I Tried to Find the Rarest Dungeon

I tried to find the rarest dungeon in RotMG! It's called the Consolation of Draconis, and Craig seemingly has a small chance to open it when encountering him in Sprite World. In this video, I hunt him down several times. Do I find the dungeon? No, I don't, but I find some interesting Craig dialogue along the way! Make sure to comment if you find this, I'd like to know how rare it actually is.
