Overwhelming Presence

On his way back, John placed his hand over his chest, he didn't know why, his emotions should have gone dull after going into the possessed state, but his chest hurt. 

Before thinking any deeper about it, He focused on the boss, it wouldn't take long before it noticed that it was fighting an illusion. 

But what stood out the most was the power flowing through him, along with the immense amount of knowledge which he couldn't even process. 

He didn't know why, but when he used the illusion spell it felt natural, on top of that, he felt like he could use all the other spells he had memories of, without the need for chants. 

Knowledge of the words which he would need to say, and knowledge of the spell itself, on top of that, with his understanding of concepts, it wouldn't be a stretch to say he wouldn't need any chants for a few of them. 

However, the total number of spells he could use right now were only 6, and they weren't normal.
