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.
Can Cause Terror: This unit can cause terror, making its melee target rout for a short time. Units that cause terror are immune to terror and fear themselves.
Encourage: This unit provides a leadership bonus to nearby allies. Units within range of both the Lord's aura and an encouraging unit will receive the larger of the two bonuses.
Hide (forest): This unit can hide in forests until enemy units get too close.
Unbreakable: This unit does not suffer any form of leadership loss and will never rout.
Halkenhaf Stonebeard is a Dwarfs melee infantry unique hero unit, only available to Clan Angrund. “No Troll, no Orc, no sneaky grobi scum shall bar my path. This time…”
With the Dwarf realm dwindling during the Time of Woes, Halkenhaf Stonebeard and his allies were initially successful in repelling the first few attacks against Eight Peaks. Like every gatekeeper before him, Stonebeard was a fearsome warrior, known for being able to move his axe with such incredible speed in battle that it would appear as a blur around him, like a rotor of a Gyrocopter in flight. Ultimately, the lesser warriors defending the Hold alongside him all perished, leaving him the last Dwarf standing. Refusing to leave his post, Stonebeard fought on, eventually meeting his end at the hand – or mouth, rather – of a hungry Troll. But it is said that he continued to swing his axe around wildly in a frenzy of slaughter, right up until he was picked up and swallowed whole down the monster’s gullet. With the gatekeeper defeated, the Citadel would be captured soon after.
↑Armoured & Shielded: Armoured units can block damage from any source apart from Armour-Piercing damage. Shields have a chance of blocking arrows, bolts, rifle shots and similar small arms fire - but only in a forward facing arc.
↑Ethereal: Ethereal units ignore most damage done by non-magical weapons. As they have shed most of their physical form, they are not slowed by terrain-based movement penalties either.
See King Lunn Ironhammer for general strategies involving the ghostly ancestors.
Stonebeard is another ethereal Thane which may suggest that he is the same as King Lunn. However, Stonebeard is more defensive in his stats. He gains 15 melee defence at the cost of 15 melee attack. His shield is also upgraded to 60% missile block chance. This is not super significant, however it does illustrate differences between the two. If one wants a more defensive and tankier ghost unit, then Stonebeard is your Dwarf.
