Found a santa chilling in Dark Dungeon. He only had one thing to say to me, but I didn't feel like using a translator to try language after language to figure it out.
Why is Santa in Dark Dungeon?
On another note, mini-bosses haven't / arn't / didn't spawn. Not sure which one of these you are intending, so.
On an additional note, Ifrit did spawn, and was killed, and dropped no loot. At all. Not sure if this is also intended.
