To get right to the point, we have a way to use food outside of feeding dragons, but we don’t have a way to burn up wood aside from giving it away.
My idea is since the incubator is in theory cooking a dragon egg with fire, is to implement a tiered way to fuel the incubator with wood to reduce its hatch time.
For example, a sapphire dragon could start at say 1m wood to reduce it by a day. Once you reach the first day, the next day reduction would require double the amount of wood as the previous requirement, and so on and so forth. You could also maybe limit the boost to a certain number of times per 24 hour period.
Other tiered dragons could be scaled accordingly.
What’s everyone think?
