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%.
item "Artifact:HyperspaceSpeed"
Kinetic Intensifier (Sins) -- Weapon damage increased by 20% for all ships and structures.
item "Artifact:WeaponBoost"
