At least on the server where I was playing and got
banned there was an exploit with Jewelcrafter's gems. They are gems that are
-much- better than normal gems (normal gem could give 20 stam, it gives 41).
They are any color, but you should only be able to put 3 of them in your gear.
This is what the exploit is. In private servers it seems you can put as many
as you want, and get loads more spelldmg/ap/stam/what you want.
If your items have 5 sockets you get about 2000 more health.
Sorry if its a repost, searched "jewelcrafting"
Ok, since some people dont understand what, lvl your Jewelcrafting to 350 and put as many of these as you want
