Hey folks. I've tried twice now to dive into the homebrew creator, and left frustrated that I can't figure out how to make a Custom Lineage from Tasha's. The homebrew creator as a whole has been something I can't seem to sort out. Guess I'm rolling low on my investigation checks. Or would it be a tool proficiency? 

Would any kind, knowledgeable souls be up for making a short tutorial video on how to do it? 

If you have a subscription, this person already did it you can just add theirs to your collection: https://www.dndbeyond.com/forums/dungeons-dragons-discussion/homebrew-house-rules/88613-custom-lineage-made-in-homebrew-for-everyones-use?comment=1

PS- This is neither a Bug, nor a support issue. There’s a specific “Homebrew & House Rules” forum specifically for questions like this. 

No subscription :/

Then PM them, or leave a comment on their homebrew and aske them how they did it. It really shouldn’t be that hard to do. It looks straightforward enough, but it would take me the time to build it myself to check to see if I correctly remembered what I think is correct. They already did it, so they can just tell you how.
