Thor: God of Thunder

To get this achievement, you have to use your wind power (Y) to extinguish the flame on the warlord enemies on Muspelheim. The warlord enemies are the ones which stand on two feet and carry swords.

I forgot about this achievement until the place where you are destroying the anchors to the drill, and still managed to get it by the end. It is a difficult achievement to track and actually not easy to tell if you have extinguished it or not, but just knock them over with the wind power and it should count towards your total.

Easy achievement to do, if you remember to do it.

I Wanted To Give My Insight On How I Unlocked This Achievement, Incase Other People Are Having A Hard Time Like I Did, Many Websites Just Told Me To Use A Wind Attack On The Warlords, But No Matter How Many Warlords I Hit With The Wind Attack The Achievement Would Not Unlock, How I Finally Got This Achievement To Unlock Was By Using The Cyclone Attack Against The Warlords, And Just To Be On The Safe Side I Used The Cyclone Attack To Kill Them As Well, You May Have To Activate Cyclone More Then Once To Kill A Warlord, That's How I Did It, And I Hope It Works For Everyone That Reads This Too!

On the Muspelheim level you will meet enemy's called flame carriers, tall demons with swords covered in flame. Use your wind powers on 10 of these guys throughout the level to get this.
There are loads more then 10 of them and even some in the next level if you don't have it by then.
