I wanted to share some of the projects I've been working on for my own D&D games with the community, all of these are free and open to everyone to use and I will be updating this post whenever I make new conversions. Feel free to make requests and please leave a comment, I tend to work better with direction!

 Enjoy and let me know what you think! 🙂

I added an edit log so those of you that follow the thread can see what changes have been added to the list(s)

Races

Classes

Feats

 Spells

 Weapons 

 Items

 Edit Log (beginning with 9/5/2022)

After much deliberation we've come up with a few suggestions that you're welcome to use however you wish. I figure the Crests from Three Houses are a no brainer for feats that could possibly connect to the relic weapons, you probably already thought of that though. I originally figured a Fighter subclass could be neat for Edelgard's emperor class with a possible fighting style to accompany it, I was gonna leave it at that but a friend of mine brought to our attention that she also knows a lot of spells that she could never use so you could possibly make it an armored casting class of sorts if you're willing to take some liberties. I saw that you used constitution for spell casting before and perhaps that could be the spell casting ability for the sub class (or even class if you're feeling risky). Another friend mentioned a Barbarian Dimitri sub class that I can see being interesting. One that we all agreed on being cool to see you tackle would be an Ike based Fighter sub class or class, be it based on PoR, RD, Fates, or a combination of them all it'd be exciting to see either way. I was gonna suggest Holy Blood feats or Branded as a race but there isn't much to go on for those so it might be difficult to make anything out of that but you're welcome to try. I would suggest more but I don't wanna be that guy (I already feel like that by typing all of this out). If you desire to use any of these ideas I'd be incredibly grateful but either way I look forward to seeing what you come up with in the future. :)

Hey, Thanks for taking the time to comment!

I agree that the crests would make great targets for feats. I think that's a great project to tackle. I will likely be making them in a way that they are unrelated to the relics, but the relics have effects that require/reference the feats, if a wielder does or doesn't have it. Classes are big projects so that might be a while, but I've added it to the list of potential conversions!
