Potato Farmer

You grew up tilling the fields for the potato harvests, and by son-son-potato you will die tilling potato fields. Other halflings might be wisked away by wizards in strange robes, or be kidnapped by roving bands of orcs (only to go on their own adventure full of danger and old trees).

However, your devotion to farming potatoes has given you an instinct to the call to adventure tropes. You have learned how to hide behind barrels from plot hooks, and how to stuff your ears with cotton so you don't hear dwarves knocking on your door.

Nobody home but us potatos!

Starting at 1st level, you can use the bonus action granted by your Cunning Action to make a Dexterity (Stealth) save in response to the game master introducing a plot hook or relevant NPC. You evade the call to action by hiding behind the nearest object. On a successful save, nobody notices and the game master has to switch back to Farming Simulator 2000 TTRPG.

They're taking them to Isengurd

Starting at level three, you have developed a sense of danger similar to your sense of oncoming storms. You know the direction of the arc's big bad; best to avoid anyone coming from there.

Supreme Sneak

Starting at 9th level, you have advantage on a Dexterity (Stealth) check if you move no more than half your speed on the same turn.

Boiled and Mashed

You have learned how to boil them, mash them, stick them in stews. All forms of cooking potatoes are open to you.

Addictive MSG

By making your potato chips addictive, you've managed to pull the entire rest of the party into your potato dreams. All of the party is now roped into helping you on your potato farm, and are forced to change class to potato farmer. The game master should also choose between Farming Simulator 3000 TTRPG or Potato RPG as the new rule system.
