Bugged Achievement, I’ve tried do to this like 100 Times with Devil’s Puffball (Poison Bombs) but they won’t work with that Achievement. For me it finaly unlocked with the Viper-School Gear for that.
- You should be about Level 17 and used most Places of Power (or be a higher Level), so you can unlock the Crippling Strike Skill in the Combat Skill tree and equip it.
- You need 1000 Gold to buy the Potion of Clearance to reset you Skill points – if you are not 100% in the Combat Skill tree
- Build the Serpentine Steel Sword and may get a Greater Moranda Runestone to increase the chance to poison – the
- it helps if you have Tawny Owl to speed up Stamina regeneration
Now hit non-monster Enemies (you can use the Serpentine Silver Sword for Monsters, but is has a lower Poison chance, also a few Monstertypes are immune to poison ), they should bleed everytime you hit – thanks to the Crippling Strike Skill and use Igni to ignite them. A good place to do this is Aribjorn and Sund in Skiellige: there are a few wolf and they respawn if you Fast Travel.
