A few days later, Mira finished improving a few of her previous techniques to fit her current self better. The [Frozen Terrain Change], [100 Glacial Warriors], [Elemental Barrier], [Paragon Wings], [Frostbite Requiem], [Calamity's Embrace], and [Paragon Blizzard Obliteration] techniques all saw some sort of improvement, even if they were minimal.
However, it wasn't long before she ran into a roadblock. The problem wasn't with the [Frostbite Requiem], [Calamity's Embrace], [Elemental Barrier], and [Paragon Blizzard Obliteration] techniques, but with the other three.
All of them required her to create something or perform a semi-permanent action.
[Frozen Terrain Change] literally changed the area around her.
[100 Glacial Warriors] made a hundred golems that she had to control.
[Paragon Wings] created a pair of elemental wings behind her, with each feather having a unique property or effect.
