Icy Cold

Normally swimming wouldn't be a challenge for her. She's been swimming all her life. But that was at the temple, in warm water, wearing less clothes and never in armor.
Her armor weighs her down, her winter clothes soaking in the icy river water, adding to the weight. The surface keeps drifting away, despite her struggles. She stops fighting, hoping, praying the others in her party notice she fell through the ice mid-battle. Conserve strength. Got to conserve strenght.
The cold starts eating at her core and she desprately needs air. She reflexively breath, taking in a lungful of ice water. She starts panicking, the ice stabbing her core. Up! I need up!
She feels a pull on her magic. The water underneath her becomes more solid and she starts rising. In under a minute, she breaks the surface, the water shoving her back onto the ice.
"Kara!" She hears Nav'iid shouts as she blacks out.
