Misdirection array.

"According to the system, the reason why we haven't been taught about it is that breaking an array involves having profound knowledge of the said array and having a lot of mana control required to cast the breaking spell and all these are things we lack." Blake relayed the words of the system to them.

"So how are we meant to break the array if we don't have the requirements?" Blake asked the system.

[I never said you didn't have the requirements, I meant them.] The system said pointing at Castiel and Brian.

'Huh?' Blake was lost by the system's words.

[The most important requirement needed to cast the array breaker spell is mana control and out of you 3 you are the closest because your willpower and mana control are greater than those of your peers due to your extracurricular training.] The system explained.
