You can use the Detail Tool to modify health of dolls+armour, as well as damage for some items with functionality. Melee weapon damage is physics-driven for cutting/blunt and can't be modified apart from making the weapons heavier/lighter. Firearm damage for plain bullet weapons depends on the velocity+size of the projectile, which you can modify using some of the attachments.
