There are 3 sizes of spell cases being sold by Master Brimstone in the Sto Lat Academy of Artificers:
So the larger and expensive the case, the more papers and spells it can keep.
Keep in mind that you can have only 1 spell case at a time. Two spell cases in the inventory will cause them to fight to the death.
Skills that TM: ma.sp.sp (special), ma.it.ta (talismans), ma.me.me.ch (channeling)
Syntax and gps costs of commands:
Channel
Syntax: channel [ink from] < object > into < case >
Costs: 25 gps
Since ink is kept and sold in bottles, channel bottle into case should work usally.
Empty
Syntax: empty case
Costs: number of spells*25 gps (see below)
Feed
Syntax: feed < spell > to case from my mind
Costs: 25 gps
Syntax: feed < quill/papers/scroll > to case
Costs: 0 gps/0 gps/(number of scrolls fed)*25 gps
List
Syntax: list spells in case
Costs: 25 gps
Remove
Syntax: remove < spell > from case
Costs: 25 gps
Retrieve
Syntax: retrieve [scroll of] < spell > from < case >
Costs: 25 gps
Restore
Syntax: restore < case >
Costs: 25 gps + as much GP as you have left. You may need to resotre the case more than once, depending on how much GP you have and the condition.
Feeding spells to the case
There are 2 ways to feed a spell to the case:
The first way seems to be just to take a spell scroll and feed it to the case. The case then eats the paper, unbounds the spells from the paper and has it stored within it. It will spit out a pile of shreddings, so the paper is destroyed in the process and not stored within the casel. There has not been any indication about which skill check is involved yet. Costs are 25 gps per scroll fed. Multiple scrolls fed at once cost (number of scrolls)*25 gps.
The other way is to directly build up a connection between the Wizard’s mind and their case. The Wizard first has to establish a connection between the own mind and the case, success is determined by a ma.me.me.channeling check. The more spells are already stored in the case, the harder the establishing of a connection will become.
If a successful connection has been established, the Wizard tries to split the spell in their mind up and make an additional copy which is then transferred to the case. As this is a question of spell handling, a ma.sp.sp check is being done, a successful splitting results in the Wizard keeping the original spell in mind and a copy of the spell being stored in the case, a failure pushes the spell from the Wizard’s mind into the case instead, i.e. the Wizard forgets the spell but the case now has it stored. So the spell is not lost, but the Wizard has to re-remember it, either from a tome, a scroll or by retrieving a scroll from the case again to remember it.
