Genshin Impact is never without a big event. Whether it’s to tide us over until the next big update or offer some insight into its ever-expanding lore, there’s always something to do.
The Energy Amplifier event doesn’t offer a ton of reason to dive into the story of the game, but it does bring with it plenty of challenges, such as true RPG team-building and the potential for a silly amount of free Primogems. Here’s how to complete the Energy Amplifier event in Genshin Impact, from how to get a free four-star character and loads of free pulls, to where to find all the Mutation Stones that can make the event much harder than it needs to be.
What is Energy Amplifier? The Genshin Impact 1.5 event explained
The Genshin Impact Energy Amplifier event looks more complicated than it really is. Taking cues from past events like Unreconciled Stars and Hypostatic Symphony, this one has you collect Fractured Fruit Fragments and Shards from mob camps buffed by nearby Mutation Stones. Each of these Fractured Fruit pieces then unlock equippable buffs you can use to challenge new domains for additional rewards.
As you stack difficulty multipliers onto the final event domain — Twisted Realm — to increase the points you gain across its four floors, better management of your available buffs becomes essential. Find the perfect loadout for your team and you’ll accumulate enough of the event currency to buy anything from Upgrade Materials to Primogems from the event shop. The event starts automatically with the Mr. Melancholy quest. Just head into Liyue and talk to the researcher to kick things off.
Is the Energy Amplifier event co-op/multiplayer?
With so many moving parts throughout this event, it’s hard to tell whether it’s built with co-op in mind. Some of it clearly is: you can have separate Fractured Fruit buff loadouts for single player and co-op runs, but the rest is a little unclear.
Turns out, though, virtually every part of the event can be completed with friends. The three domains split across Acts I-III can be completed in a group. You just have to have your buddies join your world beforehand. Then, when you head into the Character Select screen of each domain, you’ll be prompted to open it up to the others in your world.
As for the Mutation Stone camp clears listed below, though you’re free to clear these with whoever happens to be on your world, it’ll only clear in your world. They’ll have to go back and clear it on their own world to collect their own rewards.
How to get Diona for free
Whichever side of the event fence you’re on, there’s something to gain from it: primarily a free Diona to add to your character roster. Unlike the Lantern Rite Festival event, which took a lot of time and effort to get the free Liyue character choice out of, this event can net you a free Diona in 20 or so minutes right at the start of the event. Here’s how to do it.
To get a free Diona during the Energy Amplifier event, you have to “invite” her through the Initiation event screen. Doing so costs 1,000 Fractured Fruit Data, which is the simple event currency you get for doing just about any of the event tasks listed below.
By the time you’ve completed the Act I stage (and the short Domain at the end) you’ll have more than enough of the stuff needed to invite Diona into your squad. Just open up the event screen again and hit the corresponding button where it says “Diona” to make the trade and get a free four-star character before the event ends.
Fractured Fruit Fragments: All Mutation Stone locations
As your first task during the Energy Amplifier event, you’ll be sent on a trip around Teyvat to recover Fractured Fruit Fragments from specific places of interest. These crystals — which you’ll rely on to help clear the dungeons later in the event — are all guarded by monsters buffed insurmountably by nearby rocks called Mutation Stones. Attempt to fight the camps without destroying the Mutation Stones, and even a regular hilichurl archer has the potential to one-shot your best character.
These places of interest make up three acts, with each act having nine enemy camps split between three locations to hit up and clear out. Open up the Event screen, tap into the Act you want to progress through, and then the specific place of interest. Finally, hit Navigate on the first entry and you’ll be directed to the other two in sequence as you collect the Fruit Fragment.
Though the camps are pinpointed on the map, the Mutation Stones that buff them are not. Below are all the Mutation Stone locations, so that you’re never forced to fight these ferocious monsters at their buffed-up best. Sneak up on the stones without alerting the nearby enemies and you’ll have a much quicker and easier time clearing the camps, collecting the Fragmented Fruits, and earning some free Primogems, event currency, and other goodies.

Vishap’s Rest: Act I Domain Best Characters
This first run is nothing special. Despite the Electro/Cryo recommendation, neither are actually necessary. Just bring a Geo character if possible to make the last fight a little easier.
Hop across the waterway, beat up the slimes, snipe the two archers either side of the door and it’ll open up, revealing another pack of monsters for you to dispatch. This isn’t too dissimilar to a regular hilichurl camp. Just take them out, then use the wooden boards along the wall to climb up and into the area to the left. Activate the switch and ride the air currents to the final arena.
Here, Geovishaps Hatchlings will challenge you to a fight. Use shields (if available) to knock them over and burst them down. Finally, a standard Geovishap will come along with a smaller buddy. Not much changes here, but keep some stamina in reserve to dodge some of its heavier attacks. Clear the fight and you’ll win some free Primogems.

Where Shadows Writhe: Act II Domain Best Characters
This one can be quite difficult. It’s a time attack challenge with a bunch of different elements in play. To make matters worse, the arena in each of the three rooms will be surrounded by an electrical field that will strike your characters for heavy damage should they venture out too far. You can heal through it with Elemental Bursts from characters like Qiqi, Bennett, and Diona, but you’re better off finding a way to ensure the enemies stay within reach.
The first room is simple enough: Just a few slimes and Hilichurls. But it’s the second room, guarded by Fatui enemies like Sharpshooters and Agents, that can cause a problem if you don’t bring the elements needed to break their powerful shields.
Electro and Water is recommended for a reason. Characters like Fischl, Xingqui, and Lisa can work well on a budget, but Mona, Tartaglia, and Keqing are the five-star characters you’ll likely want to bring if you have them. Venti (or a weapon like The Viridescent Hunt) can help keep enemies pinned to the middle of the arena so that you don’t have to deal with the outer electrical field. Just make sure you bring a ranged character to deal with stragglers or a decent healer or shielder to ensure melee brawlers can fight on the outer edge of the arena without dying to the lightning.
Act III: All Mutation Stone Locations
