I was interested in the same idea. I found one more spot that needs to be edited and I think it ties to the trait box
add to characters/description.gd about line 169 or so where "augmentstr" is located
if person.mods.has('augmentmaf'):
text += "[color=#B05DB0]Through magical modification, the potential of $his magical affinity has increased.[/color]\n"
if person.mods.has('augmentend'):
text += "[color=#B05DB0]Through magical modification, the potential of $his endurance has increased.[/color]\n"
