Right breast damage:

Crushing/bludgeoning:
1: lucky idiot- it just grazed you. Minor pain, no other effect.
2-3: bruises- pain, no other effect.
4: winded- moderate pain, temporary minor inability to breathe (3 turns).
5-6: heavy bruises- moderate pain, muscular stiffness in ~30 minutes.
7: bruises- pain, roll 1-10: if less than 8, no effect. If equal or higher, bruised lung. Moderate pain, neglible bleeding, minor difficulty breathing for a few days.
8-9: bashed rib- moderate pain, bruising, roll 1-10: if less than 7, no effect. If equal or greater, take a roll on the Penetrating table.
10: broken clavicle. Severe pain, bruising, mostly useless arm on that side. I say mostly useless because moving it hurts so much nobody'd do it if they had a choice.
11: bruises- pain, roll 1-10: if less than 9, no effect. If equal or higher, bruised liver. Minor but sustained internal bleeding, moderate but sustained pain.

Slashing:
1: lucky idiot- it just grazed you. Minor pain, negligible bleeding, no other effect.
2-3: sliced skin- pain, minor bleeding.
4-5: gashed skin- moderate pain, moderate bleeding.
6: as 4. Roll 1-10: if less than 7, no change. If equal or 8, the blade slips between some ribs and cuts a lung. Minor bleeding, minor difficulty breathing (and associated panic), coughing up blood. If 9+, it gashes it. Moderate bleeding, moderate difficulty breathing. Coughing up blood.
7: crunched rib- moderate pain, minor bleeding, roll 1-10: if less than 7, no effect. If equal or  greater, take a roll on the Penetrating table.
8: broken clavicle- severe pain, moderate bleeding, mostly useless arm on that side. I say mostly useless because moving it hurts so much nobody'd do it if they had a choice.
9: severed muscle- reduced range of motion in the arm.
10: as 4. Roll 1-10: if less than 8, no change. If equal or higher, the blade slips between some ribs and gashes the liver. Heavy bleeding, severe pain, likely death unless you've got some haemostatic agents.

Penetrating:
1: lucky idiot- it just grazed you. Minor pain, negligible bleeding, no other effect.
2: glancing hit- the blow deflected off a bone and/or just took off a bit of skin. Moderate pain, minor bleeding.
3: minor hit- the blow didn't hit anything important. Moderate pain, moderate bleeding. If projectile, it lodged in place.
4-5: punctured lung. Roll 1-10: if equal to or less than 5, minor bleeding and breathing difficulties. If higher, moderate bleeding and breathing difficulties.
6: broken clavicle- severe pain, moderate bleeding, mostly useless arm on that side. I say mostly useless because moving it hurts so much nobody'd do it if they had a choice.
7: damaged lung. Significant hypoxia, moderate bleeding. This is what they call a "sucking chest wound", and as you might expect from the name, it sucks. In multiple senses of the word.
8: roll 1-10. If less than 6, see 3. If more, your aorta is punctured. Severe pain, incredibly heavy bleeding.
9: punctured liver. Roll 1-10: if equal to or less than 5, heavy bleeding and severe pain. If more, as before but with very heavy bleeding.
10: heart. Severe pain, incredibly heavy bleeding.
