If you don't add extra enhancements on it...ie...keep it to the weight reduction and +1....when the time comes you can just place +2 onto it without removing the the +1 first.

If an item has 3 enhancements, then one has to be removed before an upgrade can be done.

You are given a choice of which properties you wish to remove, so you just pick the one you want to remove, the rest will stay on the shield.

A tip....please make sure you read all the forge tells you...it could stop you making something you won't be able to use until a few levels later.

It should also let you know if you are going to lose a level enchanting the item so you can wait if you don't wish to lose the level.
