Although, in Genshin impact, you can make any team combination and still ace the overworld content. But when it comes to challenging the spiral abyss, you need to have optimal team compositions. To see whether we can use Gorou with other characters, we need to go over his key use to boost team members' defense from his skill. So, if you're using characters like Noelle or Arataki Itto, you can expect to see an increase in Geo damage bonus and their overall defense. Ultimately, an increase in their defense will enhance their abilities and give players access to their untapped potential. With more constellations, you can even make Noelle, your main damage dealer. I know it may sound astonishing, but having used the main DPS Noelle, I'd say she packs a punch. I like to build healers as DPS for fun. Yet to try main DPS barbara.
