I have created a custom feat "Befriending Goblins" which unfortunately is only apply 3/6 modifiers when applying to a character.

The ability should allow the player to have advantage on insight, persuasion, perception & history, whilst having advantage on all attack rolls!

The current format currently only allows the top 3 modifiers to actually be applied, with insight, persuasion & perseption working as intendended 

Any support on this issue would be beneficial as looking to have this ready for my players in 2 days time.

Thanks DnDBeyond community

You must not have re-saved the feat after adding the Modifier for history. As to the advantage on attacks it won’t ever show those, the character sheet isn’t capable of displaying that.

Perfect thank you, after about 10 min, DnDBeyond finally updated with the history modifier! 

Wasn't aware on the attack rolls, thank you for clarifying! So excited to add this custom feat in so thank you for that!

Happy to help.
