You summon 2 giant cotton mammoths that serve as loyal mounts and protectors. Each mammoth has the statistics of a rhinoceros but is made of soft cotton, giving them the following modifications: they have vulnerability to fire damage, immunity to fall damage, and their charge attack doesn't deal damage but instead knocks the target prone and pushes them 15 feet. The mammoths are incredibly comfortable to ride (removing 1 exhaustion level to a creature per casting of the spell) and can compress themselves to fit through spaces as narrow as 5 feet wide. They obey your commands and can carry up to 4 Medium creatures each.
