Theater Mechanicus Event Guide

Theater Mechanicus is an event that has a tower defense mechanic. The objective is to eliminate multiple waves of enemies before they reach and inflict damage to the Ley Line Monolith.

Talk to Ruijin

To start the event, Travelers must visit Ruijin, in Liyue Harbor.

Select Stages and Difficulty

Before starting a stage, you can select different kinds of challenges, and adjust the difficulty level. More challenges and higher difficulty allows you to earn more Veneficus Sigils.

Stage	Difficulty & Mechanici Level Limit	Max Sigils	How to Unlock

Set up Your Defenses

Before starting the tower defense challenge, you must set up your defenses first during the Construction phase. Travelers can place mechanici on designated points in the map, which will help you defend your objective.

Reconstruct or Dismantle Mechanici

In-between phases, you can reconstruct Mechanici, or dismantle then to return some Veneficus Sigils.

Stop the Enemy

Once you have set your defenses up, it's time to stop enemies from reaching the monolith.

Monsters will not attack the player, and characters cannot deal damage to monsters. This is why Mechanicus placement is key to finishing each stage.

Special Features

Enlarge

Travelers can also use different special features that give you another way of dealing damage to monsters. These have a cooldown timer after being used, so timing is crucial.

Depending on the challenge level, there's only a limited number of monsters that can escape. Exceeding that number will cause Travelers to fail the current challenge.

Earn Veneficus Sigils

Completing each stage allows Travelers to earn Veneficus Sigils.

Upgrade Mechanici

These can be used to upgrade your Mechanici, improving it's DMG, Range, or ATK speed.

Mystic Art

Completing each wave allows you to choose one Mystic Art for the current stage. These have effects such as allowing you to construct more Mechanici, increase wave difficulty, buff Mechanici, or earn more Veneficus Sigils. Whichever you choose will help add more challenges or give you a defensive advantage.

Unlock More Stages through Festive Fever

As you progress through Festive Fever, you will unlock new Theater Mechanicus Stages. This means new Mechanici, higher upgrade levels, and increased difficulty levels. You will also unlock more challenges, which means more Peace Talismans!

Can be played Solo or Co-op

Theater Mechanicus is another event that will surely provide a new challenge for Travelers. You can play the event solo, or play with a friend. Up to two Travelers can play the event together in Co-op!
