One of these new materials is the Marionette Core.
Where can players find Marionette Cores, and what good are they?
Genshin Impact Marionette Cores
Once players reach Act III of the Midsummer Island Adventure, they can challenge the Maguu Kenki boss.
A construct seemingly of Inazuman origin, this new boss provides a tricky melee battle, blocking many ranged attacks with its Mask Parry.
Once the Maguu Kenki is defeated, players can spend resin to earn rewards, just like any other boss in the game.
One of these rewards is Marionette Cores.
As of right now, defeating the Maguu Kenki is the only way to obtain Marionette Cores.
While Marionette Cores are currently only available in the Golden Apple Archipelago, miHoYo has announced that the boss will be available to fight in Inazuma once Genshin Impact 2.0 arrives.
What Are Marionette Cores Good For?
So what can Genshin Impact players use Marionette Cores for?
There is currently nothing in the Genshin Impact that requires Marionette Cores.
Thankfully, this means players can stockpile them for when they actually have a use.
The Golden Apple Archipelago
Genshin Impact 1.6 introduced the Golden Apple Archipelago, an entirely new location where the Midsummer Island Adventure takes place.
The islands in this location are ripe with treasure chests, quests, and materials to collect, including Marionette Cores.
Players should gather as many of the unique materials from the Archipelago as possible, as the entire location will go away once Genshin Impact 1.7 launches.
miHoYo has confirmed that the Golden Apple Archipelago will no longer be accessible after Genshin Impact 1.6, though it may come back for a future event down the road.
