Eponine was sorely disappointed that the collapsing ice did not hit Byrea head on; still, a hit was a hit.  Again, she had to dodge the witch's ice attacks, activating her shield every time she knew she would not be able to dodge an icicle.  Eponine noticed her soul gem getting awfully dark, so at this point she had to make a gambit: keep fighting at this pace, risking the witch outlasting her and becoming a witch herself, or use the last of her magic save a tiny fraction in a powerful burst with the hope of ending this fight once and for all?  As Byrea began collapsing the ice in an effort to crush Eponine as Eponine had tried to do to the witch, Eponine decided upon the latter.  Summoning eight hammers, she placed them, head on the ground with the shaft pointing up, in an octagonal circle around herself, activating her hemispherical area force field.  She looked up and activated 'reject' so that every object that touched the field would be sent flying away in the opposite direction and at the same speed that it impacted, which would make the inside of the ice sphere something like a cross between a grenade and a pinball machine.  The world above her became a white and blue cacophony of clashing ice shards, bouncing pillars and bridges pulverizing into snow.  Eponine's breathing became labored and a sickening sensation crawled through her, which she assumed was magical in nature as she normally couldn't feel such discomfort, or perhaps it was just that painful that she could actually feel it this time.  She held out for as long as she could while the violent crashing continued but started to die down as the larger chunks had mostly broken into smaller pieces.  When just a sliver of her magic remained, when just a tiny part of her soul gem remained unblemished, Eponine deactivated her shield and, in fact, left her magical girl form completely, returning to the clothes she was wearing before she set out on this mission and quickly crouched down and covered her head with her hands, getting into a duck-and-cover position in preparation for what remained of the ice to come crashing down on her, resigned to let whatever would happen happen, hoping beyond hope that the witch had died.
