Runes cannot be added to sceptres

Wands seem to work fine but i'm currently unable to add any runes to a sceptre.

Am i missing something and this is by design?

Can't seem to socket runes into sceptres either. Sockets must be cosmetic for the time being.

Same, seems to be bugged.

The socket is for talismans. They might need to update the artificer's orb description*.

Having it just for Tailsmans seems counterintuitive. The fact that you can add a socket as early as Act one but don't encounter Tailsmans till endgame is bad design. I suspect that they forgot to update runes to include sceptres and will update eventually, hopefully.
