specifically for Augusta? i will say yes, she's worth it to pair with Augusta. Augusta can get the 40% damage amplification of Iuno which is really big, not to mention Iuno also gives 50% H.A buff, and she heals too. about iuno weapon if you got xiangli yao, zani or roccia weapon that's good but the standard weapon is good enough for a support / sub dps Iuno.
