After losing the support of the legendary formation, Kolhdre lost his above level 700 combat prowess. But at the same time, Mio also received a backlash for losing so many for her summons so quickly and her stats temporarily went down by a notch too. So at the current moment, both of them had very similar stats. So the final outcome of this battle would depend on their ability to utilise their power.
To get ready for the final showdown, Mio summoned two of her only remaining weapons. One was a large hammer and another one was a giant axe. Actually Elena was not very good with both of these weapons. Large and heavy weapons like this were very uncomfortable for her to use. That was the reason she decided to use these two weapons as her final one. It was an act of nerfing herself a little bit.
