rolled 6 = 6
Well, from what I understand, we are aiming to be more powerful in the short term until our size stabilizes, a succubus in the medium term until we've acquired a lot of power, and some sort of demon queen in the long term as a goal we'll probably never reach but towards which we will always strive. So, we're looking for more deals to make until we become a succubus. So, I dunno, interesting soul-getting encounters, ideally with bigger risks having more than one soul as payoff, with smaller risks having just the one?
As for drawing, I would suggest a drawing of our character in her natural demon form. In fact, I would suggest a new drawing at the start of each thread, to show how the character has progressed and what loot they've gotten. The next quest would probably show our preteen-looking blue demoness wrapped in a cheap, brown blanket as a sort of makeshift dress/toga, horns, tail, and hand-mouths clearly visible..
Know what I mean?
