Pharika’s Cure
Potion, uncommon
Price: 10-150 gp | no sentimentality
When you drink this potion, roll a d4. If you roll a 1, you suffer poison damage equal to your maximum hit points. The potion’s smoky, purplish-pink liquid hisses like a pit of snakes.
Paid
When you drink this potion, you gain the benefits of the greater restoration spell. You must still roll to see if you suffer poison damage.
Overpaid
You roll a d10 instead of a d4 to determine if you suffer poison damage.
