I'm playing an Archivist Artificer (8) / Forge Cleric (2) in a short campaign. I was trying to figure out how or whether it is possible to create a spell scroll of guiding bolt (or any other spell from either class list).
Xanathar's Guide to Everything (pg. 133) says under the "Scribing a Spell Scroll" downtime activity option:
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.
The May 2019 UA Artificer's Archivist subclass gets the Tools of the Trade feature at 3rd level when they choose the subclass, which grants them the following benets:
Proficiencies. You gain proficiency with calligrapher’s supplies and the forgery kit, assuming you don’t already have them. [...]
Crafting. If you craft a magic item in the scroll category, it takes you a quarter of the normal time, and it costs you half as much of the usual gold.
From this, I have two questions:
- Which attack bonus would the scroll have? Would I use my Intelligence modifier, my Wisdom modifier, or nothing at all?
- How long does the scroll take to craft? Is "one day" of work treated as 8 hours of actual labor by by the character? If so, with the Artificer's 4x work speed and 1/2 cost, would that mean the total amount of time and money spent by the Artificer is 2 hours and 13 gp, for a 25 gp 1st-level scroll?
