In the past I've sometimes popped eq and given it away or sold it to the shop thinking that I didn't need it, only to find it's an important forge cp later.
You can't easily search inside all the forge lists on the eq list to see if a component is used in a forge... so... last night, with a little bit of help from 'wget' I used a script to download all the information in the popup html windows about forges and all there components.
I was specifically looking for "Conch Shell" which id's as a cp, only to find it's not in any of the forge lists I downloaded.
I know there are some cp's in the game not used in any forges... but on the other hand I've heard rumours of forges that no one knows about yet.
I'm wondering if any one knows about the conch shell, and maybe if there is a forge in underdark somewhere we haven't found. The couch shell has +2 ma regen, and if it id's as a cp, and it is infact in a forge, it could quite possibly be a nice item.
