Prismatic Strand still locked

[Beatnbronco]

Prismatic Strand is still locked for my Hunter and Warlock after completing the campaign on legendary. I'm at the same step for every character and light level. I don't understand why this is. Anyone know??

Your main character earned it during the 'Destined Heroes' quest (including Lost in the Light/Found in the Dark).
Your alt characters don't get second copies of the quests, but do have access to the six adventures that made them up. They can be launched from banner staves at the Lost Tower and each unlocks a prismatic upgrade on completion. In particular, it is 'Home II' that unlocks the Dark Super.
