Acrylic

Acrylic is a paint brush once wielded by the roving halfling artist Pollock O'Leary. The paint brush acts as a spell focus for bards granting a +1 spell saves & DC. 

Additionally, the paint brush can conjure any shade of paint without physical materials and gives advantage on performance checks that have used its paint
