Ah, another wretched day in Tarren Mill. All of this clean air puts me in such a foul mood, <name>.
The sooner we can plague the humans here, the better. I've been conducting intense studies on possible killing agents to use in my concoctions but I haven't the time to collect them all.
If you want to make yourself of use, procure the following items for me: 10 Gray Bear Tongues and the very rare and hard to find, Creeper Ichor. You'll find both bears and creepers just outside of Tarren Mill.
