Communal Flute

Musical instrument (flute), rare (requires attunement by a bard)

The communal flute can be used as a spellcasting focus by a bard. In addition, a bard can use the flute to cast speak with dead without using a spell slot. To do so, the bard must play the flute over the corpse for 10 minutes, after which the spell takes effect. The bard must complete a long rest before using the flute to cast speak with dead again.
