The Cursed Company is Undead, and as such the following rules apply to them:
Leader
If Richter is killed, the Cursed Company will quickly begin to crumble to dust. At the end of the phase when Richter is killed, and at the beginning of each of their turns thereafter, the Cursed Company must take a Leadership test. If the test is failed, the unit suffers a number of wounds equal to the number they failed the Leadership test by. No saves of any kind are allowed against these wounds.
Break Tests
The Cursed Company cannot be broken. If the Cursed Company is beaten in combat, it suffers one extra wound for every point they lost the combat by, with no saves of any kind allowed (remember that with the Banner of Malediction, this number is reduced by one).
Immune to Psychology
The Cursed Company is Immune to Psychology. The only exception to this is that Richter Kreugar hates Undead.
Charge Reactions
The Cursed Company can only react by holding their ground.
Marching
The Cursed Company can march as long as Richter is still alive. If Richter dies, the Cursed Company cannot make march moves.
Cause Fear
The Cursed Company and Richter cause fear.
