Staff, Rare (Requires Attunement by a Spellcaster)
A staff of living shelf-fungus strung with the singing silk of Cantica, so that it hums faintly when carried. It has 10 charges and regains 1d6 + 4 expended charges when you finish a Long Rest.
Chorus. While holding the staff, you can expend charges to cast one of the following spells (save DC 15): silence (2 charges), gust of wind (2 charges), or shatter as a discordant chord (2 charges). If you expend the last charge, roll a d20. On a 1, the silk falls silent forever and the staff is a mundane length of dry fungus.
