im playing Lilith for the first time cuz i got bored form the original TQ[finished it 18 times] so i got lilith...anyway i found two "parchments of the beast" one form the over-sized Scorpos and the second from the boss in asteria west beach..whats the purpose of the parchments..and where can i find the other parts...
The purpose of the parchments is to unlock something later in the game. They are dropped from bosses, but quasi-rarely so you need to farm some many times before you can collect them all.
This stuff is detailed in many places including a wiki-dot site for Lilith created by Sketel and a French site called Lilithopedia. Search for them.
