Mizuki's Artifacts: These are better!

It's really great for farming currency. With 2pc Elemental Mastery + 2pc Elemental Mastery. That's all you need to equip. Honestly, for those who have played Genshin for a while, you can use it immediately without needing to farm separately... It's a legendary currency farming character. For the Crimson Witch set, the 2pc effect is ATK, so I think stacking Elemental Mastery is stronger.
