Noblesse Oblige is one of the best universal sets that work on almost every Support in Genshin Impact. It’s so smooth and simple to use to the point. If there’s a buffer, put Noblesse, and it’s a better buffer now. If there’s a healer, add Noblesse, and it’s a healer/buffer now. If there’s a shielder, well, you know the rest. Just add Noblesse to any unit and make a Support out of them.
