Spell book with flap
I can't believe it took me this long to think about adding a spell book into the clip art collection. I'm even working on a game called Invoke involving spells. Sometimes I think that I need to have coffee all day.
Most RPG games have some sort of wizard. And the mage should always have a spellbook for some kind in their equipment list. This clipart makes me think of what an Adventuring wizard might have amongst their possessions. In the image, I added a magic symbol that glows.
