Boudewijn's Bounteous Inspiration

When you cast this spell, and as a bonus action on each of your turns before the spell ends, you can choose two creatures as the target of your Bardic Inspiration feature. You expend one use of the feature per target, as normal. These Bardic Inspiration dice last for as long as you concentrate on the spell, or 10 minutes, whichever is longer. In addition, while the spell is active, creatures treat a 1 on a roll of your Bardic Inspiration die as a 2.
