So you played the adventures of wismerhill, eagerly waiting to unlock the Lords of Negation in the Black Moon campaign,
only to realise you won't unlock them...ever...UNLESS !!

There IS a way...BUT you won't be able to buy them from the barracks (the store bulding for units if i'm not mistaken).
If you try to buy them the game will crash close and return to windows.
There's still mystery to this but, one step at a time my friends!
If your precious Lords all die you will have to add them back up using the method below.
But that's not gonna stop us from having what we want !

We're going to need to add the lords of negation to the list of units usable in the campaign,
otherwise, if we tried to add them, the game will crash close on booting your save, saying something like:
"the object section number 6 isn't in the player's camp".

[We're also gonna fix a little bug : in skirmish, the lord of negation icon and the baron of moork icon are swithed up]

Go to:
Black Moon Chronicles\BlackMoonEN\Skirmish\Sections\Lune_Noire
open the file : Lune_Noire
fix a little bug:
find the lines both in [SECTIONS] and [UNITES]:
"Lord of negation" .... 39...
"Baron of Moork" ....44...
And exchange those values between them:
"Lord of negation"....44
"Baron of Moork"...39

The correct icons will now appear when choosing those units in skirmish.

Now, you can copy paste what i did below but gog screws up the spacing so i advise you to do it your self rather than copy pasting my stuff.

Copy the entire line of the lord of negation in [sections] and [unites]
still in :Black Moon Chronicles\BlackMoonEN\Skirmish\Sections\Lune_Noire

then add them to:
Black Moon Chronicles\BlackMoonEN\Campagnes\Lune_noire\Sections\Lune_Noire
Tried to modified the lines to be more like the others in the campaign files by add/delete a few tab spaces:

Change:
[SECTIONS] 9 to [SECTIONS] 10 (as we are adding one unit.)
Add the line:
"Lord of Negation" "LUNE_NOIRE___SNEG" "" 44 3 10 0 1PA 1PA 1PA 1PA 2PA 0PA 0PA 1PA 0PA 0PA - - - - - - - - - ( I added the line after the giant, but i don't think it matters where you put it)

Change also:
[UNITES] 10 to [UNITES] 11
Add the line:
"Lord of Negation" "LUNE_NOIRE___SNEG" "" 44 3 18 1 1

NOW YOU CAN ADD THE LORDS TO YOUR PARTY 2 WAYS:

_1.CHANGE YOUR BASE REGIMENT:
you will define what you start whith in the black moon campaign ( NOT available at start, you'll need to do a PRETTY LONG INTRO !!! BE AWARE!!)
Go to:
Black Moon Chronicles\BlackMoonEN\Campagnes\Lune_noire\Armee\Regiment0
this what you star whith if you do new game-campaign-black moon.
you will see at one point:

Section__nom =Orc
Section__numeroObjetMaitre 10
Section__niveauChateau 1
Section__nbUnites 6
10 0 500 500 100 100 10 0 0
10 0 500 500 100 100 10 0 0
10 0 500 500 100 100 10 0 0
10 0 500 500 100 100 10 0 0
10 0 500 500 100 100 10 0 0
339 0 500 500 100 100 10 0 0

this above is one "section" or unit even if there are 6 orcs per unit.
we need to change it to one 1 unit of lord of negation, so one lord:

Section__nom =Lord of Negation
Section__numeroObjetMaitre 6
Section__niveauChateau 3
Section__nbUnites 1
6 0 500 500 100 100 10 0 0

Now, you can add more units (max 8) but be carefull to adapt the "Regiment__nbSections X" to fit the number of "sections" or units you have,
the starting regiment has 6 sections in it, a full regiment has 8.

So you can change it into this:

Regiment__nbSections 8
Section__nom =Lord of Negation
Section__numeroObjetMaitre 6
Section__niveauChateau 3
Section__nbUnites 1
6 0 500 500 100 100 10 0 0
Section__nom =Lord of Negation
Section__numeroObjetMaitre 6
Section__niveauChateau 3
Section__nbUnites 1
6 0 500 500 100 100 10 0 0
etc x8 times

Save of course, then when you lauch a black moon campaign your starting regiment will have 8 lords of negation ! Prrrretttty cool !

_2.CHANGE YOUR CURRENT REGIMENT:
In your save folder:
Black Moon Chronicles\BlackMoonEN\Sauvegarde\sauvegarde01\Regiment0
open regiment0 or any other regiment you have (your starting regiment beeing regiment0)and, like above, you can replace a "section" by the "lord of negation" one:

Section__nom =Lord of Negation
Section__numeroObjetMaitre 6
Section__niveauChateau 3
Section__nbUnites 1
6 0 500 500 100 100 10 0 0

If you want to find this "lord of negation" section yourself go in the game and create an army with "lords of negation" in skirmish mod,
you will then be able to find the lord's "section" in :
Black Moon Chronicles\BlackMoonEN\Armees\Escarmouche\LuneNoire\TheNameOfTheArmy

Hope you'll enjoy !!!

Wow, nice find! Thanks
