Treasure items, Rolling up:
Always start by rolling on the Common, UnCommon, Rare, or Legendary chart, as instructed when you roll up any treasure item (it will tell you which rarity chart to roll on.
When treasure is found, there will often times be sub-charts indicating that more than one of the same treasure check has been found. If this happens, those treasure items found, whether they be one or more, will be counted as ONE treasure check. Four potions can be found with one check, and this counts as one check (not 4).
