The Book of Mantras had never been upgraded to an Extraordinary Magic Tool in the future. The greatest value of the Book of Mantras then came from its endless incantations. As long as one was patient, it was possible to find some very powerful spells.
But the true value didn't lie in those powerful incantations, but in the fact that there was an endless number of incantations. As long as they were meticulously studied, the understanding of each rune would reach an inconceivable realm.
This was like a poet... They had to master words to create a poem, and they had to learn how to arrange them in a graceful manner.
Words were known to everyone, but few people could use these words to create poems.
The incantations were the poems, and the runes were the words. Every mage knew them, but very few could use the runes to create their own incantations.
The created spells could be very powerful or have special value, but there were extremely few of them.
