[Eon's POV: ]
The Bullions were powerful creatures. It was quite difficult beating them in a game of strength.
'I thought they would simply be as strong as Rein, but I didn't think the addition of Spirits would make so much difference.'
Those creatures were quite different from many other spirits using creatures I've fought. Unlike the normal creatures that share their energy with the spirits so that they can materialise into the physical world and help them, they harnessed the powers of the spirits itself.
'Much like an Elementalist, they had a unique bond with the spirits.'
They can use the (Spirit connection) to connect with the spirits and use their Mana to channel the powers that they have throughout their body.
