One thing I love about content patches is someone creative at Blizzard always sneaks in a few fun toys. Here%26#39;s two I%26#39;ve been enjoying using.
Jewelcrafted focusing lenses like the Shadow Jade Focusing Lens. When you use one you channel a spell that draws a beam%26#0160; of light between you and your target. Has a fairly long range, about 60 yards. They look cool, but they%26#39;re actually useful too. See, the beam ignores line of sight. Ever had something targeted and you couldn%26#39;t find where it was, like an NPC in the godawful town of Booty Bay? Just /target them and use the lens and now you have a beam pointing the way. I also imagine it%26#39;ll be useful in PvP to point out targets. The only drawback is you can%26#39;t move while channelling the beam.
The Toy Train Set from the toy vendor in Dalaran. Best 250g I ever spent. You put it on the floor and everyone within 5 yards starts doing the /train emote. Whether they want to or not. It%26#39;s like the Piccolo, only noisier and more irritating. It%26#39;s tempting to use this on a tight pack of people, say at the Naxxramas summoning stone. But that%26#39;s unsubtle and awfully obnoxious. I%26#39;ve enjoyed placing it in unexpected places, like the spot where you arrive right when you zone into an instance or where you land from a flight master. Putting it under a repair bot was pretty funny, too. Definitely needs to be used sparingly: I fear my guild might boot me entirely if I drop it in a raid again. (Guys, I love ya, I only used it last night to break the tension after our fifth wipe. Promise.)
