This achievement is not as easy as it appears. In order to get a good start on stacking the buff, you'll need to kill three - if not four - of the electrocutioners at the same time. (Alayea and I found this out the hard way, as the buff kept dropping off before we could kill the next mob.)

VERY IMPORTANT: You must be in melee range in order to receive the Power Surge buff. Casters, this means you!

In the area that Metal Lord Mono-Han patrols are several electrocutioners busy electrifying... piles of stone. Don't be afraid to grab one of them to refresh the Power Surge buff during your fight with Mono-Han when he is spinning in place or otherwise not doing a special ability (which simply comes down to not standing in Bad Stuff).

It is so easy to keep the ten-stack that Alayea and I stuck to that area and farmed for Black Prince reputation.* Power Surge = Pew Pew!

*Your Mileage May Vary. At this point in time we had no competition at all for mobs because... there's a way in without having unlocked the area. No, I won't say how. Oh, and don't think you can get the Thunder-forge recipes early - Blizzard hotfixed Itoka so that he'll spawn only once the area is truly unlocked, I believe.

We also had the rep buff from the Darkmoon Faire Carousel, which helped a lot. And yeah, Itoka got hot-fixed out of the game until the stage area actually is unlocked (but not before some lucky blacksmiths got their loot).

Edit: Heard through various sources that at least one player that obtained the IoT blacksmith recipes got a 72-hr suspension and loss of the recipes. Ouch.
