For reference: Amazon releasing 6.2 patch notes early
There’s a “new quest type”, which I assume is just more quests in the kingdom, not really an event. And “Adventurer’s Path” is probably just like a static, ever present campaign, with “Hero Pass” unlocking the paid track of rewards for it.
I don’t expect anything useful out of this one for most players, other than a chance for Explore to give some extra rewards. A bug fix or two would be nice too.
