Scroll, common
A spell scroll bears the words of a single spell, written in a mystical cipher. If the spell is on your class’s spell list, you can read the scroll and cast its spell without providing any material components. Otherwise, the scroll is unintelligible. Casting the spell by reading the scroll requires the spell’s normal casting time. Once the spell is cast, the words on the scroll fade, and it crumbles to dust. If the casting is interrupted, the scroll is not lost.
This scroll contains a cantrip. The spell's saving throw DC is 13 and attack bonus is +5.
Notes: Utility, Consumable
Could these potentially be used by any class?
Rules as Written, you can only cast from the scroll if the spell is on your class's spell list of if your character has some kind of feature that allows them to bypass that requirement such as an Artificer's: Magic Item Savant feature or a Thief Rogue's: Use Magic Device.
Obviously a DM can rule otherwise.
The rule book states quite clearly that a wizard can copy spell scrolls to a spell book. It also states quite clearly that a Cantrip scroll is a spell scroll, level 0.
The problem I have is what next? Assuming you don't already know it
Can you learn it?
Can you make more cantrip scrolls from it?
or is it just a one shot thing that you shouldn't copy to your spell book, despite what the rules clearly say?
Cantrips do not exist within spellbooks.
Do the cantrips in spell scrolls scale with character level? E.g. would a level 5 wizard casting fire bolt through a spell scroll deal 1d10 or 2d10 damage
