Our fc chest works like this: Leader and officers have full access. Only Leader has access to gil. Vip rank has access to first and second item chest slot levels. Everyone else has access to the first chest item slot level. I think almost everyone has access to crystals (minus the new people and low ranks) Anyone can donate crystals and gil. As you can imagine, third item slot is for the expensive items or rares and only the leadership has access. :P
