Complete any campaign mission by having a party consisting only of women; Note: your party can consist of a woman and a dog (you can get a dog after one of your characters dies).

Evade 75 attacks. Do that by using Low-Profile mode - it can be used by every character wearing Medium Armor (this skill increases your chance to evade an attack by 40%). Remember, when you successfully dodge an attack, you will see Evade text, not Miss. Hiding behind covers doesn't count.
