If below 40% of the energy was stimulated, that would be a low-level talisman.
The energy an exorcist could transform varied depending on their skill level.
However, an exorcist of any level could feel the waves of energy coming from a talisman.
As such, they could determine the level of this talisman.
What Luo Dingzhen saw that day were ready-made talismans Xie Jiling had taken out.
He knew that Xie Jiling was from the Xie family, so he wasn't surprised to see that she was holding a high-grade talisman seal.
However, Luo Ding really thought that they were given to Xie Jiling by the elders of the Xie family.
He didn't expect that these were all drawn by Xie Jiling herself.
Xie Jiling could draw high-level talismans. However, there were different high-level talismans.
Any talisman that could generate 70% of the energy from the symbol would be considered a high-level talisman.
