Dialogue

NPC

Guess I'll do it myself, you useless bucket of bones.

NPC

Collect Noxious Spores from purple mushrooms. They usually just fall out onto the ground. Stuff them in this container. Once you've got all the spores in there, shake it up really well... it'll make the ultimate poison! Then... HE WILL FINALLY DIE!

NPC

Are you serious? Ugh, whatever.

NPC

Of course you'd back out. Pathetic.

NPC

I'm going to poison the hell out of him!

NPC

Bet you can guess what it is from the items I had you collect...

NPC

So, meatbag, you're back. Ready for phase two of my master plan?

NPC

Poisonous mushroom spores? You insult me. All this is, is a decent laxative. Pathetic...
