Grumpy Dungeon Masters' Vault of the Grumpy Sphinx

Publisher's blurb:

“A crumpled note in your hand reads ‘BRING YOUR PARTY. THE TOURNAMENT BEGINS.’ You gather your friends, steel your weapons, and travel to the Grumpy Tabby Tavern. Inside a grumpy bartender greets you and asks if you are ready. With a flash of bright light, you are teleported away. As your vision adjusts, you find yourself in The Vault of the Grumpy Sphinx. The second Grumpy Dungeon Master challenge dungeon awaits you.”
