From publisher blurb:
New monsters! New Spells! New Classes!
Featuring art from the insanely talented Luka Rejec, this weird fantasy/western adventure is set in the high desert. Join forces with the bandit king that is kidnapping babies to save the world, or bring him to the stern justice of the Sisters of Clemency. Choose carefully, for either would make for a powerful enemy. The Sisters can harness the power of volcanoes themselves, and the bandit king leads an army of 10,000 tuber dudes.
Designed to be a minimal preparation one-shot adventure, Invasion of Tuber Dudes brings the Weird onto your tabletop. It’s the Good, the Bad, and the Ugly meets Attack of the Killer Tomatoes mashed up into D&D!
