The Secret Source Automaton is a new world boss inGenshin Impact. This enemy was introduced with patch 5.1 and drops materials needed to upgrade Xilonen. While it has plenty of health, the boss is not difficult. Additionally, there are specific characters that will make the fight much easier. This guide will teach you where to find the Secret Source Automaton, the best teams, and win the battle.
As mentioned, players must farm this boss fight to levelXilonen inGenshin Impact.40 Original Resin must be used after you defeat the Secret Source Automaton to obtain the rewards. This is standard with other world bosses. When first launching the game after patch 5.1, you will notice the icon for the enemy in Natlan. However, you may be confused about how to reach the world boss.

Where To Find The Configuration Device
Located In A Hidden Cave
To find the Secret Source Automaton, teleport to the Waypoint south of Teticpac Peak. If you head directly south, you will find a makeshift wooden bridge. Underneath is a giant hole in the ground that leads to the boss. Jump down and continue along the passage to the Waypoint before the boss arena.
How To Defeat The Secret Source Automaton
Needed To Upgrade Xilonen
The Secret Source Automaton has three forms of attack. It will fire two rotating beams that slowly collapse and cause an explosion. Next, the boss will shoot three orbital barrages down that track to your character’s location. Finally, the Secret Source Automaton creates two pillars and charges a powerful attack. You must climb on top of each other and destroy the devices. This can only be done with specific Natlan characters. Since everyone got her for free,Kachina inGenshin Impactshould always be on your team for this phase. Xilonen is also able to climb these pillars with her skill.
All New Weapons In Genshin Impact 5.1
Four new weapons are being added to Genshin Impact with Version 5.1. Here is what each of them does and the best characters to use them.
Sun Weion YouTube shows that this world boss can easily be defeated with free-to-play units. He usedTraveler (Geo), Amber, Kachina, and Xiangling in the showcase. This takes advantage of the buff granted by double Geo and Pyro units on the same team. As long as you know the attack patterns of the Secret Source Automaton, the fight is just a matter of depleting its health bar. Some great teams for this fight include:

Kachina
Kazuha
I personally defeated this boss for the first time using Kachina, Kokomi, Rosaria, and Diluc. For this fight, you want to make sure to have constant elemental reactions and burst DPS. While not necessary, this will ensure that the boss fight is over as quickly as possible, freeing up more time to farm materials.
To ensure the boss respawns quickly, teleport away a fair distance or return to the main menu.

While Kachina and Xilonen are made for this boss fight, you can reach the devices by other methods of gaining height. You only have a short time before the Secret Source Automaton launches its charged attack and instantly kills your active character.Kazuha,Zhongli,Albedo,Venti, andWandererinGenshin Impactcan all reach the top of the pillars. Once defeated, you will obtain theGold-Incscribed Secret Source Coresneeded for Xilonen’s Ascension.
Since players only have 200 Original Resin each day, there is a limited-time event that will help out. By completing theTribal Chronicles: Children of Echoesduring the first couple weeks of patch 5.1’s release, players will receive60 Primogems,nine Prithiva Topaz Fragments,six Gold-Incscribed Secret Source Cores,30 Brilliant Chrysanthemum,12 Warrior’s Metal Whistle, and15 Sentry’s Wooden Whistle. All of these are Xilonen’s Ascension materials. While this won’t be enough to get her to a high level, all these significantly reduce the gathering time. Players can gather the last three materials by exploring Natlan inGenshin Impact when your Original Resin is spent for the day.
