Laboratory

The Laboratory unlocks after getting 10 Science. Certain research must be conducted in order to move on to the next world, but not all research is available in every world.

The multipliers listed are multiplied together, so that two 3x boosts to the same category will result in an overall 9x boost, and not a 6x boost.

Note that power boosts apply only to the exact item listed. E.g. A boost to shark power will apply to sharks, but not science sharks or nurse sharks.

## Eel Upgrades

These upgrades are available in every world that has eel.

So we keep seeing these things we thought were kelp on the seabed, but it turns out they're not kelp. What are they?
Unlocks
* Dig eel pit
* Teach eel technician
* Train eel sifter
* Crevice Creches
* Bioelectricity (also requires Engineering)
 Crevice Creches
We can probably figure out a way to make eel pits cosier for their inhabitants.

 Bioelectricity
There has to be a way to harness the powers of some of the eels. We all know they have powers. Painful ones.

## World-Specific Upgrades

These upgrades are available in only one world each: Abandoned, Frigid, Shrouded and Shrouded respectively.

So the machines might be destroying the ocean. We need to fix this.
 Thermal Conditioning
We're freezing to death! Machines make heat, right? We need to work on this!!
 Chimaera Mysticism
We know the chimaeras, but we don't [understand] them very well. We need to adjust our thinking to understand their riddles.
* Induct chimaera transmuter
* Prepare chimaera explorer
* Abyssal Enigmas
 Abyssal Enigmas
The chimaeras have returned from the deeper oceans with artifacts they can't explain. We need to work together to understand them.

## Trivia

Normal pens and paper don't work underwater, but pencils can still be used with specialized writing surfaces. Several types are available, ranging from simple plastic to screens embedded with magnetic particles. You can even buy traditional notebooks filled with waterproofed, tear-resistant paper. The most commonly used underwater "clipboards" are inexpensive standard dive slates: small plastic rectangles, often with a pencil attached and a place to hook it on to your person.
