Lucky Artifact

I was thinking of an artifact that can be used by all classes and has levels with timers. Its called LUCKY artifact and it increases X for a period of Y *
%. For example: an AM might get a higher chance at higher dmg weapon to be made. Or health/dd/shield drops spawn during the timer for all classes. So anything involving chance by any class would have an increase in that chance during the timed artifact use of Lucky.
Even the avoidance of Titan rocks etc. Just an idea!
