Ok, you have the options by calahan and want to test them out. But is the pretender too costy? Allow me to help! Copy this piece of code into some old mod.dm file you have lying around and edit it to make your pretender happen! (you can open & edit .dm files with a simple notepad or any equivalent)
Remember to activate CBM first, and after taht the mod you edited to include this piece. (so that all changes the CBM makes will be included in this new pretender)
Code:
#newmonster 2951
#copystats 1011 --- Set the monster number of the pretender in question here. You can see the monster number by clicking Shift-i while viewing the pretender in-game
#copyspr 1011 -- This command tells the game what moster sprite it uses for the unit. Should be the same as the copystat.
#name "This quoted text is example" -- This gives the monster a name. The name needs to be insade the quotes or **** will happen.
#magicskill 0 0 -- This command sets starting skill in FIRE magic. Set the amount by replacing the rightmost number (0).
#magicskill 1 0 -- This command sets starting skill in AIR magic. Set the amount by replacing the rightmost number (0).
#magicskill 2 0 -- This command sets starting skill in WATER magic. Set the amount by replacing the rightmost number (0).
#magicskill 3 0 -- This command sets starting skill in EARTH magic. Set the amount by replacing the rightmost number (0).
#magicskill 4 0 -- This command sets starting skill in ASTRAL magic. Set the amount by replacing the rightmost number (0).
#magicskill 5 0 -- This command sets starting skill in DEATH magic. Set the amount by replacing the rightmost number (0).
#magicskill 6 0 -- This command sets starting skill in NATURE magic. Set the amount by replacing the rightmost number (0).
#magicskill 7 0 -- This command sets starting skill in BLOOD magic. Set the amount by replacing the rightmost number (0).
#gcost 0 -- This command sets the pretenders starting cost
#startdom 1 -- This command sets the pretenders starting dominion
#pathcost 10 - This command sets the pretenders costs for additional paths.
#end
However, once you are done with testing, I suggest you remove the code.
