To put it Simple, you have to safe up 4000 Hero Spirits.
And you should't buy any perk further than Father's lesson.
When you got the 4000 Spirits, rebirth and then buy all of the quick level Perks (they come after the father's lesson perks)
Then you got every quest at least Level 5, also the Search for new Worlds quest.
It took 6 days to complete the quest for me, but then i got the Armor games Quest.
