The Hie Hie no Mi... Linnea clenched her fist and looked on as it turned to ice, starting from her knuckles, down to her forearm. This power, this ability to turn her entire body to Ice, this was all the power she needed for even someone with a weak body like herself to make a colossal difference on these seas. But if the Legendary power of Devil Fruit ability was to be manifested through her, she had to master it. At this point, the Uroboros Captain had only begun to scratch the surface, learning to freeze enemies and objects on contact, and at least a rudimentary ability to produce Ice. She hadn't learned to mold that ice effectively yet, and even if that didn't make her fruit weaker, it defenitely made it less worthwhile to use; compared to the Archery she'd trained and expanded all her life.
This islet far off shore Ennies Lobby proved a perfect place for her next training session, and while her crewmates were off exploring on their own, she decided to enjoy this gorgeous sunny weather a bit more, and walk around the beach in a bikini. It was indeed gorgeous, a whole other kind of treasure that Linnea had originally set out to see for herself. Amidst the thin white sand, she found an isolated reef that would serve her purpose perfectly.
Once more activating her devil fruit power in both hands, she produced thin rods of ice from her two fingers, pulling on them with a faintly strained expression as she learned how to control her Hie Hie no mi. Crafting arrows with her devil fruit ability? She was a logia, said to be able to produce near infinite amounts of their element: If she couldn't make something as simple as an arrow, she was gonna have a hard time figuring out more complex techniques. This was a good way to start her endeavor of empowering her archery with Ice. Up until now she had been using the fruit's abilities on their own, as if they were just another weapon. But this was more than a weapon: Her body WAS Ice. Why couldnt she be use this part of her body like any other. And so, Linnea tugged on her finger more and more, until she finally produced something vaguely shaped like an arrow, and snapped it at the base. It didn't hurt at all like it might seem at first, even if the cracking sound was eerily similar to what the real thing might sound like.
Drawing her bow, she levelled it with a crook in a nearby rock, and took aim...
Frost arrow:
