It's the poison that kills me... really?
Equipped with the rings I bought from the cat, I return to the misty lion man ruin and manage to talk to the previously silent man scorpion who introduces himself as Tark, possibly once known as Tarkus until something bad happened to him in Anor Londo. Apparently he wants me to help him slay his female counterpart who I had previously run into. Lucky for me he comes along to assist and on our second attempt (I misjudged the aggro swapping on the first one) we manage to slay her. Tark is satisfied and returns to his domain while I push on to a strange cavern full of locked doors which I quickly run out of keys for.
The place is guarded by slow moving elephant knights and ... really big dwarves(?) who are easy enough to run past. Eventually I emerge at a deep valley and after fighting through a small army camp I make my way down some dark, spider infested caves into a church where I have to slay a whole bunch of hollows and their magic wielding priest.
Oh, hell no.
Lower down is the continuation of the town, and it is absolutely infested with the poisonous arachnids (and some man-spiders), to the point that they start coming in swarms. Good thing the bastard sword has a wide sweeping arc attack which is effective at small group extermination. The lowest building seems to be where they are coming from, and I soon find out why: it's their lair.
