Keqing is a standard banner 5*, who uses a sword and an electro vision. She is usually utilized as a DPS, but also works well in exploration teams. This webpage will go over her kit, constellations, playstyle, best artifact builds, best in-slot weapons, and teams.
Keqing's kit relies mostly on her raw DMG output, but can also be utilized when off-field application units are on the same team. For her normal attack, she does a 5-combo chain that increases as she continues attacking, like most characters. Her charged attacks deal a decent amount of damage, but some of her best utility lies in her electro infusion. Similar to Raiden Shogun, her E-skill infuses her weapon with electro. Unlike the Shogun, though, she cannot do off-field application. Her E also deals AoE electro DMG if a charged attack or Stellar Restoration is used. Her second passive boosts her crit rate and her energy recharge while she is using her E. Finally, her burst deals massive amounts of AoE electro DMG, similar to Kujou Sara.
