Beidou is a pirate with a claymore, she literally killed a sea monster with no vision, yet she’s not muscular at all. This isn’t what the lord wanted, she deserves muscle. The average claymore ran about 140 cm (55 in) in overall length, with a 33 cm (13 in) grip, 107 cm (42 in) blade, and a weight of approximately 5.5 lb (2.5 kg). The favonius great sword is the most accurately depicted claymore in genshin. Beidou is seen with much larger claymores, usually 2x to 3x the width of the favonius sword. If the favonius great sword is around 5.5 lb (2.5kg) and we multiply that number by 2-3 we get 11-16.5 lb (5.0-7.5 kg).
