- Hand the NPC one MMD note, and then hand a level VIII spell component you don't want for a new random component. Handing in one type (ink, glyph, quill) does not assure you will receive that same type.
- The exchanger mostly gives glyphs but is confirmed to occasionally give inks and quills (unlike the chests the components appear to all have an equivalent chance of being given, which makes quills at only 4, very rare). This changes the calculus of using burden on chests, before glyphs were most desirable, but now quills and inks probably are since you will need them to make scrolls.
