You can get "spirit essence" by killing ghouls. If you don't want to venture into a graveyard, (reason enough not to with the GR there) you can go to the small valley near the AW lair at Ils Compassion and kill them.

Mmmm... OK, with everyones help I have completed the "Hag" quest.... Thank you all...

and I have had success with getting a Plaque beast core...

So, I now have my:
1- plaque beast core
1- Moonfire brew
1- piece of Obsidian

and I have ventured to the very spot deep in the solem hive... the spot that started it all... I am at the water purifier.... I read the book again to make sure that these are in fact the ingredients needed and YES, they are.... my heart starts to pound as I make sure all ingredients are in my main pack... my hand is shaking as I click the Apperatuse.... It makes a loud crash and a puff of smoke emminates as the handle turns and it make terrible rumbling noises.... It fills with water and says its purified now and dumps the water into the lake...

and then I wait... and wait... and wait.... hehe... Wow, this thing realy has NO purpose at all or maybe at one time it did.... and now its worthless.... I had fun today, I guess thats what counts right... hehe...

Thats too bad because we gardeners could have used Purified water for growing if you Dev guys bothered to set it up... It seems like all the programing is done, you just need to turn it ON... Let us fill a barrel full of water for 20 pitchers of Good water... Let it double the effects of Fertile dirt on our plants...

PS: does anyone know of any other uses for these ingredients? Thanks again.....

If you get more obsidian you can make a statue out of it.

My fave is my 'Statue of an Idiotic Madman'

This is true, 10 pieces of Obsidian will assemble into one of 50 unique statues, including (it is rumored) a statue of the player character that assembles the statue, so I suppose "A Statue of PwnZor RoXXorS" is possible, if rather distasteful. :grin:

I believe one of the statues is of "Goodman", a player who is no longer with us.

Yeah, that "Old Apparatus" doesnt do anything anymore...

I think that when you get the "Giant Black Widow" in the picture part of the Collectors Quest, any spider will do...could be wrong though.

For the nest time you go through either quest look here:

Collectors Quest

Hags Quest

On a side note, you also get either Sacrifice or Compassion points from teh Hags Quest as well...

Hag quest is good for treasure maps too.... thats how I got a good portion of mine back when I was an active "legacy" player. 90ish months now...

legacy... pfffff

Seasoned is a better term...
