Slimes
Talk to the guy to hear some more about the plot and go
right. Take all the goodies and enter the house here and talk to
the man. He'll give you a sword, which will make fighting the slimes a
lot easier. Go right and save if you want to. Down are some
more goodies, get them, come back and go down the stairs. (Why stairs
in the ground, I've always wondered?) Even more goodies in this
cave, pick 'em up and head down-right. You'll see a huge slime
here, kill it (shouldn't be too hard) and go back out. Right
again and talk to the knight if you want more plot info. Then
down again and save if you want to. Down the stairs, pick up all
the goodies in this cave again and head down. There should be a
save machine here, last chance to save if you want to, so do so.
The boss shouldn't be too hard, but he does hit quite hard.
