Fable Anniversary

A good place to go for this is early in the game during guild training. When the Guildmaster trains you in melee. After you complete it and he tells you to move on to archery a hero in dark hooded robes comes to test your melee with the goal of getting an A+ rating to get the Iron Katana. You can try to defeat Whisper indefinitely by just talking to him again if you fail to defeat her without being hit.

As for doing so, use your block and roll and attack when you can do so without being hit. May take a few tries but it's not too difficult. There are of course more fights against Whisper further in the game but this way you can just retry until you succeed without reloading a save or anything.

Good luck!

This Achievement is best obtained during the melee training at the Heroes Guild.

You will have an opportunity to have a rematch against her once you complete the training. A guild member with a hood will come up and you can talk to him to fight her again. This can be done and unlimited amount of times. As for fighting her it is pretty straight forward simply block and dodge and roll using RB and then attack her.

This method is even faster than waiting for the rematch after might, skill, and will training.

During the very first fight with Whisper when you conduct block and roll training, use the third part of the training to get the achievement. Thunder will walk up and the Guildmaster will tell you to combine attack and defense. Whisper will get a health bar and the fight begins.

Hold block until she gets close. Try to roll slightly diagonal toward her so that you end up behind her. She will typically attack twice in a row. Wait for both strikes while blocking, then roll behind her after the second and start hitting her back straight on. If you are right behind her, you can sustain your attack until her health bar runs out. Don't use the flourish attack or you will knock her down and have to wait for her to get up. If you do knock her down, be sure to wait behind her so that you can start assaulting her again. Once she is out of health, the achievement will pop immediately if you were not damaged.

For this after you finish the hand to hand training talk to the trainer again and ask for rematch. Finish the combat inharmed. The easiest way is to hit him once, make a parry and when he attaks you hit him. Follow this till the combat is finish. You can try as many times as you want.In this video I talk in Spanish but I can be understood just watching it.
