Silent Strike
Thanks to the powerful enhancement provided by Selene, her spell was truly powerful, hurting the weakest among those present. At that moment, Selene, without any enhancement, also cast an ice spell to defend and hold back, those who overtook Eira's attack.
Selene had no affinity, so she relied on her use of runes, which she was surprisingly good at despite how she acted. The same was true of smithing; her younger sister was a prodigy at many things but common sense.
Certainly, both had always learned what the other should, thanks to her skill. Oddly, however, Selene had always been good at magic despite having slow mana growth and having skills that would be for a warrior, while Eira, was good at close combat.
Despite only being able to increase her strength reasonably with the mana breathing exercise, it was as if her talents had been reversed.
