Demonling

[A goblin shaman.]

I feel like I might be missing the obvious...but where/how does one obtain the demonling class for the rogue?

Hi Goblin Shaman!
The key to obtaining the demonling class is obtaining the cursed box after beating the final boss of the cursed city. Once you get it I'm sure you'll have no problem unlocking it. ;)

Oh cool! Looks like I know what my next city run is going to be :). Thanks again!

Just unlocked the demonling! That was pretty cool, I know it's difficult to create a lot of quests for the subclasses like that, but I would be pumped if more classes were like that! Very fun.

Glad you liked it! :)
I have many ideas for quests like that and in the ideal card quest i would like all subclasses to be unlocked in that way. Unfortunately it´s a lot of work and my time is very limited! But I will probably be implementing a few more of these quests in the future. ;)

Yeah, I figured you have plenty to keep you busy. Just wanted to let you know I thought that quest was pretty cool!

Wait, how do you unlock it?
I beat the 666 demon after opening the box, then selected the demon heart as a reward instead of the box, used it, and nope, it didn't unlock anything.
What should I have done differently?

You're on the right track ;). Just keep using the heart!
