You can add the Bane Rune to a weapon, but there is no method to pick the monster type and the weapon doesn’t show the bonus, or am I missing something?…
I checked the data for the Bane Rune and it appears that we don’t currently have the ability to specify creature type as part of it. The workaround would be to add it as a note on the weapon. When you say that the weapon doesn’t show the bonus do you mean that it’s not giving the option to add the additional 1d6 damage? Because that definitely looks like it should be set up.
I think I see the extra damage listed. Thanks.
