You edit the script nw_s0_summon, to put in the ResRef of the creatures you have just made. In making the creatures, below is a list of scripts and events those scripts go on. Don't worry about the fact that nw_ch_aca doesn't exist anymore , the summoned works fine. Once you get the first summoned working, go to the scripts tab, save script set as, pick an appropriate name (like "summoned monster" and save it. Now when you make more , you can just load it up and never have to type all this stuff in again. Oh yea.
