Ophelia 29/34 AC:19, F:15, R:15, W:17

Ophelia yelps as an arrow hits her in the shoulder, then ducks beneath a second. Twisting to peer along the wall, she looks briefly pale at the sight of more ladders being thrown up, and cutting her off from her allies. She spots the other members of the group hacking their ladders to pieces, and takes a moment to smile ruefully at her spear. "Torgald always said I'd regret not using an axe."

Then Thanald's Flaming Sphere erupts to her side. As the light dances across the wall, Ophelia raises her spear over her head and twirls it with a cheerful whoop before bringing it down in a flare of blue light.

I was a little unsure of the idea of attacking a ladder, even a rope one, with a spear. I'm not sure freezing it and shattering it makes any more sense but...hey, a wizard did it!
