The Aetherium Wars limited time event inHonkai: Star Railunfolds much like any regular quest, meaning there is a lot to do if you want to successfully complete it and earn every reward. This includes challenging all the unique Victory Zones, of course.
True to the Trailblazer name, you must first obtain three Mastery Marks in each of the previous Victory Zones so the Great Mine Victory Zone becomes available to you. There are more Aether Spirits waiting for you in these caverns, as well as more treasure and different puzzle challenges. You’re one step away from the championship now, Aether Player!

How To Begin Clash! Great Mine!
This quest beginsoutside the Goethe Hotel, where you must speak to March 7th to begin. You will promptly bedirected to the Great Mine: Entrance area.
You canfast travelto the location usingthe Space Anchor by Natasha’s Clinic,which is a mere few steps away from the entrance to the Great Mine.

Once you arrive there,your player terminal will automatically pop upfollowing a short conversation with March, and you will beprompted to select the Great Mine Victory Zoneand enter it through the same interface as every other Victory Zone before it.
The first people to greet you there will be the so-called “Topaz Support Squad,” theIPC workers that have been consistently trying to reclaim your Warp Trotter Aether Spirit from youthroughout the entire quest line.

However,you will not fight them this time, as your confrontation will promptly becut short by Topaz herself. She is not there to challenge the Victory Zone, butshe will give you a simple but very important directionabout how it all works in there.
How To Clear The Detonation Locations
Follow along the path a short distanceand speak to the little robot, an Automaton Beetle model, who isserving as the Victory Zone’s guide.
It will explain to you thatthis Victory Zone consists on remotely operating Automaton Spidersto sneak up on the IPC members scattered across the different Detonation Locations.Your goal is to blow them up, to put it simply.

You will have tooperate the Automaton Spiders carefully, attempting not to alert any of the IPC targets as you approach. Otherwise, the Automaton Spider will take damage, andthe challenge will abruptly end.
Additionally, youmay only use the Automaton Spider onceper Detonation Location, so you musttime each explosion correctly.

The Victory Zone guide willfollow along throughout the entire challenge, as it will be the point of access for you to switch to Automatonremote control mode.
Whenever you enter a Detonation Zone, the guide will assess the presence of the IPC targets, and give you clearance to operate the Automaton Spider.

You will get tocomplete a simple versionof the mechanism before the first challenge, as usual. You will have todetonate a lone IPC employeeto get a feel ofhow to operate the Automaton Spiderand what you have to do.
Detonation Location One
After getting past that IPC employee and the tutorial,you will arrive at an open areawhere you will see a handful of tents.A Silvermane Soldier Aether Spiritcan be seen on patrol here, and there is a challenger, with a team composed oftwo Silvermane Canonneers and two IPC Grunt: Security Personnel, by one of the tents.
Clear this area to easilygain access to a Basic Treasurethat is by one of the tents.Then continue along the path Westto arrive at the first Detonation Location.

This area has two IPC workers standing guard. One of them is static by a mine cart, while the other one paces back and forthalong a small distance on one side of the same mine cart.
To clear this challenge, you mustwait until the pacing IPC worker turns aroundand follow them until theAutomaton Spider’s explosion AoE has reached the static IPC workeras well. Then trigger the explosion, and you’re done.
Detonation Location Two
Continue forward along the pathand you will run into a static Automaton Spider Aether Spirit you must defeat to keep advancing. Then, as youarrive at a Space Anchor, you willenter the second Detonation Location.
There aretwo IPC employees in this area. Once again,one will be static while the other one will pace a short distancenear the first. The complicated part in this challenge is thatthe Static IPC employee will be facing your wayand is thus easily alerted.
Wait until the pacing IPC employee is facing away from youand advance forward while inan outward arcto put distance between you and the IPC employees.
Once you have crossed, take a right, making sure to get closer to the employees through thenarrow opening you will find by some crates; this will put youout of the immediate range of the static IPC employee. Then, advance as the one that’s pacing isin a position where they won’t see you, and once your AoE reaches both, trigger the detonation.
Detonation Location Three
Fight and defeat the Aether Spirit that isjust before the ramp where you will need to climb to continue.
Make sure youdon’t miss the Basic Treasure you will findrigth under a door at the top end of the ramp.
You will continue forward and onto a bridgewhere you will facethree challengers back to back. The first has two Automaton Spiders and two Imaginary Weavers in his team. The second, two Vagrants and two Imaginary Weavers. The last has two Silvermane Soldiers and an Automaton Grizzly.
Defeating the last one will grantaccess to a Precious Treasure, and you will be free tocontinue forward.
Continuing throughthe road with the train tracks will bring you forward along in the challenge, while taking the path that splits off towardsthe left will bring you to a Vagrant Aether Spirit and a Basic Treasure.
Walk forward along the train tracksa little and you will arrive at thethird Detonation Location.
This time there will bethree IPC employees; two of them static, and anotherone pacing back and forth in a small area. To down all of them at once, you will proceed in a similar wayas you did in the former puzzle.
Wait until the IPC employee closest to you is leaning on their weaponor they will spot you more quickly. Then, use thesmall path to their left(towards your right) towalk behind them without being spotted. Approach themfrom the back carefully and activate the detonationonce they are all within range.
Detonation Location Four
Continue forward along the tracks. There will be anotherAutomaton Spider in a cornerfor you to fight. It is really close to thefourth and final Detonation Location.
Full disclosure, this location ismore like a part of the story than it is a challenge.
You will load an Automaton Spider into a mining cart and thenall you have to do is interact with it to push it forward, and March 7th willcue you to trigger the explosion to down the IPC employeesthat were blocking your way.
As you walk along the train tracks tomove forward once more, you can take aright into another path to defeat a Vagrant Aether Spiritand claim thefinal Basic Treasure in the Victory Zone. You will shortly arrive at the final destination ifyou return to the tracks and move forward.
How To Defeat Giovanni
The last member of the IPCwill flee after a short exchange. Then, the little robot guide willtransfer the coordinates of the Championship Contenderfor that Victory Zone to you. you’re able to easily reach the spot where he’s waiting for you byfast traveling to the Match Point 1.
The Championship Contender for the Great Mine Victory Zoneis none other than Giovanni di Giorgio, themysterious Masked Fool that has hovered over youfor most of your journey as an Aether Player.To earn the Mastery Mark, and get the answer to some burning questions,you will have to defeat him.
Giovanni’s team is composed ofan Everwinter Shadewalker, a Frigid Prowler, an Automaton Spider, and a Silvermane Soldier. His boss fight is not particularly difficult, provided you have kept your Aether Spirits well leveled throughout. You can make the most of your team by doing some or all of the following:
Defeating Giovanni will conclude the questand you may freely exit. However,completing all the Victory Zone objectiveswill, as usual, require that youaccess the Blocked Off Area and collect the Aether Spirit that dwells within it. In this case, it’s a Frigid Prowler. That’s an Aether Spirit youwill certainly want to have.
