Iron Gut

Constitution 13 or higher

You eat like a giant and drink like a fish. Years of punishing your stomach and liver have led to a powerful fortitude. You gain the following benefits:

• You have advantage on Saving Throws against being poisoned.
• Upon completing a long rest, you regain 1 additional spent Hit Dice.
• As an action, you can spend Hit Dice to heal yourself, as if you have taken a short rest. You can use this ability a number of times equal to your Constitution modifier (minimum of 1) per long rest.
