Sanguine Fizzle
A crimson powder, consumed by snorting it. It is a highly controlled substance that is illegal to produce and consume throughout the archipelago. It is made from the juices of the Sanguine Milkcap mushroom.
When consumed, you must make a DC 14 Constitution saving throw. On a failure, you fall unconscious for 1 minute (another creature can use its action to shake you awake). On a success, you instantly gain the benefits of a short rest (although you cannot spend hit dice). Regardless, you gain one level of exhaustion at the end of your next long rest.
If you are suffering from Exhaustion from consuming Fizzle when you consuming more, you have advantage on the Constitution saving throw, and those Exhaustion levels are suppressed for 8 hours after consuming it.
