Theater Mechanicus Strategy Points

Make Use Of Element Reactions

In Theater Mechanicus, characters will not be able to give damage to the enemies, but they can still use their Elemental Skills to infuse monsters with elements.

Recommended Characters

Great For Elemental Procs

Ganyu	Childe	Fischl	Klee
Mona	Yanfei	Barbara	Lisa

Bow and Catalyst users are particularly strong in Theater Mechanicus with how fast they can apply elements to enemies. Using characters that can hit multiple enemies at a time with their Elemental attacks are good!

Good For Crowd Control

Kazuha	Jean	Sucrose	Geo Traveler
Anemo Traveler	-	-	-

The following characters can stop enemy movement or interrupt their path. Take note that this will only work on smaller enemies and will not affect the larger ones.

Use Geo Traveler To Block Paths

If you are being overwhelmed, consider using the Geo Traveler to create blockage to the path of the enemies! Besides blocking the path, it also deals Geo damage!

Theater Mechanicus 2.6 - Tips To Win

Check Enemy List Before Placing Mechanicus

It's recommended to check the enemies that will show up in the wave first before placing down your Mechanicus. This will help you plan out which Mechanicus to place down to counter the incoming enemies.

Elemental Mechanicus & Uses

Mechanics	Good Against
Veneficus Mechanicus: Inferno	- (With Hydro) Vaporize deals good damage - (With Cryo) Melt does good damage - (With Electro) Overcharged does big damage and knocks back enemies
Veneficus Mechanicus: Furious Discharge	- (With Hydro) Electro-Charged can hit multiple enemies & stuns enemies - (With Pyro) Overcharged does big damage and knocks back enemies
Veneficus Mechanicus: Glacial Bloom	- (With Pyro) Melt does good damage - (With Hydro) Freeze enemies and prevent their movement
Veneficus Mechanicus: Rippling Reflections	- (With Cryo) Freeze enemies and prevent their movement - (With Electro) Electro-Charged can hit multiple enemies & stuns enemies - (With Pyro) Vaporize deals good damage
Veneficus Mechanicus: Dust Devil	- Swirls elements - Pushes back enemies - Can also pull in enemies

Anemo Mechanicus Is Only Good Against Small Enemies

Against small enemies, the Dust Devil Mechanicus is particularly strong since it can easily push them back. However, once you're fighting against bigger enemies, it will not be able to do that. It's better to replace it with another Mechanicus instead.

There Are Also Non-Elemental Mechanicus

Players can also place down non-elemental Mechanicus in the stages. Offensive non-elemental Mechanicus will inflict Physical Damage to enemies, which is great since it has no weaknesses and will affect all types of enemies!

Non-Elemental Mechanicus & Uses

Mechanicus	Effect
Veneficus Mechanicus: Crack Shot	Fires an arrow shot, dealing 75% ATK as Physical Damage on hit
Tandem Mine	Explodes when an enemy passes by it. Will deal 500% ATK as Pyro Damage to nearby opponents
Recovery Mechanicus: Charity	Decreases enemy movement speed by 20% and gives 20 extra Veneficus Points when they're defeated
Arcane Mechanicus: Binding	Imprisons an enemy for 3 seconds
Arcane Mechanicus: Banishment	Knocks enemy back every 6 seconds
Mysticus Mechanicus: Arcanum	Increasing ATK of neaby Mechanicus by 50%

Charity Mechanicus Do Not Stack

Note that Charity Mechanicus effects and the amount of bonus points they give do not stack. We recommend adding one on the slot closest to the enemy spawn or at an intersecetion where 2 paths meet.

Make Use Of Wondrous Sticks

Don't forget to get buffs through the Wondrous Sticks. It's recommended to choose wondrous sticks depending on the Mechanicus you plan on placing down in the arena!

Do Not Use Mechanicus With No Wondrous Sticks

Every stage, there will be Mechanicus types that will not receive buffs from the Wondrous Sticks. Plan your defense around this and only use ones that can have buffs during a stage.

Stay At Critical Positions

Dedicate a slot where you will just place Mines when needed. This is recommended at choke points at intersections. it's also good to have it at the frontline, right before your first line of defense.

Freezing Is Effective

Freezing your enemies in locations where Mechanicus are placed will be a highly effective way of defeating enemies and maximizing the damage from Mechanicus. You can save Mechanicus space by either using a Cryo or Hydro character.

Send Enemies To Holes

Another way of defeating enemies is to blast them into holes, thereby defeating them. This is very effective against small enemies. Anemo Travler or Jean can do this.
