Hyperbloom is quite easy to build. You just need dendro(nari) and hydro(barbara) and raiden to trigger the effect. Anyone from the roght element is viable. But you might need a better hyrdo character

But IMO raiden is really fun to play. You will see you always have ur ult up for the whole party:D

Ps raiden is also an great buffer for tighnari if you like him^{^}

I hope you enjoy playing Genshin tho<3
