Understanding rarity scale
Hello - as I understand, rarity can be entered as 0-4 where 4 is very rare and 0 is common. 
Two questions that will help me decide what I want to be very rare vs items I'd like to show up more often.
  1. What number is equivalent to "vanilla"?
  2. Is "2" normal or no change to rarity?

"Very rare" would be equivalent to vanilla , "2"  would be possible to find but not that common.
