From the demon's point of view, they were cheating. Cheating in a most underhand and ungentlemanly manner. It was annoying and frustrating. After the first 30 minutes of shouting "Test of icycles!" he stopped, realising his defeat.
We can see our champions casting fireballs, and have been now for the past 3 hours. Some of them are throwing them everywhere. The frost encrusted fur of Daroou had melted to a wet mat, and the floor around his feet had become a cold, soggy, sludge of inconvenience. It was safer that way of course, as the raising temperature and the hurling of fireballs dislodged some of the icycles and sent them crashing down to the cavern floor one at a time. It had basically been 3 hours of casting mana potions or fireball spells along a 2 meter wide corridoor across the cavern.
"Can I hit him first?" inquired Daroou. The others told him to be patient, and wait his turn.
When they finally got to the other side the demon did nor said anything. They quietly passed him by, ignoring his agitation.
To 119 then, and leave the cold glare of the demon.
