Lucius spent the next several hours inside the laboratory creating the Spell Matrix, formulating and crafting it with careful precision and avoiding even the most inane of errors and slips.
He had to stop several times and check if each corner of the matrix was according to its original design.
It was something difficult even for him but he persevered until he finished it.
Once Lucius was done, he quickly checked on the other spell matrices in his mind space. All of them were still intact and none of their integrity was actually affected.
But Lucius still needed to test it.
Lucius raised his hand, forming a small and swirling fireball within it, and was satisfied to see no damage to its spell matrix whatsoever and he did the same for each one of them.
No cracks or damages occurred which pleased Lucius greatly.
