At Lucky Charm 5+, you can get Gold, Precious, Common, Magic, or Rare items.
like I said originally, so at least admit I was bloody well right.
I've seen it happen literally DOZENS of times on chests and containers that ONLY ever generate common items, but when I get a lucky find notice, lo and behold there's now a rare at the end of the treasure.
NEVER HAPPENS unless I get a lucky find.
