Whirlwind Spear (旋風槍 Senpū yari) is a Class Strike technique used by Riesz in Trials of Mana. She learns this tech by default in her starting Amazon class. This tech allows her to thrust her spear to generate a small whirlwind in front of her to strike foes in range
Riesz's body will turn white in color momentarily as she spins her spear above her head. She will then thrust her spear forward, with the resulting cyclone cutting any foes within a short range radius around her.
