Question about Zariche Sword

Where can I find some information, what does this sword give?
Yesterday when I was in the game I sow that this sword was dropped in Cemetery (do not remember exactly)...
I've heard it increases your power, but how?
Some percentage or fixed? Is there any information?
And why does it disappear?

Please see this page (http://www.lineage2.com/Knowledge/cp.html) for more information about Zariche. :)

Cause you can practically solo raid bosses with it, thus powerlvl up yourself very easily(if you manage to keep it).
Thats why it disappears :)

Wow! So even that now I'm now level 5, I can get this sword!!! Cooool! But how strong would I be? I mean how much it will change my stats? Will my HP increase, or CP? Any information on that?

game mechanics mean you will have that sword about 5 minuets before somone takes it off you :/

I wonder how much my stats would change :)

Patk on my SWS went from around 650ish to 12000, everyone hunts you though, luckily I was at a decent enough level to maim them all :>

Soloing a raid boss took me around 40mins.. only worth it for the drops.

there was actually i think a lvl 4 guy who managed to get the zariche
not impressive by high lvl standards but the difference to you is amazing

if you do manage to get the thing as a lowbie what you want to do is instantly log out
make an alt and head to where you logged out and tell the ppl waiting there to kill you that you will not log that toon back in unless they give you X million adena

trust me its worth it for a high lvl player to throw you a few mil to get their hands on the thing and if you dont log back in the sword will be unavaliable for i think about a week
