The cow exploit used to allow you to kill cows, loot, meditate, kill other cows and loot again, so you could go to a merchant and sell everything you looted for a conspicuous amount of crowns. Of course, CD Projekt RED has worked to fix that exploit and gave a solution in the patch 1.05 released yesterday.
As you can see from this video, you can still kill cows but, if you meditate in the same place where you killed those cows, a level 27 chort appears. The only thing you can do, unless you being a level 30 or so witcher, is to escape.
Anyway, there still someone who is killing cows, meditating, and killing the chorts. Take a look at this pic, which could just lead to another, high level monster-based exploit:
Someone’s even practicing with the monster, making the exploit on purpose to just face this huge challenge. On Reddit, a gamer says the monster slayed him with just one hit; another, instead, killed it after a 10 minute fight.
What’s your take on this? Did you appreciate CD Projekt RED’s reaction to the exploit discovered by gamers?
