I’m unsure if this is a question to ask you, but how viable is balsa wood for a quarterstaff? And how viable is a quarterstaff in combat itself?
Balsa’s a bit fragile for a staff. Usually, when you want a light weight staff, the material of choice is bamboo. But, most durable woods can do the job. Pine is nice for this. Oak is the traditional choice for a quarterstaff.
Staves of any variety are very viable, this includes the quarterstaff. They’re easy to train people on, simple to use, and they can absolutely mess someone up. Even in the hands of someone who only kinda knows what they’re doing, they’re a good weapon.
