Want to share some well-duh moments during my game last night:
I was mucking around in Velen, chasing chicken and shit when I stumbled upon a cave, it was dark so I used Cat (I prefer Cat to torch because it makes me feel safer knowing that the enemies can't quite see me as well as I see them with Cat), spotted a tons of Ghouls inside eating some corpses. So being a good witcher that I am, I slightly backed out, applied my enhanced necrophage oil on my silver blade, equipped my enhanced grapeshot, knocked down a Swallow potion too because I just fell from above and got severely hurt.
So the moment to attack came, just before I plunged into the crowd I apply Quen, then quickly switched to Igni, aimed my bomb and released.
The bomb fucking decimated all the ghouls, blew them to bits, all of them. I was left quite stunned because how easy it turnt out.
Apparently that cave tied to a quest, which I seriously overlevel.
End.
