Sanctuary, Clinic and Laboratory

Why is the Sanctuary so important?

The Sanctuary is the main level of your city. The maximum level of heroes, the level of other buildings, the opening of new buildings, new game mechanics and additional units depend on it.

Starting from early levels, increasing the Sanctuary increases the maximum level of heroes. Therefore, stopping the Sanctuary begins to slow down almost the entire account.

Clinic - hidden wall

The clinic looks like a separate mini-game. Because of this, a beginner can easily decide: “I’ll deal with her later.” This is one of the most unpleasant early mistakes.

To upgrade the Sanctuary you need stars of the Clinic:

By level 28 of the Sanctuary, all the progress of the Clinic will be required.

Why can't you leave it for later?

You can catch up with the construction building: collected resources → applied acceleration → finished. This won't work with the Clinic. A few lost days can later turn into a real stoppage of the entire city.

What to do

Come to the Clinic every day. Treat patients, improve available rooms and move the stars further. You don't need to optimize it perfectly from day one. The main thing is that progress never stops for long.

Laboratory - second wall

The laboratory opens after level 7 Sanctuary. Later it becomes an almost constant requirement of the Sanctuary.

For Shrines 11 Laboratory 7 is needed. Then the rule is simple: Sanctuary N → Laboratory N−1.

At level 12, this requirement no longer disappears.

Don't wait until you need a Lab

Bad scenario: The Sanctuary is over → the game requires a Laboratory → you start building the Laboratory → you wait.

Correct scenario: While the current Sanctuary is being built, the Laboratory for the next one is already being prepared. Then one construction site naturally transitions into another without a long pause.

How to plan development

Before launching the next Sanctuary, check three things.

1. Are there enough stars in the Clinic?

If it is already clear that the Clinic is lagging behind, take care of it right away. Not when construction is finished. Now.

2. Is the Laboratory ready?

After Sanctuary 11, the landmark is simple: The Laboratory should be about one level below the next Sanctuary.

3. What other building will be needed?

Additional buildings vary from level to level. It is better to prepare them while the main queue is occupied by the current Sanctuary.

Convenient scheme

Let's say you're building Sanctuary 19 → 20. Look at the requirements of Sanctuary 21 now.

• develop the Clinic;
• prepare Laboratory 20;
• prepare the second required building;
• collect resources.

Once Sanctuary 20 is over, the next step is almost ready.

What is more important: Clinic or Laboratory?

If both are behind - don't let the Clinic stop first. The laboratory can be expedited. The clinic cannot be closed with a construction accelerator.

The laboratory is a construction planning issue. Clinic - question constant progress over time.

Don't push the Laboratory too far forward

There is no need to send the Laboratory several levels higher than necessary. Resources and time will be available for other mandatory requirements.

Optimal guideline: keeping it where the next Sanctuary needs it.

Common mistakes

• Ignore the Clinic in the first days.
• Remember the stars only after the red requirement of the Sanctuary appears.
• Don't look at the next level requirements in advance.
• Allowing the Laboratory to fall behind several levels.
• Build the Laboratory only after it has blocked the Sanctuary.
• Trying to pump the Laboratory too far forward.
• Consider resources as the main constraint on city development.
