Looking Idun over, Annika would find no spirit with her, although if she had the means to detect other supernatural things, she'd find both Idun's equipment and Idun herself fell in that category.
With the shield limiting her field of vision when charging at Annika, and the bear landing rather silently when it hit the ground, Idun wasn't aware the bear was behind her, and so it wouldn't have a very hard time hitting her. She shrieked as the flames licked her lower back, the fire beginning to melt the synthetic material the runner's top was made of, the hot slack sticking to Idun's skin.
Gritting her teeth, Idun jumped to the side, putting a fair amount of force in the jump, landing roughly half a metre away from Annika, and closer to the bear. From there, she wheeled around to an angle where she could keep an eye on both Annika and the bear, raising the shield towards the bear to protect her torso.
With the minimal size of the fire spirit, Idun didn't bother trying to hit it, instead, she opted for a different tactic. Moving her right hand so the wrist was pressed against the side of the shield, another magic circle appeared in front of the hand, the old Nordic text in this one reading "Banish. Cast out. Spectre."
Unlike the previous two spells, this one didn't form a second circle around the fire spirit. Instead, a white beam fired out at it from the centre of the circle. If the beam hit the fire spirit, depending on how strongly its ties to the mortal world was, it would either be cast out, or have said bonds weaken.
While not moving at light-speed as one might expect, the beam did travel roughly twice as fast as most 9mm bullets.
