Joining Forces

Prior to the contestants' realization that the freezing temperature would affect even their flame, Crimson Heart had already noticed the main conflict of the environment. 

One, their reaction time and movement were definitely decreased by a large percentage.

Finally, the control of the flame temperature would test their mana control in retaining its power. 

All these conflicts were difficult even for those at the Master Level blacksmith. After all, nobody would be attempting to forge under such conditions with their expertise. 

However, this was a competition and whatever the conductor wanted to do, that was the final.
