Fear

Wights are evil and unnatural creatures which cause fear as described in the Warhammer rulebook.

Immune To Psychology

Wights are not affected by psychology themselves. They are immune to fear, terror, panic and all other psychology tests.

Break

Wights who are beaten in combat and fail their break test are destroyed. The magical hold that their master has over them is destroyed and they crumble to dust.

Wight Blades

Wights are armed with ancient enchanted swords, or other evilly enchanted weapons. These are magic weapons and any blow from a Wight's sword will drain the life away from its victim, causing not 1 wound on the individual but D3 (roll a D6: 1-2 = 1, 3-4 = 2, 5-6 = 3).
