Finding Childe's Boss Location 
Prerequisites
1.Ensure you are at least Adventure Rank 30 to participate in the weekly boss fights, including Childe's.
Travel to Liyue
2.If you are not in Liyue, teleport to any waypoint in Liyue, preferably those closer to Liyue Harbor for easier navigation.
Navigate to the Golden House
3.The Golden House is where you'll battle Childe. This location is south of Liyue Harbor, near the Chasm but not within it.
4.From Liyue Harbor, head south past the Stone Gate. You might need to pass through or near Qingce Village but keep heading southward until you see a grand structure, which is the Golden House.
Accessing the Boss Fight
5.Domain Entrance: Once you're in the vicinity of Taishan Mansion, look for the distinctive domain entrance. This will be marked on your map with a special icon indicating a Trounce Domain. The entrance is typically surrounded by a unique structure or atmospheric effects.
6.Weekly Challenge: Childe's boss fight will be listed as "The Unreachable Star Challenge" in the domain menu. You can access this directly from the domain entrance or through the map menu by selecting the domain.
Best Team Composition

•Pyro DPS: Characters like Diluc or Hu Tao can vaporize Childe’s Hydro slashes, dealing significant damage.
•Cryo DPS: Ganyu can keep distance while dealing Cryo damage, useful in both phases.
Sub-DPS/Support
•Xingqiu or Xiangling: Xingqiu's rain swords can help with off-field Hydro application, while Xiangling's Pyronado deals continuous Pyro damage.
•Fischl for continuous Electro damage, helping with reactions like Overload or Electro-Charged.
Healers/Shielders
•Bennett for healing and Pyro resonance.
•Zhongli for shields to mitigate damage from Childe’s slashes and arrows.
Utility
•Sucrose or Venti for Anemo support, though Venti might not lift Childe, Sucrose can still swirl elements.
Understanding Childe’s Mechanics
•By understanding Childe’s mechanics and employing these strategies, you'll enhance your chances of defeating him efficiently and securing the valuable rewards he offers, like the Talent Books and
•Phase 1: Hydro Melee Form: Childe uses his Hydro-infused daggers for close combat, characterized by swift, sweeping attacks.
•Phase 2: Electro Ranged Form : Transitions to using a bow, firing Electro arrows with wide AoE effects. He also employs Hydro shields and attacks.
•Phase 3: Combination Form: After further reducing his health, Childe combines both Hydro and Electro, becoming more aggressive with both melee and ranged attacks.
Strategies for Defeating Childe
Elemental Reactions
•Vaporize: Use Pyro against his Hydro form to deal increased damage.
•Electro-Charged: Effective in his melee phase, but be cautious in his ranged form due to his Electro resistance.
Dodge and Positioning
•Melee Phase: Dodge or use i-frames from skills to avoid his slashes. His attacks are predictable but swift.
•Ranged Phase: Use the pillars for cover. His arrow volleys can be dodged with well-timed rolls or by using the environment.
Focus Damage During Vulnerable Moments
•Melee Phase: Deal as much damage as possible when Childe is about to switch phases. His melee phase vulnerability windows are key.
•Ranged Phase: Use ranged attacks or characters with strong AoE to deal with both Childe and his Hydro blades.
Healing and Shield Management
•Ensure your healer or shielder is ready. Childe’s attacks, especially the Electro arrows, can quickly deplete health.
Energy Generation
•Characters like Fischl or Diona can generate particles, helping in maintaining Elemental Burst uptime.
Childe’s Reward Drops
Here are the potential rewards you can obtain from defeating Childe:
•Primogems: You receive Primogems upon defeating Childe for the first time each week.
•Mora: The in-game currency.
•Hero's Wit: Used for leveling up character talents.
•Local Specialties: Such as Cecilia or Windwheel Aster.
•Common Crystals: Like Luminous Sands from Mondstadt or Liyue, depending on the domain's theme.
•Boss Materials: Specifically, Childe drops materials used for character ascension and talent upgrades:
Shrimp Meat (or its enhanced versions like Crab Meat)
Dead Ley Line Leaves
Tusk of Monoceros Caeli (or its enhanced versions like Tusk of Monoceros Caeli Fragment, Shard, and Chunk)
Talent Books like "The Meaning of Aeons" or "Teachings of Gold"
These materials are essential for ascending and enhancing characters like Childe himself, Xingqiu, and others who require Hydro-related materials.
•Artifact Enhancement Materials: Such as Enhancer, Prism, or even a chance at a 5-star artifact.
Note: The exact drops can vary, but you are guaranteed certain items like the boss-specific materials (e.g., Tusk of Monoceros Caeli) and have chances at others. Remember, like all weekly bosses, Childe can only be challenged once a week per account, resetting every Monday at 4:00 AM (server time). Note: For the most efficient farming, focus on defeating Childe at least once a week. Using characters that can quickly and safely defeat him will help maximize your weekly rewards. Consider using characters with Hydro resistance or strong Hydro damage dealers to make the fight more manageable. |
Tips for Winning this Boss Fight! 
•DPS Rotation: Use characters' elemental bursts in a way that maximizes their uptime, especially during Childe’s vulnerable moments.
•Environmental Advantage: Utilize the layout of the Golden House for cover against his arrows. Roll through his attacks or hide behind the pillars.
•Artifact Optimization: Prioritize artifacts that increase your main DPS’s CRIT Rate/DMG or Elemental Mastery for reactions. For supports, focus on Energy Recharge or HP for healers.
•Stance Timing: Pay attention to when Childe is about to change forms. This can be an excellent time to burst him down or prepare your strategy for his next phase.
•Mark of the Harbinger: When Childe marks you with his vision, be prepared to either cleanse it with Bennett's burst or endure the subsequent attack, which can be a good time to use a shield.
•Stay Mobile: Childe's attacks, especially in his final form, cover a wide area. Constant movement can often save you from a lot of damage.
•Cooldown Management: Try to have your Elemental Skills and Bursts ready for when Childe is most vulnerable or when you need to break his momentum.
•Use Characters’ Strengths: Characters like Zhongli can provide continuous uptime with his shield, allowing for more aggressive play without fear of interruption.
•Adapt to Phases: Switch your strategy when Childe changes phases. Keep ranged characters like Ganyu or use Sucrose to swirl elements and disrupt his Hydro blades.
