Arran spent an entire month going through the thousands of Forms contained within the amulets, committing them to memory as best he could.
With the amulets safely in his possession, there wasn't any real need to do so — not when he could look up the information whenever he wanted. Yet after losing his supply of dragon meat, he had come to realize that he'd put too much faith in the void ring's protection.
Whether he carried it with him or hid it, there was always a risk that it could be damaged, lost, or stolen, its contents lost to him forever.
That was an unavoidable risk with material items, but for the Forms, he had one truly safe place to store them — his own mind. And if that meant spending an entire month memorizing the amulets' contents, the time it took was well worth it.
But unfortunately, memorizing the instructions was a very different thing from truly learning the Forms.
