Blueberry Cupcake's Curse

You have eaten the blueberry cupcakes that were abruptly served to you by the skeleton triplets of the Aching Boar. You gain the following benefits:

• You suddenly and almost inexplicably feel a hunger for something unusual, sand.
• As long as you continue to consume sand (at least once an hour) your affinity for the earth grants you resistance to poison damage.
• You have advantage on saves against being poisoned.
