thank you so much for the kind comments and the feedback! if/when we update the game, we will definitely look into refining the tome's lock mechanic.
as for a couple of code hints: the 5 symbols of the password do not repeat, so 1 symbol is unused. look for items and environmental clues that depict a number or ordinal. let us know if you need more help!
if the bookshelf, desk, and general attic area don't seem to have any obvious clues, pay close attention to runi's dialogue -- sometimes their musings are more than just flavor text.
if the 5th symbol isn't one of the remaining ones in your current attempt, then i'd suggest thinking over the other 4 symbols and what made you so sure about their position. there might be something you missed. but we promise the answers are all in this room!
