Mobius Scroll

The "mobius scroll" is a half-twisted length of
paper that's been magically connected to itself
to form an infinite, continuous sheet. The scroll
is blank when found. A spell appears on it when
you first attune to the scroll and then again daily;
roll a d8 each time and use the table to determine
what spell appears on the scroll. On a 8, an extra
spell appears on the scroll. You can read from
the scroll to cast a spell from it using an action.
