Yesterday, I kept going back to this Nightmare Tombstone area I'm in, where you're constantly getting poisoned down in this poison stream, so I just use my old technique of lots of health potions instead of bothering with antidotes. I was making good progress until I got to this creature that made me frenzied and my head exploded.
And then I realized after I respawned: Oh crap, I'm out of health potions.
And I couldn't go back, because some lady is ringing her god damn bell somewhere. So after I died, I got a five second window of time before the lady rings her bell, so I was able to get back to the Hunter's Dream. Since I'd died, I had lost all my blood obviously. So I cashed in a lot of my blood thingies that I'd been collecting for a while. I cashed in the two lowest categories of blood I had. And with that, I was able to buy...... 7 blood vials.
Facepalm. That's not enough.
So yeah, I'll have to go back and get blood vials from somewhere so that I can go back to that poison river and confront that frenzying creature. How do you fight getting frenzied? Do you just have to beat that enemy fast? Can you slow down the frenzy meter with some kind of item?
