I really want to know what a turn is

[saber_alter]

This is not a joke. I have been playing mmorpgs for 18 years. This is the first mmo I have played where something is called a turn in a raid. Please answer lol I feel so stupid.

Turn is a term used for the rooms in the binding coil of bahamut.

each section or "Coil" is seperated into several parts, or "turns."

the first part was seperated into five turns, while the rest have four.
