Want to know how to beat Genshin Impact’s Theater Mechanicus? Liyue’s Lantern Rite festival introduced Ruijin’s tabletop game, Theater Mechanicus, a tower defence minigame in which players could earn Peace Talismans and trade them in for various rewards.

In the Genshin Impact 2.0 special program, Mihoyo revealed that Theater Mechanicus will make a return in the next update. The announcement reveals that ‘thanks to the efforts of the Theater Mechanicus Representative Komakata, everyone’s favourite game from Liyue is finally available in Inazuma’. As the original Theater Mechanicus was themed around Liyue’s Lantern Rite festival, we expect several aspects of the game to change and adapt for an Inazuman audience.

The trailer doesn’t reveal much – all we know is the game will be expanded upon with ‘more unique content’. From a screenshot, we can see that we are able to draw Wondrous Sticks, which appear to be ‘Fortune Sticks’ that upgrade towers with additional beneficial effects, or ‘Courage Sticks’ that increase enemies’ strength, but grant you additional rewards. It looks like these serve the same purpose as the ‘Mystic Arts’ we used in the Liyue version. It also seems we will still earn Veneficus Points, and presumably Sigils, too. We’ll explain all the changes once we know more details, but until then, you’ll find our comprehensive guide to the Liyue version below.

How to play Genshin Impact Theater Mechanicus

To play Theater Mechanicus, you need to speak to Ruijin – she’ll take one Xiao Lantern per attempt. These are crafted at a Crafting Bench from a Lantern Fiber, Wick Material, and Plaustrite Shard. If you’re looking for Xiao Lantern materials, Plaustride Shards drop from breaking ores, Wick Material drops from hilichurls, and Lantern Fiber comes from harvesting plants.

Theater Mechanicus is essentially a tower defense game, and can be played solo or in co-op mode with another player. Each stage consists of several waves of enemies; enemies enter through the purple portal and move through the stage toward the blue portal, which they escape through if they make it all the way there without being defeated.

To stop monsters escaping, you construct towers, known as Mechanici, during the timed construction phase before each wave. You can see the paths that the incoming wave of enemies will take, marked by a glowing trail, plan your tower placement accordingly. Building Mechanici will cost Veneficus points, which are earned by defeating enemies and using Mystic Arts.

You can refund your Mechanici for part of their Venificus point cost, or reconstruct them into a different type, for a fee. Completing challenges will grant you Veneficus Sigils, which you use to unlock and upgrade your Mechanici in the armory after each stage, which enables you to take on more difficult challenges.

Theater Mechanicus Mechanici

There are several kinds of towers that you can build to fend off the incoming swarm of beasties. Each tower has different attack effects based on its current level, gaining new abilities at levels three and five. Higher level towers are also more expensive to build.

  • Tidal Flats – Hydro AoE damage; applies Wet
  • Spark – Fireballs with Pyro damage
  • Thin Ice – Cryo bullets
  • Thunderstrike – Electro damage
  • Recovery Mechanicus – Generates bonus Veneficus Points for each opponent defeated in an AoE around it.
  • Gust – Knocks back enemies with Anemo. Unlocks on February 11
  • Longbow – Shoots arrows that deal Physical damage. Unlocks after reaching Guests From Afar
  • Desire – Buffs towers. Unlocks after reaching Guests From Afar
  • Ambush Mine – Deals massive Pyro AoE damage. Unlocks on February 12
  • Portal of Wonders – Allows you to teleport between portals. Unlocks after reaching Glow of a Thousand Lanterns

Theater Mechanicus Mystic Arts

After each wave, you can choose a Mystic Art to apply to the stage. These Mystic Arts apply various effects, such as granting extra Veneficus Points, enhancing Mechanici, buffing certain Genshin Impact elements, or even increasing the wave’s difficulty level, allowing you to earn more Veneficus Sigils. Some of them – marked with Fickle – will give you negative effects; you won’t see the precise nature of this debuff after you select it, so be very careful when picking Fickle – you might get in a pickle.

Theater Mechanicus tips

  • Check the stage features to see the oncoming monster types as well as the available challenges each round.
  • Construct Mechanici during the round as you acquire points – you don’t have to wait for the building stage.
  • Enemies can spawn from multiple portals; make sure you build towers to cover the intersection of lanes and not just directly in front of the portal.
  • Stages have special features you can activate for a fee – and on a cooldown – to destroy monsters.
  • Try not to stack elemental effects; avoid placing towers of the same elemental type equidistant from the wave, as this will result in the towers applying their effects simultaneously.

The best Theater Mechanicus party composition

You can’t deal damage to monsters yourself directly, but you can use Elemental Skills to apply elemental effects to them. You can also use charged attacks to knock them over and push them back toward your towers.

Cryo and Hydro heroes are particularly useful in this mode – with the right team composition, you can constantly freeze enemies, though as of the most recent patch, you can no longer deal shatter damage directly to foes.

  • Geo Traveller’s elemental skill and Genshin Impact Zhongli’s pillars can block the path, preventing enemies from getting past.
  • Zhongli’s elemental bursts are also incredibly strong.
  • Jean’s E can throw enemies over the edge into the central pit and kill them instantly.
  • Sucrose’s AoE gathering skill is also useful.
  • Ningguang can stagger enemies, forcing them to stand still.
  • Ganyu or Kaeya combined with Mona or Barbara can keep enemies permanently frozen.

That’s everything you need to know about the Genshin Impact Theater Mechanicus minigame. If you’re curious about what awaits you in the Inazuma region, we’ve got the latest on all the Genshin Impact new characters and the Genshin Impact Electro Traveler build.
