Adding a warning to drills' descriptions.

[Archtog]

There is no warning that when adding a socket to an item that it removes the current substats. Adding a warning would prevent new players from falling into this quite annoying trap and losing their item's substats.

You don’t necessarily lose the substat, at least, not forever. The substats will still be saved, so if you ever decide to remove the gem, those substats will return. 

But I understand where you’re coming from.
