The Lost Dungeons of Norrath introduces an exciting new type of treasure to
EverQuest. Using new modular items gained from dungeon adventures,
characters are able to modify the powers and effects of their equipment,
allowing for a tremendous amount of customization.

Using these new items, characters can augment an existing breastplate, for
example. Bonding the proper augmentation item to the breastplate might give
it +5 strength. Bonding a different augmentation item could give it +6
wisdom. These are just a few simple examples; the new items have a wide
variety of possible effects and benefits.

Have a helmet that you like, but think needs a little boost? This new item
system allows you to customize that helmet and make it fit your character's
needs better. Most characters have a favorite item that they've had in their
bank for a while. They don't want to destroy it because it holds some
memories, a link to the adventures they had gaining it. With this new item
augmentation system, those items gain new life and endless potential!

I think this will be pretty cool. I have some items that I like that I would
love to augment. I guess it means the new items you find will allow you to
augment current armor. Someone likened it to the way gems affect items in
Diablo II. At the live chat they said that the augmentations can be undone
but that then they would be lost or something. And they said certain types
of armor can only take certain types of mods. Any comments or thoughts?
