But Rein thought about it and realized it's actually normal.
After all, his level 12 mastery of witchcraft is approximately equivalent to what a Wizard might achieve in ten or twenty years of diligently practicing a single witchcraft.

"So, Rein, what is your affinity with the Metal Element?" Master Mogaro excitedly grasped Rein's arm, his face turning red with blood rushing to his cheeks.
"Well... it's in the nineties." Rein thought for a moment and gave a conservative number.
Last time I measured it, it was about 93.6, but the problem is if my Steel Body Talent evolves again, this value could increase further.
So it's not wise to give an exact number now.
For example, the effect of the Dragon Bloodline might have already caused a change in the value.
