There really isn't a whole lot there besides a Dark magic spell (Dark Bead) and a new pyromancy spell (Black flame). However have you done Sif yet? If not when you walk across that bridge (where you can see all the humanity sprites milling around on one side) instead of heading down into the pit, head left.
Erm, I stumbled into Manus's lair last night. And the 'humanity' - O_o
Pointers in terms of what's there - I ended up looking at a few things, wood carvings, dark magic, Gough. But there's just the few areas Wood, Sanctuary, Township, Abyss, correct ? I think I somehow imagined there'd be a bit more. Had a couple of helpful summons guiding me, so that helped.
From there you should see a very familiar feline, follow her as she teleports, she leads you to a secret.
It is a brutal boss killer of a build, one of those builds that is difficult prior to all the parts coming together but once it does you can R2 spam your way through the rest of the game on bosses (except the last one).
Yeah I'm loving this build, the low VIT (20) is risky as it is possible to be one shottet (rarely but possible) but the power is immense.
With PW and CMW combined with a huge amount of endurance you can do ridiculous damage before your stamina runs out.
