_scrolls), scripts/common/crafting.lua, scripts/gumps/craft_menu.lua, scripts/items/inscription_tool.lua, scripts/items/test_kit.lua, templates/items/test_kits.toml and templates/items/skills/tools/inscription.toml and templates/shops/mapmaker.toml (the mapmaker sells the mapmaker’s pen). A pen and ink that was a cartographer’s tool opens inscription now; cartography is opened by the mapmaker’s pen.

Not yet

Scrolls of the later expansions, bulk order deeds and writing a blank spellbook.

The scrolls of Magic Lock, Unlock, Magic Trap and Magic Untrap can be written but not cast: the recipes are there, and a scribe can make and sell them, but casting them says the spell is disabled until containers have a lock and a trap state (see Magery).
