Me again

On the second run through the game and found 3 notes on the testament level I don't understand.
Note 1: Hit the targets if you want to see the eighth? (8th what and targets where?)
Note 2: If you want to be rewarded do not leave the madness (what madness where?)
Note 3: There are no clues for this one. A true mage an handle it himself (this ones near the head in the treasure room by some gates, still stuck with this one but have 4 one use magic scrolls but where do you use them?)
All the notes are near the end of the testament level and can't be gotten until you've done nearly the whole level and can't go back to other sections on this level.
I was considering taking screenshots of all the level maps when I've completed it again but I think some help would be needed to show every location and treasure if anyone's interested in helping out
