Raising Bennett’s Constellation level to C6 in Genshin Impact can be a bit controversial. The game by HoYoverse offers a wide roster of characters that can be made stronger through Constellation upgrades – these can be obtained when players get the same character from gacha banners or events after they have already unlocked the playable hero. Despite being a free-to-play character, the Mondstadtian is versatile and can be used as a healer, an elemental enabler, and even a sub-DPS for some. His set of skills is very particular, and no other characters match him. Bennett's usefulness even tends to surpass many of his 5-star counterparts.
