Hi,
There are a few things I still haven't been able to figure out about Lucky Charm and Bully... Any help would be appreciated

Questions about Lucky Charm:
1. Is Lucky Charm's item drop chance a party shared stat (ergo, the more ANYONE in your party has, the better your chances), or only the person opening containers and such needs it?
2. When I add points to Lucky Charm, I don't see any changes to Offensive Rating, unlike the description states. Is this intentional? Am I missing something?
Question about Bully:
1. Does Bully affect spell damage and / or Ranged attacks? Or only melee?
Thanks in advance for any assistance.
