Re: OOC IV
Alisandra is going to start practicing the flute; her previous player(s) chose bagpipes, horn, and drum for her instrument proficiencies, so I will need to train. Do you use the Xanathar's rules (10 weeks/50 days' effort and 250 gp) or the PH rules (250 days, 1 gp per day)? Is it easier/less time consuming/cheaper for me, since I'm a bard and already musically trained; bagpipes are a finger-keyed instrument like the flute [although in a very different register and the breath management is certainly different]) to suss it out? Can I let a proficiency "expire," i.e., from lack of practice, and swap in flute? Alisandra doesn't OWN bagpipes and probably hasn't done the piper thing since she left the mercenary company.
Guidance/ruling appreciated, thanks!
