Have use as a material used in some sort of crafting mechanic.
Now, there are higher rarities of Ancient Scrolls, as Dark And Darker Gold some players have reported seeing green, blue, and even purple variants. Sadly, these ones are also pretty much worthless, and it's unclear if they sell for any more than the basic 'flawed' version does.
What Could It Eventually Do?
Dark and Darker - Showing Ancient Scroll Item Description In Inventory
To cap things off, let's do a bit of theory crafting. The Ancient Scroll is one of the only items in the game to have such a unique appearance but without a function, so it's clear that the developers of the game probably plan to give this item some function at some point. With that in mind, what purpose could this item eventually serve? Well, based on what's been shown of the game so far, here are some of the things the community seems to think the Ancient Scroll is eventually going to do:
Hold a single use of a spell so non-magic classes can use magic in a pinch or Wizards can cast an additional spell they didn't already have equipped.
Contain some amount of experience for quicker leveling.
Serve as an item in some future event they have planned to be exchanged for the event currency.
Have use as a material used in some sort of crafting mechanic.
Fulfill some role in activating some game function, such as summoning a boss if used in a certain area or opening some ancient doorway that would otherwise remain locked.
Again, it's unknown what the actual plans for cheap Dark And Darker Gold this item are, but there are plenty of routes the developers at Ironmace could go down.
