Hey!
Noticed in the character creation screen that I cannot attune to the bard instrument: Mac-Fuirmidh Cittern
Checked with the Anstruth Harp.  that one doesnt let me attune either.

The item seems correctly set with an attunement requirement.

Can you post the URL of your character sheet, so we can give a better look at the problem?

Thanks for the collaboration.

You must first click on "Use". That puts the bard instruments into the Active Items. From there, you can attune to the item.

 I got it to work now, misunder stood "use" in the sense that it attunes the item.

Thought it would use it in the sense of taking away charges of the spells
