Glimpses of Hyboria
Minimum Damage (two cases)
Minimum Damage case 1: If penalties reduce the damage result to fewer than one, a hit still deals one point of damage.
Minimum Damage case 2: (Optional rule) If DR from armour reduces the damage of a successful attack to less than one, a successful hit still deals one point of nonlethal damage.
Case 2 Note: Primitive weapons: break if they strike ineffectively against metal armoured characters (that s, if the armour’s DR reduces the primitive weapon’s damage to zero before the minimum damage rule is applied.)
Case 2 Note: Sneak attacks only deal extra damage if the damage inflicted is at least one point after DR.
