Fur Coat: Yeti fur keeps you warm but is flammable. You are resistant against Cold damage. If you take Fire damage you have disadvantage on attack rolls and ability checks until the end of your next turn.
General Description
A recent addition to the world and few in number, these are a collection of Trolls which have been interbred with Yeti. Their skin tends to the bluer shades of grey, with white hair or fur which allows them to resist some of the cold in the Ice Palace, however this is notably less soft than true Yeti fur and can not be used to line boots. Otherwise, they are not all that different from other Trolls.
Fire
Ice Trolls are noted to be even more weak to fire than ordinary Trolls, thanks to their hair and other cold-weather adaptations making them overheat quicker and their hair making them more flammable.
