Speaking of exhaustion, if you have 5 levels of exhaustion, can you benefit from bonuses to speed from spells or items? Longstrider's +10 or Boots of Striding and Springing setting your speed to 30 if it's less than 30?

Having 5 levels of exhaustion reduces your speed to 0, but it doesn't prevent bonuses to speed from applying to you. #DnD https://t.co/jnPQOD4eF3
