Finally Got that evil thing :)

How do you reach that?! And, is it worth the trouble?

Yes compared to other quoins I got it around 8 times already by getting under some security measures of hell. No, I will not mention how to do this unless you are a great friend of mine, and so far, I got 28, 42, 45, 48 favor each time (these are all that I remember( and you multiply that by the 11 giants too to get massive favor amount). And this spot is reliable, quoins summon regularly, unlike the ancestral lands.

But if you really want to next time both you are on and I do this again I can summon you to hell (yes I CAN in fact do that if i wished).
