Soon, the two Dragon's shared their Spell Models with the two. They used some kind of magic similar to the books in the library of the Academy.
Nevertheless, it felt as if they used a memory transfer spell to show them what the Spell Models looked like. It was certainly more effective as the image of the Spell Models was very clear.
They were Draconic Scale Armor, Dragon's Roar, Draconic Breath, Dragon's Wrath.
The Draconic Scale Armor could be used by humans and it grants the caster a layer of scales that covers their skin, similar to a dragon... It can be used to protect against physical or magical damage, or to enhance strength and durability.
However, even if humans could record this Spell through some luck, they would not be able to utilize it with its full might because they are missing the Dragon's blood and physique.
