Rings of the Secret Scribe (Patreon)

Ring, common

This pair of rings only function when worn on adjacent fingers: typically on a thumb and forefinger. While pinching the two fingers together, such as when pantomiming writing with a quill, you can magically write on any surface within one inch of your fingers. The writing itself appears in nonmagical ink in a color of your choice.

Lemme make a note of that.
