Downtime Activity: Scribing a Spell Scroll
Source: Xanathar’s Guide to Everything p. 133
With time and patience, a spellcaster can transfer a spell to a scroll, creating a spell scroll.
Resources
Scribing a spell scroll takes an amount of time and money related to the level of the spell the character wants to scribe, as shown in the Spell Scroll Costs table. In addition, the character must have proficiency in the Arcana skill and must provide any material components required for the casting of the spell. Moreover, the character must have the spell prepared, or it must be among the character’s known spells, in order to scribe a scroll of that spell.
If the scribed spell is a cantrip, the version on the scroll works as if the caster were 1st level.
Complications
Crafting a spell scroll is a solitary task, unlikely to attract much attention. The complications that arise are more likely to involve the preparation needed for the activity. Every workweek spent scribing brings a 10 percent chance of a complication, examples of which are on the Scribe a Scroll Complications table.
