Talk:Double Mastery Boost/@comment-221.185.84.96-20100929124748

My friend shared the item with 3 ramdomly selected memebers including me. I clicked "accept" to get a 2x boost. I didn't check whether I really received it under my inventory. When I did one of the highest energy costing jobs, I didn't get double mastery at all... I guess this boost is only available for a signle recipient only who claims the boost first.
