Augment Critical

[Zorikune]

Hello everyone, new to the forums here, but not to the program or its editor.

I have a question about implementing this into hero lab. I have been putting in druid animal companions like dinosaurs, dire animals, and other companions, and the one I'm currently having a bit of trouble is the dire animal, rhinocerous from Fiend Folio as I cannot figure out how to change the crit range and multiplier on the natural weapon. Is there a way to change the crit range and multiplier on the natural weapon, or a script that can be put into the Augment Critical that would do so. I have already made the Augment Critical into the special to show what it does now I just have to figure this out. Any help would be appreciated.
