1. No they will be there forever unles you discontinue the effect or log off but then you can just use it again (minus Cultist)

2.They are obtained by killing there respective hard mode boss for the first time but then cannot be obtained again therefore you can only get ONE of each variant. They are ment to be a useful advancment in the game as you progress to make it easier.

3.That's a good idea.
