The Research building is where players can exchange dragon eggs for research. When you research something, you exchange a certain amount of a specific color of dragon eggs for a permanent corresponding boost.
There are multiple tiers of research. The first tier is red, which is the first tier of breedable dragons. Then it continues in color order (purple, blue, orange, and so on).
What it Does
Researching can help give you various boosts, for example -5% Incubation Time, etc.
