I'm relatively new to D&D so I find that I rely on the offline Character Builder quite a bit in order to make sure that I'm not fudging any numbers. It seems to work really well overall, but I ran into a problem when I wanted to use a musical instrument (Fochlucan bandore) as an implement for my Bard. I can purchase the item, but I can't equip it, and on my character sheet it isn't listed on the power cards.
Does anyone know why this might be? Is this a bug or am I doing something wrong?
