The artifacts I used, on my last trip through the game were :
Moonlight -- Adds 109% endurance but electricity hurts 10% more.
Urchin -- Defends 30 radiation but increases bleeding.
Mica -- large effect against bleeding (400%)
Meat Chunk -- Adds 400% life but reduces impact, bullet, and rupture.
and some +3% bullet cap .. not sure about some of those percents, they may just be a non percent addition.
I want to find:
Nightstar -- Adds 5 radiation, decreases bullet damage by 30%.
Soul -- Adds 600% life but reduces impact, bullet, and rupture.
Then there are the really rare ones:
Battery-A -- Adds 30% resistance against electric damage
Battery-B -- Adds 30% resistance against burn damage (see below)
Kobolok -- Adds 5% resistance against rupture damage
Mama's Beads -- Adds 5% resistance against bullet damage
Pellicle -- Adds 30% resistance against chemical damage
Spring -- Adds 30% resistance against impact damage
