Temperature – The Environment

The first major question is “What does and doesn’t affect egg hatching”? This is important to know as doing the wrong things won’t help. It’s safe to assume that egg hatching temperature is the same as player temperature – minus a few things.

• Normal, average climates have a resting temperature of -1 segment on the dial.
• Tropical climates (such as the forested area to the north of the marshlands) have a resting temperature of 0.
• Cold and snowy areas have a resting temperature of -3.
• Deserts have a resting temperature of +2.
• The volcano has a resting temperature of +3.

This is specifically during the day. At night biomes decrease in temperature, resulting in the following spread:

• Average climates now rest at -2 (down 1).
• Tropical climates remain at 0 (unchanged).
• Cold and snowy climates rest at -3 (down 1).
• Deserts, being the largest exception to this rule, now rest at -3 (down 5).
• The volcano now rests at +1 (down 2).

Understanding Placeable Heat and Cold Sources

What Does What?

Campfires passively raise temperature nearby by 1.

Heaters raise temperature nearby by 1 as long as there is a Pal with Kindling proficiency working at the heater. The level of proficiency does not matter (I.E. a level 1 kindling heats as effectively as a level 3 kindling).

Coolers passively lower the temperature nearby by 1 as long as there is a Pal with Cooling proficiency working at the cooler. Just like heaters, the level of proficiency does not matter.

Electric heaters and electric coolers require both a Pal and electricity to run, but change the temperature by 2 segments instead of 1.

Source Interactions

Multiples of a temperature source do not stack. Placing 100 campfires will give you the same temperature as placing 1. Save your wood.

Different temperature sources also do not stack. Placing a campfire and electric heater will still only give a net +2 temperature.

Hot and cold sources also do not stack. If a hot and cold source are both active and affecting the same area, the cold source will be overridden and the temperature will only be modified by the hot source.

What Doesn’t Affect Temperature

• Enclosing the incubator in a structure does not affect the temperature.
• Deploying a fire-type Pal, while it does heat the player by one segment, does not affect the environment temperature and thus does not affect eggs.
• As stated above, multiples of a temperature source do not stack.
• Cooking pots, while they share a similar appearance and some similar functions as a campfire, do not emit heat.

Egg Temperature Requirements

There are 9 egg types; one for each element a Pal can be. Eggs can come in three sizes (normal, large, and huge) but as far as I’m aware this does not affect their temperature requirements.

Each egg has an “ideal” temperature. Being at this temperature doubles incubation speed. Eggs at this temperature will display the status text “seems very comfortable”. Being 1 segment off from this temperature reduces that bonus to only x1.5, signified by the status text saying “seems just a little hot/cold”. Being 2 segments off reduces the bonus to x1, and causes the status text to display as “seems a little hot/cold”. Being more than 2 segments off will change the status text one final time to “seems very hot/cold”, but does not further impact incubation speed until you reach 4 away from ideal, which causes the incubation speed to drop to -25%.

Common (A.K.A. “Normal type”), verdant (grass), and Electric eggs all have an ideal temperature of 0. This can be achieved using a campfire or normal heater in any average climate, or by building the incubator in a tropical area.

Damp (water), Dark, and Frozen (ice) eggs have an ideal temperature of -1, which is equivalent to an average climate at day.

Rocky (rock), Dragon, and Scorching (fire) eggs have an ideal temperature of +1, requiring an electric heater or warmer climate to hatch at maximum speed.

So What Does This Mean?

A brief important note: the desert areas seem to have unusual effects on egg temperature, causing the -1 temperature eggs to forget their ideal temperatures. -1 temp eggs become +2 temp eggs while in certain spots of the desert. As this makes absolutely no sense and is likely a bug, I will be giving advice as if the desert climates behaved “normally”, but keep in mind that until this bug is fixed deserts should be avoided.

You can achieve ideal temperatures with the following setups:

Normal, Grass, or Electric Eggs (0)

1. Just the tropical biome at any time.
2. Any temperate biome during the day with a heater. Using a heater over a campfire gives you more control over the temperature and allows you to hatch any kind of egg with only one incubator, if that’s how you want to do it. Once night falls, the egg will become too cold.
3. Any temperate biome during the day with a campfire. While functionally identical to the heater for this purpose, campfires cannot be turned off. As above, the egg will become too cold once night falls.
4. Any temperate biome at night using an electric heater. Note that the egg will become too hot once day breaks.
5. Deserts during the day using an electric cooler. Note that the egg will become far too cold once night falls.
6. The volcano at night with a cooler. Note that even with the cooler the egg will become much too hot once day breaks.

Water, Dark, and Ice Eggs (-1)

1. Just temperate biomes during the day. Once night falls the egg will become too cold.
2. Temperate biomes at night with a heater. Once day breaks the egg will become too hot.
3. Temperate biomes at night with a campfire. Once day breaks the egg will become too hot.
4. Snowy areas during the day with an electric heater. Once night falls the egg will become too cold.
5. Deserts at night with an electric heater. Once day breaks the egg will become much too hot.

Fire, Rock, and Dragon Eggs (+1)

1. The tropical biome with a heater.
2. The tropical biome with a campfire.
3. Any temperate biome during the day with an electric heater. Once night falls the egg will become too cold.
4. Deserts during the day with a cooler. Once night falls the egg will become much too cold.
5. The volcano at night. Once day breaks the egg will become too hot.
6. The volcano during the day with an electric cooler. Once night falls the egg will become much too cold.

Overall Hatchery Building Tips

The clear best place for a hatchery is the tropical area. The around-the-clock median temperature ensures you never need to use the expensive and bulky electric heaters and coolers.

The next best place to build is in temperate climates. Even with an electric heater you won’t be able to reach ideal temperatures on the +1 temp eggs around the clock, but if you sleep the nights away it can still work. It’s also the best place to hatch the -1 temp eggs with no heating or cooling at all.

Other biomes have temperatures that are too extreme and/or swing too wildly to effectively hatch anything at all.

It’s important to remember that these temperatures aren’t imperatives. You can hatch a very hot or very cold egg, it just takes twice as long.

A good setup would be to place one incubator down in a tropical area and place one heater and one cooler next to it. You can then assign and unassign pals to these based on the needs of the egg you’re hatching.

If you’d prefer to have one hatchery for each temperature, you can instead use a campfire for the heated incubator as the lack of Pal labor requirements makes it better if you don’t ever plan on turning it off.
