i have a idea antimet

Yesterday I was thinking and me ocurred something, an article so called antimet that does the opposite to a met that you lowers of lvl the articles instead of raising them. His intention serious that if there is very high weapon the falls to your lvl or if it is that you passed of lvl and you want to lower, only want to know if serious possible this and that think of this.

It is possible, though it's has nothing to do with the item, hell, you can get an npc to do it for 5 gold, or free.

Just do it like Upgrade only in reverse :P

Yes, as Dominik said, re-write the Metupgrade NPC. Wont be hard.
As for adding the item, just use one of the released guides.
