Losing & Death - Death often happens when learning how to win a BCNM. When a character dies in a BCNM they lose experience for the level they're at, which is usually the level cap of the BCNM. So a level 70 character who dies inside a level capped 40 BCNM, will only lose experience as a level 40 character. It is possible to run away from a BCNM by selecting the Burning Circle at the start of the fight arena, assuming that a mob isn't currently fighting your character. This is often done by the remaining characters if the fight goes poorly and many other characters have died. If everyone dies inside the BCNM, it will move everyone out after 3 minutes and end the encounter. Alternately, if Reraise is up, either from casting the spell or via an item, that can be used inside the BCNM after dying if there is still time left. The time limit is a constant enemy in BCNMs; if you take too long in the fight and the time runs out, you will be kicked out of the BCNM and lose.

Wrapping Up - Once an orb is used, whether you win or lose, it is changed into a cracked version in your inventory. This can be disposed of by trading it back to Shami, or by discarding it. You can repeat the BCNM as many times as you have orbs; once the party runs out of orbs, if you wish to continue you must return to Shami to obtain more by trading him more seals. Note that if you lose the BCNM or exit it from inside, you are put back into the starting section of the BCNM zone. When you win, however, you are placed on the opposite side and must walk back through the dungeon zone before getting to the FFXI Gil entrance again.

Non-Standard BCNMs - BCNMs have been added that don't use the standard orbs or Battle Circles; otherwise, they function like a regular BCNM. So far, the only non-standard BCNM in the game is Ouryu Cometh, a BCNM that is on an island in Riverne - Site #A01.
