Gnomish Cloaking Device

This is an inexpensive trinket from a vendor-bought pattern found at Ravenholdt Manner in the Hillsbrad Foothills.

Use makes you invisible for 10 seconds to anyone (and most mobs) without the Detect Invisiblity buff from Warlocks.

1 hour cooldown.

According to the comments on the actual item, this trinket does not remove aggro. Anything you've already aggroed will still chase you, and enemies that have you targeted will still supposedly be able to target you. I posted this earlier, and since posting it acquired a cloaking device of my own; while being attacked by some Horde guards, I used the trinket and was promptly slashed to death as if I hadn't disappeared at all. In fact, the invisibility faded as soon as I was hit.

And this trinket lads is how I ran through the entire wintergrasp courtyard unnoticed.
Other cool tricks with this trinket include
-mixing it with the parachute cloak for a covert stealth jump.
-pally bubble then use this to escape, not that a pally ever needs to run =P.
-confuse the crap out of people when a non-stealth class all of a sudden vanishes.
-Heal yourself while Invisible
-As a rogue use this to get through aoe damage as it does not break invisibility
-use this to get through the dreaded wintergrasp earthbind totem field
