Can anyone confirm if they're still dropping? I've been out trying to get one for a loooong time and haven't gotten anything.
Fastest way to get them is to go out and spawn!!
Based on the knowledge that spawns have lots of easy creatures to kill and that the chance of getting an artifact is based on the sheer number you kill. (IE: Kill 200 slimes/rats for an increasing % chance per creature killed or else kill 2 OL for an increasing % chance per creature killed in the same time.) The first option will give you the best chance for reward. Always. (at least as long as the same system is being used to spawn the artifacts.) Numbers over toughness.Based on what, exactly?
