What’s the best Genshin Childe build?

Childe is a hydro DPS with strong multi-target damage and fast hydro application that enables other members of his team. His burst deals high damage, and, in its ranged form, has low energy requirement, allowing you to use it more frequently. He’s pretty flexible when it comes to team comps, has a uniquely flexible rotation that switches between ranged and melee, and he isn’t constellation reliant, meaning you don’t need more than one copy for him to be a worthy member of your team.

On the other hand, he has lower individual damage output compared to many of the other five-star DPS on offer, and he heavily relies on a well-built team excel. Childe is also pretty tricky when it comes to the technicality of his skills, and you need some practice and dedication to manage his rotations well.

He can play multiple roles on a team depending on his allies, including main DPS, burst DPS, enabler, sub-carry, and even, in some situations, a support – though the latter isn’t widely recommended.

What’s the best Genshin Childe weapon?

As a main DPS, the best Genshin Childe weapon is Polar Star, followed closely by Thundering Pulse and Aqua Simulacra. For burst DPS Childe, your best choice is Aqua Simulacra followed by Thundering Pulse and R5 Mouun’s Moon.

If you’re looking for something a bit more easily accessible, Viridescent Hunt is a good choice for main DPS Childe, and R5 Stringless is great for burst DPS Childe.

Weapon Effect How to obtain
Polar Star Elemental skill and elemental burst damage increases by 12%.

When 1/2/3/4 stacks of Ashen Nightstar are present, increases attack by 10/20/30/48%. Stacks of Ashen Nightstar created by the normal attack, charged attack, elemental skill or elemental burst are counted independently of the others Gacha

What are the best Genshin Childe artifacts?

Generally, the best artifact set for DPS Childe in most situations is Heart of Depth. However, if you don’t have a Genshin Impact’s Bennett to spare for your Childe team, you should combine two Heart of Depth and two Gladiator’s Finale.

For burst DPS Childe, you can combine two  Noblesse Oblige with two Heart of Depth for a great damage boost. For a more in-depth breakdown, check out Kequing Mains’ super detailed guide.

What are Genshin Childe’s talent level up materials?

As with any other character, you can level Genshin Childe’s normal attack, elemental skill, and elemental burst up to level ten. You need the following materials to level each of his talents/skills.

  • Bow centric – normal attack > elemental burst > elemental skill
