Stability
Part of the Population guide
Stability is how happy a system's population is. It starts at 35, and population lowers it. Each whole point of population changes stability by -1, and a fraction of a point does not count.
What it does:
- It speeds up population growth. Below 0 stability, population slowly shrinks instead. See population.
- At 0 or below, it gives the system a Population status that reduces its outputs.
- Higher stability makes a Siderian's Destabilize or Control more likely to fail.
Temporary penalties
A Siderian's Destabilize lowers a system's stability. Even a failure costs 5 stability, but a critical failure costs nothing. A success costs 15, and a critical success costs 20.
The penalty fades by 0.01 stability per tick0.2 stability per hour and disappears when it reaches 0. Several penalties add up and fade separately. Each one shows as its own Destabilization line in the stability tooltip, with what is left of it.
