This event is unlike anything Honkai: Star Rail has seen so far and it has lots of components to it, so participating might seem like a daunting prospect at first. Luckily, the event is extremely easy to follow once you understand how it works, plus you’ll earn some incredible rewards as you work through it.

Here’s what you need to know about the Aetherium Wars event to find success in it.

What is Aetherium Wars in Honkai: Star Rail?

The Aetherium Wars event is a Pokémon-style tournament where you can collect Aether Spirits, which take the form of foes you commonly battle throughout Honkai: Star Rail and use them in battle to try and claim victory against other competitors.

How to unlock Aetherium Wars in Honkai: Star Rail

You’ll have to complete a prerequisite quest before you can participate in the special Aetherium Wars event. This is the Trailblaze Continuance “Future Market (II)” quest, which will allow you to meet Topaz and Numby before leading you into the official Aetherium Wars event.

There’s a pretty long and challenging fight near the end of this quest, so be sure to bring a very strong healer or shielder into the battle or you’ll likely struggle to pass it. Once you’ve finished the quest, you’ll obtain the “Let’s Go! Aetherium Wars!” quest, which will officially initiate the event.

How to fight in Aetherium Wars in Honkai: Star Rail

You can only battle in Aetherium Wars by using the Aether Spirits you collect. Combat looks almost identical to how it usually does outside of the event except you can only use the spirits you collect, which are usually your opponents, instead of your well-built characters.

There are three different types of Aether Spirits you can add to your team, which are:

  • Humanoid
  • Mechanical
  • Aberrant

Each of the three Aether Spirit types excels at dealing damage against another type and is extremely weak against the other one. You can think of this process as being quite similar to rock, paper, scissors as each spirit type has both an excellent strength and a brutal weakness.

To find success in combat, you’ll want to switch up your team before heading into any battle to ensure you have mostly Aether Spirits that with counteract the Aether Spirit type of whatever foe you’re about to battle. You can tell what type any spirit is by looking at the logo next to their name.
