I happen to have the exact opposite problem as the original poster.
As far as I can tell, I have found and completed everything I can on Claymore.
However, I seem to only know where two white flowers are, one head, and have no idea where the broken computer is. It doesn't help that Hoffmann is about as brightly lit as Schrödinger's box prior to it being opened.
Help? (Honestly the 'light' issue isn't so much an issue with the game as it is my monitor. I generally have to ramp up the gamma on most modern games.
)
EDIT: To answer my own question...
The pool is a useful thing. In fact, some of the techniques you picked up on Claymore could be used to use the pool in a more useful position.
EDIT2: However, there's still one thing I don't know the answer to, even though I seem to have completed this system...
What's with the blue 3x3 block of text?
