So for the three of you that want to or tried to do this in Velen / Novigrad. Probably a fairly pointless solution since the real solution will always just be 'Skellige', but ever in the name of science, I'm posting this anyways. The Axii sign can be used to turn an enemy into an Ally for a brief period of time once youve unlocked the second row of abilities for the magic spells (The skill is called Puppet). It's entirely possible these also count, however I did that mission at level 20-something, before Hearts of Stone felt feasible - so I didn't test as to whether you need those. An optional objective tasks you with destroying Arachas eggs - after examining the first one you come across, all twelve get marked with a Monster Nest logo. There's also another caveat to potentially consider - there's 12 unmarked 'monster nests' during the 'Contract: Missing Brother' Witcher contract. A sure shot way to get this trophy / achievement is to use Broadhead Bolts (bleeding), Devil 's Puffball Bombs (poisoning) and Dancing Star Bombs (burning).

I've seen no word on whether Beauclair would count as a possible region despite the unchanged achievement description, but I'd assume not. Overkill (Silver): This trophy is earned by bleeding, poisoning and burning an enemy simultaneously for a total of 10 times. I can confirm that at minimum, the Hearts of Stone Monster Nests are required (assumingly though, only if you've purchased the DLC) raising the required amount for that region to 29. Second time playing the game, so I decided to do this in the Velen / Novigrad region this time around just to see it done. This is a list of all obtainable achievements for The Witcher 3: Wild Hunt.
