Mundane artifacts (luxury enabled by personal shielding tech) %Science Bonus operates at empire level... With at least 1 you get 8% total empire science (sum(SS)*1.08) ..With at least 4 you get 28% total empire science (sum(SS)*1.28) ...Obtaining at least 4 its whooping ~30% science output of your empire - huge



All the other % science modifiers operate at system level (check System level Science(SS) output mechanics here https://www.games2gether.com/endless-space/forum/33-strategy-guides/thread/14013-solar-system-level-fids-guide)



This is the only global Science multiplier I am aware of - and that makes it very strong ...





Edit correction - you get 2% per Mundane artifacts unit.. Up to 8% when you also get the monopoly bonus for the extra 20% ..

Also proto-orchid luxury fids bonus is also applied at empire level - but is applied before the bonus from Mundane Artifacts (they multiply)

All the artifact bonuses are 'huge'.



The Sophons get another empire-wide science bonus too, though, through their unique building.

Does this mean it compiles even the science gotten through trade?

Yup +8% or +28% extra for all science summed from all solar systems ... That includes science from trade routes ...

Will check that and update
