A regular Sherlock Holmes in the streets of Inazuma, Genshin Impact's Heizou is a tough nut to crack. He's a sweetheart, but often bored with the mindless tasks of saving people's marriages or finding their dogs. You could give him a real purpose out there on the battlefield with this handy guide to his builds, voice actors, and best teammates.
Heizou may not be the highest-ranking character in anyone's Genshin Impact tier list, but there are things you can do to help him reach his potential. To get his build right, you'll need some Genshin Impact codes - the weapons you roll for in the gacha make or break a unit, after all.
Here's everything in our best Genshin Impact Heizou build:
What's the best Heizou build?
| Rarity | ★★★★ |
| Element | Anemo |
| Weapon type | Catalyst |
| Best weapon | A Thousand Floating Dreams |
| Best artifact set | Viridescent Venerer |
| Main stats | Elemental mastery, attack, crit rate/damage |
What are the best teams for Heizou in Genshin Impact?
Heizou can be used as an Anemo DPS, but there are other units that do the job better. Thus, we recommend using him as part of a Swirl team, or as part of a Dendro-based team as a driver to create more cores. He's good for this because his abilities have a large AoE. We've also included an example of an Anemo-based team in case you prefer to play to Heizou's crit strengths.
Here are some examples of Heizou's best teams:
 Heizou |  Yelan |  Yae Miko |  Shinobu |
| Heizou |  Nahida |  Xingqiu |  Kokomi |
| Heizou |  Xiao |  Faruzan |  Bennett |
What are the best weapons for Heizou?
The best weapon for a swirl-based Heizou is A Thousand Floating Dreams, as it can increase his anemo damage by a considerable amount. This weapon works well if there's double anemo presence on the team, as it also increases elemental mastery for every member of the team with the same element as Heizou, but you should avoid using it with a triple or quadruple anemo setup.
You can also use the Tulaytullah's Remembrance or Lost Prayer to the Sacred Winds if you're using Heizou on an anemo team. These weapons play to Heizou's natural strengths that come with his kit.
- A Thousand Floating Dreams - limited five-star catalyst
- Tulaytullah's Remembrance - five-star
- Lost Prayer to the Sacred Winds - five-star
What are the best artifacts for Heizou?
The best artifact set for Heizou is the Viridescent Venerer set, as it assists with both raw Anemo and Swirl damage.
You could also opt for Noblesse Oblige, which helps with Elemental Mastery, or a two-piece Viridescent Venerer/Gladiator's Finale combination.
These are the best artifact sets for Heizou:
- Viridescent Venerer
- Gladiator's Finale
- Noblesse Oblige
When picking your artifacts, try to prioritize options with the following stats as main and sub-stat options:
- Crit rate and DMG
- Elemental mastery
- Attack
What are Heizou's priority skills?
Heizou's normal attack is his most useful anemo driving ability, so we recommend upgrading this one first if you're using him for swirl or bloom. His crit comes from his elemental skill, so that's the skill to upgrade if you want to use him on an anemo team.
- Normal attack > elemental skill > elemental burst
Who are Heizou's voice actors?
You'll spot Heizou's VAs everywhere! His English voice actor Kieran Regan is in Cookie Run Kingdom, Pokémon Horizons, and Fortnite. Lin Jing is in HSR and can be heard in Honor of Kings, too. Heizou's Japanese voice is brought to you by extremely decorated voice actor Iguchi Yuuichi, who's appeared in everything from JoJo's Bizarre Adventure to Xenoblade, and his Korean voice actor features in radio dramas and games like Digimon. Cool!
