I've added templates for some time to Galaxy maps and often pre-place artifacts in them. One of the pesky annoyances when starting is trying to find the correct entry for each artifact. Following are the working entries for artifacts up to Diplomacy. All artifacts from all the original SoaSE work in ALL versions and expansions of Sins and artifacts added during Entrenchment will function in Entrenchment, Diplomacy and Rebellion.
Jump Drive Relic (Sins) -- Speed in wormhole lanes increased by 50% and jump charge up rate decreased by 25%.
Kinetic Intensifier (Sins) -- Weapon damage increased by 20% for all ships and structures.
Resilient Metaloids (Sins) -- Armor value increased by "1" and passive hull repair increased by 50%.
Power Core Relic (Sins) -- Antimatter capacity increased by 10% and passive antimatter regeneration increased by 15%.
Data Archive (Sins) -- Research cost reduced by 25% and research speed increased by 5%.
Relativistic Factories (Sins) -- Ship and structure build rates increased by 25%.
Jump Field Generator (Sins) -- Allows wormhole travel and phase jump antimatter costs reduced by 30%.
Phase Accelerator (Sins) -- Ship speed in phase lanes increased by 50%.
Manifest Dominion (Sins) -- Spread rate of culture increased 25% and resitance to hostile culture increased 10%.
Ion Field Generator (Entrenchment) -- Planet health bombing damage reduced by 40% and population loss reduced by 25%.
Matter Compressor (Entrenchment) -- Credits earned by trade ships increased 25%.
Planetary Organic AI (Entrenchment) -- Population tax credits increase by 25% and population growth by 40%.
Entrenchment artifacts can currently only be added by modding.
