The video is short, but my God, she understands what goes into designing a challenging dungeon.
Trick rooms, false treasure, lave, traps, bad guys, wizards, and limited access. All in just over a minute.
She has never played D&D or any of its variants yet. She has played some of the Dungeon boardgame and two sessions of No Thank You Evil!
I suspect she will be a natural :)
So, with the children in your family circles, are you leading them into the corrupted future of "fantasy roleplaying?" ;)
