Brew of Endurance

After carefully brewing a pot of tea for an hour, the drink can grant amazing endurance for the next 24 hours to four individuals. During that time whoever has drank the tea is immune to exhaustion and poison as well as having advantage on all Intelligence and Constitution Saving Throws. They also gain 3 D8 temporary hit points during that time. 

Once the tea has been made it must be drunk within 10 minutes of the casting ritual being complete. Once the tea has been drunk, the pot in which it was brewed becomes cracked and corroded and is unable to be used in this way again. 

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher you can add one additional recipient of the spell.
