I'm not really sure what I did to unlock this. I had the festival mask and festival doll equipped. (My other equipment seems unlikely to be significant, but for the record it was a mushroom spade, bullet-holed vest, ReflexCoil pants, and lens focused on the distance.) I was adventuring in the Mushroom Cavern with a whole bunch of Fae Sight (125 duration) and Fae Blessing (714 duration). I fought a Twisted Hound and here's what happened:
You fire a heavy round into the hound for 18 ranged damage.
The hound rakes you with its claws for 1 melee damage, but the shock knocks the hound back, preventing all of the damage.You shoot the hound for 8 ranged damage as though it owes you something.
You've won the battle!
The hound collapses into a pile of dust in moments.
You found: hound dust
Hmph. If they're going to interrupt your party, they might as well at least make it a challenge.
