"Invisibility Charm, Immobilization Charm, Fiery Fire Talisman...wow, there's even a Ghost Exorcism Talisman, haha, I really want to try out the effects of these talismans right now."
The Talisman Secret Skill recorded the methods of making various charms, and the talismans mentioned here were nothing like the ones used by street magicians to deceive people. All talismans in the Talisman Secret Skill required the caster's own mana to be infused into them. The decisive factor that determined the effectiveness of a talisman was the strength of the mana.
In other words, the stronger the talisman drawer's own mana, the more powerful the talisman they create would be. Conversely, if a talisman drawer's own mana was weak, then the talismans they produced would not be very effective.
