So as I drew up the DW version of the Scroll-Caster, I had to look at the Common Scroll from the Magic Items section of the book. I noticed two things:
1. The spell on the scroll has to be castable by you or on your spell list, but do you actually roll the Cast a Spell move when you use the scroll? “The spell takes effect, simple as that”?
2. The spell remains on the scroll after it’s first used? The spell/scroll isn’t consumed in the casting?
(I am referring to using the scroll without my Scroll-Caster; just sharing its original post for ease of reference).

This silver tube, engraved with an intricate artistic pattern, appears at first glance to be an elaborate scroll case. The caps on either end are each set with a roughly-hewn onyx, bound in silver wire. When a common scroll is in the tube, and both ends caps are fastened, the wielder can sense the arcane energies present and harness them as if they were a spellcaster.
When you gesture with the scroll-caster in hand and speak the command word, roll+INT. On a 10+, the spell scribed onto the scroll is successfully cast (as if it were castable by you or on your class’s spell list). On a 7-9, the spell is cast, but choose one:
• You draw unwelcome attention or put yourself in a spot. The GM will tell you how.
• The spell disturbs the fabric of reality as it is cast—take -1 ongoing to using the scroll-caster until you wait for a minute or two and let reality settle back into place.
• After the scroll’s spell is cast, the scroll is depleted, leaving behind an ordinary sheaf of parchment.
