Can Cause Fear: This unit frightens all enemy units, reducing their leadership when nearby. It is also immune to fear. Fear penalties do not stack.
Norscan Ice Trolls is a Norsca monstrous infantry unit introduced in Total War: Warhammer. Mutations of the frozen north enable them to freeze their unfortunate victims with their foul, icy breath.
Ice Trolls originate further north than their counterparts from Troll Country. All Trolls have indiscriminate appetites and unthinking ferocity, and the northern variety are no different. With their great strength and regenerative abilities, the warlike Northmen find uses for Trolls in battle, despite them having rather limited intelligence. Most varieties are able to spew acidic stomach bile over their victims to inflict a nasty death, but the Ice Trolls’ proximity to the Chaos Wastes has caused this ability to mutate into something else altogether. With a single exhalation of their icy breath, they can instantly freeze their foes in their tracks, usually just before gobbling them up in a crunch of icy flesh and bones.
↑Frostbite: The intense cold cuts into the flesh and burns the foe's extremities, greatly reducing their speed.
↓Poor Leadership: This unit suffers from poor Lord or other encouraging units nearby.
↑Armour-Piercing: The damage of armour-piercing weapons mostly ignores the armour of the target, making them the ideal choice against heavily-armoured enemies. They are often heavier and attack at a slower rate though, making them less efficient against poorly-armoured targets.
↑Regeneration: Regeneration allows a unit to heal while in battle. Fire is known to harm this healing process, so be warned that flaming attacks will cause more damage to units with Regeneration.
Compared to regular Norsca trolls, these trolls have higher melee attack, the FrostbiteContact Effect, and more overall damage. They also gain 20 armour (40 to 60) which helps make them a bit more tanky. Ice Trolls are all around better than standard trolls, but come with a critical -20% fire weakness.
They are similar to the Chaos Trolls (Armoured) in that they are a good upgrade over the standard troll, but they are on a roster with much better monsters (Feral Mammoth) and monstrous infantry at that (Skin Wolves). For this reason, Ice trolls are primarily useful in a campaign army led by Throgg who gives them some nice bonuses.
