I just got a Canaith Mandolin while being in Avernus and there is something in the description that I would like to clarify.
If I understand well, in Avernus, there isn't any dawn. No sunrise.
Does that mean that if I stay in Avernus I won't be able to recharge my Canaith Mandolin spells ?
The description says
A bard playing a Canaith mandolin could invoke the spells [...] each once a day, until the instrument recharged its magic at the next dawn.
