I starred a quest that Cyde-6 had as I spawned at the tower. Some steps involved in killing enemies with Golden gun and wining at the crucible and at the end I received a legendary cloak called Gunslinger's cloak. I then looked it up in the destiny data base and I also found out there's other cloaks which go with the other sub classes. I wanted to know if there's any other way to start the quest again in order to get all the other cloaks.

Switch to bladedancer before you enter the tower and you will be able to acquire the quest for bladedancer class item.
