Ice Weapons

Ice Trolls are not creatures known for extensive planning and are often distracted by pretty rocks and sunlight glinting off the northern ice. However, the Trolls occasionally muster enough foresight to fashion crude arms for themselves for later use. Generally, these weapons take the form of spears or clubs made from large icicles or of axes created by attaching sharpened sheet ice onto a wooden haft. These weapons have been known to shatter in combat, and many a soldier has fallen with a shard of ice protruding disgustingly from his body.
On the turn in which Ice Trolls charge, any Ice Troll roll of 6 to hit indicates that part of the Ice Weapon has shattered off and could potentially cause harm to the enemy. Thus, any roll of 6 to hit on the charge will cause an additional S3 hit. If the unit of Ice Trolls at any time takes damage from a fire-based attack, the ice will begin to melt, and the Ice Weapons count as normal hand weapons thereafter.
