Noland Lee's "sense tampering" was at 100-level.
For the ten times he received an additional reward for each ten levels, he chose "Option One: Extend the tampering duration."
For the family secret guard, the first time Noland Lee cast "sense tampering" on such an eighth Circle wizard, the tampering effect would last about 12 seconds.
The second time he used it, the tampering effect would shrink to 9 seconds.
The third time it would be 6 seconds.
And so forth.
By the fifth time, the family secret guard would become immune to "sense tampering."
Noland Lee would have to wait about a minute for "sense tampering" to take effect again, but the duration would only be 3 seconds.
After the 3 seconds were up, Noland Lee would have to wait another minute for the "sense tampering" to restore its effect.
Simply put, consecutive casting of "sense tampering" could control an eighth Circle wizard for about 30 seconds.
