I invested just 200 Amity to Bipache and it was enough. But after this, i think its just important to have just "a bit" at him".
And at Theophil batian have I only 10amity, but I did never make any minigame with him.
The 500 Amity @Theophil is only needed to speak with the Leader. Herman Feresio.
And 500 Amity with the guard at the entry.
