Treasure Coffer
From FFXIclopedia, the free Final Fantasy XI encyclopedia
These are coffers containing treasures that are found in some dungeons throughout Vana'diel. Coffers are typically in higher level areas and have better contents than Treasure Chests. In order to open a coffer, you either need the appropriate key, or need to be a Thief with a lock-picking tool. The keys to open the coffers are dropped from specific mobs, which are usually located in the same zone as the coffer.
When you open a coffer you will either randomly get one of the possible items, some gil, or a quest item if you have a pertaining quest active.
Coffers cannot be opened while invisible or weakened, and opening a chest will result in losing effects of Sneak and Deodorize, possibly in aggro range from surrounding monsters, so special caution should be used when opening one.
Treasure coffers repop approximately 5 minutes after being opened; however, if another player has recently opened one and did not receive either a map or item for a quest (such as Artifact Armor), you will be unable to open another coffer for a random amount of time (sometimes it takes many attempts before you actually open the coffer, sometimes only 1 other attempt, shortest time is 15 minutes, longest time has been 1 hour) if you're not recieving key items or AF. If you try to open another coffer before this cool-down period expires, you will get following message: "The chest was but an illusion..."; the coffer will despawn, but you keep the key. When you receive this message, treasure coffer will repop within 5 minutes.
