Fully replace Attribute?

[ctrvl]

Trying to build an aug that completely replaces a natural Attribute - something like an animal brain. I've tried:

perform #traitaugment[attrInt,=,5,""]
perform #traitaugment[attrLog,=,1,""]

But those still add to the character's natural Attributes.

I tried searching through the help from the help tooltip but the page is still under construction. Is there somewhere I can go to see available methods and/or components? I was also going to try something like:

perform hero.child[attrInt].modify[=,5,""]

But I'm pretty sure that's not referencing it properly (HL complains when I try that).

Thanks in advance - love love love this component of HL so far!
