An in-depth explanation of a Level 1 Rule Rune could be exchanged for 1 "Academic Point", which was not cheap by any means.
To have 12 Level 1 Rule Runes, one needs 12 "Academic Points".
But this was an essential expenditure.
Despite the difficulty of earning "Academic Points", Link spent them without hesitation and reluctance.
After browsing through the detailed explanations, Link arranged them in order of difficulty based on his impressions.
Then, he read through each one in detail, going from easy to hard, gradually increasing the difficulty.
To thoroughly understand 12 Level 1 Rune explanations was not something that could be done in a short amount of time.
It would need at least a month's time.
Only Link, who possessed the "Mind Closure Technique", the Hall of Mind, and the Talent for Spell Casting Studies, along with his own decent qualifications, could possibly make it.
