I don't suppose anyone knows any teachers for this skill? I've had an eye open for it for at least the last two acts (I just got spilled into Act 4 against my will tonight, so I'm playing it, because I honestly don't want to go back and do Act 3 *again*), both in-game and in the battlefield, and I can't find it. I've got a half-dozen solid gold dead useful charms in my inventory, too...
