Man, I love and hate this game. Same as Demon's Souls.
My story:
Finally beat that Capra Demon. I always seem to beat bosses after waiting a day or so and coming back. Anyway, made it to the Depths, fell down
every single goddamn hole because I wasn't paying attention. Fell into a pile of Basilisks, and managed to survive fighting all of them, and didn't even get cursed. It was awesome.
Then I got invaded, and he had some armor with enough Poise where striking him with my Scimitar didn't even faze him. Regardless, I whittled him down and took him out. up to 10k souls, which is about 5k more than I've ever had. I haven't found the bonfire down here yet since I fell down all the holes.
I contemplate using a Homeward Bone, but I didn't know about the bonfire, so I figured one had to be coming up soon. I look down and shit I'm out of Estus Flasks, and I have about 20% health left. I make my way past a bunch of rats to a pool with some weird slime things in it (remember, I fell down the holes so I hadn't encountered these yet).
Eventually tossed a firebomb at it and learned that fire's its weakness. Sweet. I can make it. I lure the two rats on the side of the pool towards me and take it out. All that's left...one more slime in the middle of the pool...
I run towards it, firebomb at the ready.
And then I thro...
what the fuck just fell from the ceiling and killed me? NOOOOO!
I eventually make it back to the Depths, and decide to find the bonfire. Along the way I get cursed and die, since I had no idea that the Basilisks can curse me. Son of a bitch.
Regardless, I made it to the boss, and I got the tail weapon, just need to finish him off next time.
