Me and a friend were discussing gnome barbarians, and the fact that Small creatures have disadvantage on an attack when using a weapon with the heavy property. I brought up that the Enlarge/Reduce spell would negate this disadvantage by making the gnome have a size of Medium temporarily.
Though, the Enlarge/Reduce spell also causes creatures to do 1d4 extra damage with weapons they use. If a gnome/kobold/halfling/goblin were to hold a greatsword, and have a wizard enlarge them, it appears that, not only would the disadvantage imposed by being a Small race be removed, but they would also do 1d4 damage more than any normally Medium character using the weapon. This makes no sense to me, though; am I reading everything correctly?
Does a Small race do extra damage when enlarged by the Enlarge/Reduce spell?
