Gnomish Mind Control Cap

The Gnomish Mind Control Cap can allow an engineer to Mind Control an enemy. When triggered, it turns target humanoid or player into a combat pet. This pet will fight on your behalf for 20 seconds, or until dispelled. As a combat pet, you get the standard pet control bars with which to control it.

There are a few limitations on this item. If, as a hunter or warlock, you already have a pet summoned, you will get the message "you already have a creature summoned." It also cannot be used if the target is in combat, thus requiring that it be triggered before combat.

The cap may be used by engineers with a skill of 215 or higher. Gnome Engineering specialization is apparently not required to use this item.

Possible malfunctions

 * Fails with no effect, but cooldown is trigged.
 * User becomes mind controlled by target. However, if the Gnomish Mind Control Cap is used while in a shapeshift form (such as cat form), this effect does not trigger.
