I just found out how to summon things.

Check out the system.ini, yuri. And then objectcreationlist.ini.
Edit: But what is "SPECIAL_SPAWN_OATHBREAKERS" in SpecialPower.ini? If I search all Ini's, I can't find the same phrase anywhere. When I added all the spawn_minorspiders stuff everywhere, it gave the error:
Token 'SPECIAL_SPAWN_MINORSPIDERS' is not a valid member of the index list
Error parsing field 'Enum' in block 'SpecialPower" in file 'Data\INI\SpecialPower.ini', line 53.
I know I still have to add something somewhere in order to make it work.. But I can't find "SPECIAL_SPAWN_OATHBREAKERS" so I don't know where to add it. ; ;
