Just his luck, Bjorn thought as he felt his armour chill. He wouldn't be able to get it off in time, so he decided that moving to towards the fire was the better option. His axe and shield would be unaffected and so would his bow. So until such time as those critter would come closer, he would shoot at them and try to get them down to size, or down-er to size.
