A Hard Spell To Master

'Monsters... don't have a simple way to measure up their strength and energy,' the old man paused before adding, 'see your Don here for instance, he had a large amount of power stored inside him with such a small body and young age. Monsters work in a much more complicated way than you think.'

"So the bigger the size the higher the energy, right?"

'Wrong,' the old man firmly said, 'haven't you heard what I just said? You can't judge them using the same methodology of magicians.'

"Then... how can I know if I can absorb a monster's energy or run away from it?" Jim was puzzled by this.

'The only way is to fight it first hand,' the old man said, 'this way I can help to inform you roughly of my estimation.'

"Roughly?" Jim noticed the strange word his old man used, "that doesn't look promising."

'At least it's something,' the old man sneered, 'better than running around and trying your luck. Sometimes your luck might be bad.'
