"Think of your mana as a river. Right now, it flows as one body, reaching your limbs, senses, and skills. This is what everybody learns instinctively as they grow up and raise their level. However, [Mana Channelling] teaches you to carve a second riverbed."
As they say, a hint is enough for the wise, some knights instantly understood the reason behind their learning all these skills. As for those who were still at a loss, Reinhardt continued.
"From now on, you will try to create two mana reserves, one for yourself, the other one for your divine beast. This reserve can be filled gradually, and it will become your second origin"...
"When the time comes, you can instantly activate them to summon your beast and support them using your reserved mana pool and not from your primary mana pool that is essential for your own survival."
Having explained this far, even the clumsiest ones like Vangeance got the meaning behind their training.
