I will probably just put all 4 types of Aasimar in the drop-down box, seems the most logical![]()
The DMG Aasimar are strictly worse than the subraces; IMO I think it's fine to replace them with the new version.
I've got Volo's and have been coding up the races there; they don't seem like they'll be too tricky. There's also a handful of beasts that qualify as druid and ranger companions.
Also, I bought it on DM's guild just as a thank you.

EDIT: is there a way to filter out options by sources? With AL requiring PHB + 1 it'd be nice to filter out illegal options.
