This is a quill pen. It is all blinged as fuck, sparkling as it is turned this way and that. What you do is, you put all the materials needed to do your homework on a table or flat(ish) surface of some kind. Then you put the quill down on the table, utter the incantation, and the quill does the homework in your handwriting. Books, papers, the quill itself, all move magically to get the shit done. Put on your best Harry Potter glasses. That’s the vibe we’re going for.
It takes the quill the same amount of time it would take you to do the homework yourself. So you need to allow for that when you determine when you’re going to have the quill do the homework. Also, you get the benefits of doing the homework. That is, any improvements that would happen if you did the homework still pass to you if you use the quill.
You do not need to be present for the quill to do its thing. So you can set it to work and come back later when it’s all done.
