I was lving my alt in ruins of silvermoon today and an item dropped of the arcane patrolers Cracked Power Core - Item - World of Warcraft. it increase spell power by 15 for 30 seconds which is good for a 19 twink. its only for 30 seconds so i would recommend lving a bloodelf to 15 or whatnot to down the mobs easier and farm the power cores more efficiently w/o risk of dying because they're unique. I would station my alt at the inn in the area where u farm. All you do is log on lv 15 farm a power core. Mail it to twink and once u pick the power core up and go bg. I'm flagged as a leacher so i want to get out of here so i can post my scam. If you don't like it don't complain. its only 30 seconds and unique, if u were smart u would use it when the opposing fc is about to score or something that will affect the outcome of the bg in a bad way.
[Edit] I found out there's a similar item http://www.wowhead.com/?item=23381#dropped-by which would be better they drop of higher lv mobs though
