'That is the case, master. It is the union of the nine demons, the maximum this formation can provide. So if the mana creature before you falls, you'll be free.
As for how to defeat it, there are only two ways. One is to destroy the formation's core, as I've already said. The second is to defeat it with a power even more robust than its own.
Unfortunately, the master has the same power this creature would have if it were a Low-level Mage. But it's as strong as a Mid-level Mage, maybe even close to a High-level Mage. In this case, there's no way the master can beat it with your normal powers.
Unless you have a pill that puts you into Rage Mode, there's not much you can do except try your best to destroy the core of the formation.'
Rage Mode was a name for a unique state in which magical beings temporarily increased their strength through special methods.
