THE WITCHER 3: WILD HUNT

Easiest way is by using the bow with the Broadhead Bolts (100% bleeding) + Puffball bomb (poison) + Dancing Star bomb (fire) at the Devil's Pit location.

Don't forget to meditate to replenish your bomb and fast travel to have the bandit respawn. Do this and you'll get the achievement in less than 10 minutes.

Thanks

New Solution:

Since a previous update, they patched in being able to use equipment now, which makes this achievement A LOT easier.

Get some Broadhead Bolts for bleeding, Puffball bomb for poison and Dancing Star bomb for fire and head over to the Devil's Pit located next to the Hanged Man's Tree.


Old Solution:

Before I got the achievement I put PS4Tophies guide here, but I'm going to edit and add how I did it personally, so there will be two guides here, use which ever you want.

To get the effects at the same time, I recommend doing this:

For Bleeding: Under Combat skills; the very last fast attack one (Crippling Strikes; Use a Potion of Clearance if you have to) causes bleeding damage for each fast attack. As for as I know, it's 100% chance of bleeding.

For Poison: Make the Serpentine Steel Sword. That gives 15% chance to poison (+5 more if you equip a greater poison stone).

For Fire: Just use Igni.


My Guide:

What I did to get the achievement was I made the Serpentine Steel Sword and used it on monsters. The reason I did this was because steel swords are way weaker against monsters so it gave me more hits which helped guarantee all 3 effects at the same time. I also recommend taking off your red mutagens so you'll do even less damage. It helps a lot.

Tip: Un-equip your Silver Sword so you don't constantly keep switching to it mid-combat.

South/South East of Devil's Pit (next to Hanged Man's Tree) is a place where nekkars spawn. Attack the nekkars with the steel Serpentine Sword and wait until you see "bleeding" and "poisoning" pop up (for me it did around 70-80 red damage), then use Igni and hope they light on fire. This literally took me 15 mins to get and I expected it to take longer than that.

PS4Trophies Guide:

PS4Trophies made a video guide on how to do it by killing wolves. For those not interested in watching the video, I'll write a written guide.

In the video he goes here:


Which is in Skellige and has a pack of level 15 wolves. He just hacks away with the sword and when the effects pop up, he uses Igni to (hopefully) cause burning, After all wolves are dead, leave the area and then go back and do it again until you get the achievement.

I am only posting this solution as the solutions above did not help me at all but only due to the fact of my level.
If you're trying for this achievement at an earlier level, by all means follow the guides posted prior to this one as they will be better. This guide simply proved easiest for this achievement from level 35.

If you are struggling to get this achievement from a high level on weaker enemies, you wan't to do a few things.

- Build the Serpent Steel Sword that gives 15% chance to poison.(Add extra % from skill upgrade and runestone)

- Make sure in your Fast Attack skill tree you have upgraded the last ability in this section that basically allows every Fast Attack to cause bleeding.

- Make sure that once the weapon is built, unequip your silver sword and make sure that the Serpent Steel Sword is the only weapon equipped.(We will be using this weak steel sword on Monsters as it will do less damage)

- Make your way back to Kaer Morhen, you can fast travel to the Lakeside Hut.(Providing as a high level, you have got this far in the story and regained access to thie area.)

- Head your way North up the east coast and you will find a bunch(4-6)level 12 bears that can sustain a fair bit of damage and don't do much in return. Just attack them til you see Bleeding/Poisoning appear above their head then finish them off with Igni.

Repeat this process as many times as it takes til the achievement pops. If the bears have all died, fast travel out of the area(To another City)and come back to allow the bears to respawn.

A few steps from this guide are similar to the guides posted prior to this one, this guide is simply an update of how to get this achievement from a high level. Good luck!

Go to The Devil's Pit because Humans are not immune to any of the status effects, they also respawn here when you leave the map.

Use bolts for bleeding, Devil's Puffball for poison and Igni to burn. Freeze them first with Axii to make it easier!

See my video below for help!

I know there is a few solutions already up but I thought I'd share my solution since it's quite the easy one and is also a good way to level up. Just down of YUSTIANNA'S GROTTO in Skellige, there is a cyclop that can respawn every five seconds. You just need to meditate and He'll just spawn back. (Refer to my screenshot for the location)



Note that the cyclop is level 21 but won't be a problem even if you'd be 5 levels below. The strategy is use AXII come close slash him with fast attack so Crippling Strikes Proc. If you don't have Cripple Strikes, use the Feline Silver Sword (it grants you 10% Chance to cause bleeding) make sure to enchant your weapon with Greater Morana runestone which will give you 5% Chance to poison. I'd recommend using Feline Silver Sword even though Viper Silver Sword gives you more chance to proc poison. I'd also suggest that you put 5/5 into Poisoned Blades with the extra 15% chance of poisoning the target on each hit when you use any oil. Back to the topic, once the target is mind-controlled just spam till you see the DOT (damage over time) over his head in red numbers for me it was around 233 every seconds then you switch to IGNI and burn him.

It sounds complicated but once you get the rotation running it's quite simple and you gain around 23 per kill as experience. I gained almost two levels by doing this achievement.
