I had six rolls, and I kept waking up periodically throughout the night and doing one and two-off rolls. Here's what I got.
Shadran
Durga (kind of neat)
Perseus (even though his stats are obviously Balanced maybe he'll get an Attacker ultimate some day?
Cursed Dragon (ha ha he looks funny at least)
Cinderella
I was considering saving my last five stones for an emergency. But then I thought about it, and figured that I might as well go for it since even if the Sun Quan drop rate is infinitesimally low I have to say I tried because it might be months and months before I get another shot even this good at him. You probably don't remember this, but on my first real godfest that I dropped a bunch of stones on I did the same thing and it got me a Gabriel on the very last roll. Well, I bet you can guess what happened this time. Spoiler alert:

Guys I think I won PAD.
For all of the various inconveniences and bits of bad luck this game has thrown at me, now I know for sure that it secretly loves me. I've never truly been fucked over on skillup projects, and this kind of thing keeps happening. The only tiny bit of negativity is that it'll take forever for a dungeon that skillups him to roll back around. Have the Dragon Knight dungeons shown up as or given any signs of being coin dungeons, by any chance?
