The better_artifacts.zip file you have requested: Clear Sky / Mods / Singleplayer / Better Artifacts - 4.65kb is not available. Perhaps try browsing all files for the game S.T.A.L.K.E.R.: Clear Sky and upload any files you want to share or are missing. This is the only information we could locate:
Artifacts that gave +1 or +3 resistance to something seemed a little pointless. Why would I irradiate my character for practically no benefit and miss out on a few thousand rubles? I therefore increased the protective properties of artifacts granting burn, chemical burn, electricity, and telepathy resists to make them more useful. All other properties were left the same.I made this using 1.5.03 files but have not noticed any problems in my current 1.5.04 game.
