The Best Artifacts i think are the butterflt lamps. There are 2 in the game. The 1st one is in the basments with the bugs, and the 2nd one is on the side of the room where the bug nest is. To get maximum value, you need to colect 3 colored eyes, red, green, and blue. They can be found by killing bugs and each have a different drop rate, Green being the highest, and blue being the lowest. There also a way to get a full set without killing bugs too. When you pick up the 2nd butterfly lamp, there is a opening in the wall where you can see the bug nest. Shoot it about 30 times with a handgun and it will fall to the ground, leaving around 10 eyes on the ground. There will always be 1 of each color.
