if its constituted from chakra preta path can asborb it, that means susanoo/amaterasu are fair game, theyre not some magical techniques that use the power of love, they require chakra to manifest, and with that regard they can be absorbed
and yata mirror/totsuka blade are etheral weapons, not chakra, they cant be absorbed, saw someone say susanoo was made of spirit energy or something in a post, probably stemming from the fact that susanoo can hold etheral weapons, that doesnt make it etheral..:sy:
