I’m 24, I practice fencing. My height is 198 cm, I usually fence against shorter opponents. They often manage to drive their smallsword into my belly. That’s why I’m curious: what would it be like to get wounded into the belly by a real smallsword? How lethal would it be? How painful? How would I react?
1d6 in piercing damage but hit to the guts is probably a crit so 2d6. If you are lucky you will just be very injured. If you are unlucky you will go down and start doing death saving throws.
That’s why you always have a cleric in your party.
Or a necromancer
