One of my players uses a homebrew subclass that they found online. I'm trying to add it to DND beyond so they can use the character sheet here, but I can't seem to add the Invocations for them to use on the sheet. Is there a way to add custom invocations? I keep seeing people say to just add them as notes, but that's a bit of a pain I think.

There isn't a way to add custom invocations (yet), but you can add it as a class feature if you want/need.

I was hoping that would work, but it apparently doesn't add the bonuses if it's not set as a pact Boon/ invocation.

What? It will add the bonuses you give it.

Maybe I'm not adding them correctly? I'll have to go back and look it over.
