Tamh Gon's Fiery Festival Feast

You sanctify a meal in an extravagant show of thrown
spices and twirling dance. Those who partake in the meal
are granted the curry blessings of the great festival spirit
Tamh Gon. The feast takes 1 hour to consume and the beneficial
effects don’t set in until this hour is over. Up to twelve
creatures can participate in this feast.
A creature that partakes of the feast gains several
benefits. The creature reduces its exhaustion level by one,
its speed increases by 10 feet, and it gains a +2 bonus to
Dexterity saving throws. It can also activate the effects of
the Ember Belly spell one time while the benefits of the
feast last. The feast’s benefits last for 24 hours.
