I haven't been able to find the answer to this in the docs or the forums or by playing around for several days now and I'm feeling kinda dumb. I'm trying to create an "advanced" zombie. Normally, I would expect to create a base creature (in this case a goblin), add some HD, apply the zombie template and presto. However, I can't figure out the "add some hit dice" part. What am I missing? Please help the dumb kid...
