witcher 3 overkill achievement isnt working

You can begin making progress on this achievement by speaking with the Ofieri Merchant located at the Upper Mill fast travel point in eastern Novigrad. The solution is copied over from my xba guide.

You should only need to refill twice if you are chaining the effects correctly.This achievement is finally available after Patch 1.11 has been installed. You should have a indication of what number you are at by the amount of times you refill your bombs. Once you recover from the knockout, repeat. If you die from poison from the Devil's Puffball, you get throw to the loading screen. However, you must be killed by the guards for this to work.

You are simply knocked out and you get back up after a few moments. The best part about this location is that if the guards 'kill' you, you don't die but you lose money (Hooray for save points). Due to the high level of the guards, you may just be able to do one guard before you die. Do the following in order: use Devil's Puffball, shoot the Broadhead Bolt, use Igni/Dancing Star.

Once they begin to engage, lock onto one of them. Simply pull out your sword and do a few slashes to provoke them. There are usually two guards standing at the end of the bridge near the signpost. It is directly to the left on the signpost labeled Novigrad Gate. Location - I recommend the bridge outside of Oxenfurt. You can use regular Igni for this as well but its burning effect rate is fairly low so keep that in mind if going down that path. If you aren't a high enough level to get these abilities then use the Dancing Star Bomb instead. This will allow you to use Adrenaline Points for Signs and have an Adrenaline Point at the beginning of combat. Also get the Abilities Rage Management (General Branch) and Razor Focus (Combat Branch/Battle Trance Tree). Acquire Level 5 of the Ability Pyromaniac (last Ability of the Igni Sign) which gives 100% Burning effect to all Igni cast. Burning - Use a potion of clearance to free up your ability points. I recommend the Enhanced or Superior versions since the effect lasts for 30 sec but the Regular (10 sec) version work as well. Poisoning - Obtain and craft the Devil's Puffball. They apply the bleeding effect on hit for 15 sec. Bleeding - Buy Broadhead Bolts from the Blacksmith in Oxenfurt. Before anything else, make a save point you can load back to. There are multiple ways of applying the three effects.
