Where does one obtain more of those Black Bombs? They were rather useful in the beginning. I haven't found any suppliers for them yet…

I've just finished up as much of the Darkroot Garden area as I could after killing the um…boss that's there.

I thought those Lloyd's Talisman's might be what I needed to make exploration of the Catacombs easier, but alas, the skeletons keep coming back. I'm also at a loss for how to take on the dragon at the bridge short of running face on into a furnace. I haven't resorted to bows at all yet…
So I think I'm going to explore downwards from Firelink and see what I can find.
