You have to open the objectcreationlist.inc. There is the "ObjectCreationList OCL_SpawnSummonRogash" ,where you change the Count of the Troll and where you can delete the summon of Rogash.
For Building Rogash, you have to open the playertemplate.ini and then you have to add Rogash in the "BuildableHeroesMP" of Faction Angmar at the last place. Afterthat you have to change the commandset of the building, where you want to build him.
For example the normal Angmarbarrackscommandset:
CommandSet AngmarBarracksCommandSet_Edikt
InitialVisible = 8
1 = Command_SelectRevivablesAngmarBarracks
2 = Command_ConstructAngmarDarkDunedainHorde_Edikt
3 = Command_ConstructAngmarDunedainPikemanHorde_Edikt
4 = Command_ConstructAngmarDarkRangerHorde_Edikt
5 = Command_ConstructAngmarNumEliteHorde
6 = Command_Sell
7 = Command_ConstructAngmarSchwarzeRitterHorde
8 = Command_PurchaseUpgradeGemächerderSchwarzenGarde
9 = Command_FakeRingHeroReviveSlot
10 = Command_FakeCreateAHeroReviveSlot
11 = Command_FakeHeroReviveSlot1
12 = Command_DurmarthReviveSlot
13 = Command_FakeHeroReviveSlot3
14 = Command_GenericReviveSlot4
15 = Command_FakeHeroReviveSlot5
16 = Command_FakeHeroReviveSlot6
17 = Command_FakeHeroReviveSlot7
18 = Command_FakeHeroReviveSlot8
19 = Command_RadialBack
End
and the changed Commandset
CommandSet AngmarBarracksCommandSet_Edikt
InitialVisible = 8
1 = Command_SelectRevivablesAngmarBarracks
2 = Command_ConstructAngmarDarkDunedainHorde_Edikt
3 = Command_ConstructAngmarDunedainPikemanHorde_Edikt
4 = Command_ConstructAngmarDarkRangerHorde_Edikt
5 = Command_ConstructAngmarNumEliteHorde
6 = Command_Sell
7 = Command_ConstructAngmarSchwarzeRitterHorde
8 = Command_PurchaseUpgradeGemächerderSchwarzenGarde
9 = Command_FakeRingHeroReviveSlot
10 = Command_FakeCreateAHeroReviveSlot
11 = Command_FakeHeroReviveSlot1
12 = Command_DurmarthReviveSlot
13 = Command_FakeHeroReviveSlot3
14 = Command_GenericReviveSlot4
15 = Command_FakeHeroReviveSlot5
16 = Command_FakeHeroReviveSlot6
17 = Command_FakeHeroReviveSlot7
18 = Command_FakeHeroReviveSlot8
19 = Command_GenericReviveSlot9
20 = Command_RadialBack
End
You have to change the commandrangecount, too, of the CommandButton Command_SelectRevivables AngmarBarracks from 11 to 12.
CommandButton Command_SelectRevivablesAngmarBarracks
Command = PUSH_VISIBLE_COMMAND_RANGE
TextLabel = CONTROLBAR:SelectRevivablesMenFortress
ButtonImage = UCCommon_EvilHeroes
ButtonBorderType = SYSTEM
DescriptLabel = CONTROLBAR:ToolTipCommandSelectRevivablesAngmarBarracks
Radial = Yes
CommandRangeStart = 8
CommandRangeCount = 12
End
