The Witcher 3: Wild Hunt "David and Golyat" achievement

(First time uploading a video on here ^.^ "David and Golyat" hidden trophy Easiest way to get this is to use Northern Wind bomb (freezes enemy) and crossbow(mandatory for this trophy). **also putting your skill points where it increases your crossbow attack/accuracy will help!!) Shoot in the holes of the barrel (freezing Golyat greatly helps accuracy) (I couldn't figure out how to edit the video where the trophy pops up but if you do it right, the trophy will pop up as soon as he falls to the ground. (Save before cutscene in Velen before heading to Toussaint just in case you miss it and want to retry it) The Witcher 3: Wild Hunt https://store.playstation.com/#!/en-ca/tid=CUSA00527_00
