"Perform 2 prone attacks in a row." - That is or better should be the condition to get the Achievement, but as many of you know, this does not work. Some of you get this Achievement by accident and have no Idea why.

This Achievement isn't bugged, but the description is just incorrect as I know.

Since this Achievement is false described, I want to correct it, so you know what to do.

"Perform 5 prone attacks in one fight."

How did I get the idea of this discription?

1. I fought in one fight about 8 Lizards. I didn't kill all of them with a prone Attack, but many.
   Furthermore 5 is a good looking number. ;)

These are the 2 reasons why I get the idea of this description!

What is the prone attack?

The prone attack is performed, when an enemy lies on the ground and you character jumps to him and strikes 2 times: Left-Right;Right-Left
The last strike: Up-Down (which also kills the enemy) is actually the prone attack, but just if you really kill him. In case the enemy is not low-health he tries to dodge this Attack! -> No prone attack!

Equipment:

First of all, one sword is really important, cause this makes it way easier for you.
Blood Crescent:

You'll get this weapon after defeating the Lizardmen King.

The advantage is that if you start your prone attack, it skips the Left-Right;Right-Left and instantly starts the prone attack, which has a way higher chance to succeed on you first try!

Game-Mode:

Of course you also need 5 or more enemies to achieve this. I recommend you to make this in story mode, because you can choose which cards stay in your deck. That allows you to get the Blood Crescent easier and faster.

The only disadvantage is that you may not get a fight with 5 Enemies or more...

As you see this Achievement is not very hard to get. Just needs some luck...
However if you guys see that you need more than 5 prone Attacks, then I'm glad to see a comment. I'll update my Guide ASAP.

If this technique works on you. let me know, so I don't give you a false advice.
I hope this helps you. :)
