This achievement is called "Kayranslayer" to obtain this achievement you must complete the quest called "The Kayran".
This is more or less your first "boss" fight in the game, if you went ahead and made a potion called "Ostmurk" use that before heading down to fight it. Once the cut-scene activates dodge its tentacles and and activate your "Yrden" sign and plant it in the path of one of the four outside tentacles (not the two middle ones...this will trap it next time it comes down...then hack away at it when its trapped...do this with two more of the tentalces...keep doing this til Geralt grabs ahold of another tentacle and button mash A.
The bridge it keeps hitting will fall on top of it...run up the sloped side while dodging past the tentacles and enjoy the cutscene and your achievement. Don't forget to loot the body!!!

Once the Kayran goes down, DO NOT RUSH THE RIGHT SIDE! I brilliantly ran in for the far right tentacle after the large pillar fell on the beast, thinking I still had to sever it. I ended up trapped between the Kayran's body and the rocks, with a tentacle around me so that I could go nowhere. I had to continuously suffer the electrocution from getting to close to the Kayran. I died, had to load my recent autosave and fight the beast all over again.

Story related, and cannot be missed. The Kayran is the first main boss in the game, and it really isn’t too difficult if you know what to do. You can use the trap you crafted for the ”Artful Dodger” achievement, but it isn’t necessary if you already have the achievement or don’t care about it. Here’s how to beat him without using the trap on Dark:
- Immediately cast Quen whenever you’re hit and right when the fights starts.
- Cast Yrden to put down a magic trap (do this a decent distance away, but not at the edge of the map) and stand on it.
- When you see the monster raise its tentacle, dodge out of the way (left or right on the analog stick +
) and attack the orange spot that sticks out clearly. - Rinse and repeat for all of the tentacles that have weak spots.
- Follow the QTE button prompts when they’re shown (
to mount, mash 
to attack, and press to dismount). - Take cover behind the piece of debris and wait for an opening right after the boulder lands.
- Run up the structure on the left to the top, dodging the tentacles along the way and watch the cutscene, follow any QTE prompt if you see any).
The achievement will unlock after its defeat.
