5 and 1/2 days is my MC prediction

I might be wrong on this, going from memory, but doesn’t honored allow you to purchase a single use quintessence once a week per character where as revered gives you the reusable one? Eternal Quintessence or something?

You actually made me have to hunt for this info and I think you are right.

Quest of Heros Reward must be completed to get Aqual Quintessence.
Revered for Eternal Quintessence introduced in patch 1.11

EDIT:

Technically, wouldn’t they just need to get multiple players of the raid group to honored so that multiple can buy the single use weekly ones? I still think 5 1/2 is impossible,

Actually with the Aqua Quin… I am reading old info that 1 person could buy, use (unique), then return buy and use. Not sure if this was ever changed.
