Researches unlock global tiers, improve doctrines and open new strategic capabilities.
/
Global progression
Researches are long-term choices. They can unlock actions, increase capacities or improve systems that are already available.
Unlike buildings, a research often serves the whole empire in the world where it was completed. It becomes especially important once the player controls several bastions, outposts or routes there, but its level never carries into another world.
Ash Cartography has three levels and requires a level 2 Ravenry. Level 1 unlocks Explorer training and sector surveying; level 2 shortens those journeys by 10%; level 3 raises the reduction to 20% and permits two simultaneous explorations.
Choosing the right moment
Research started too early can lock resources that were needed for defense. Research started too late can block colonization, outposts or cooperation.
Every research level and queue belongs strictly to the world where it was started.
Check requirements before planning an upgrade chain.
Compare strategic gain with immediate defensive needs.
Anticipate researches that increase limited capacities.
