Rare mobs fixes

A rare mob or monster is on a different timer than normal mobs in the area or sometimes only spawns X out of every Y instances you enter. Like elite mobs, rare mobs have a dragon around their portrait; however, unlike elites, this dragon icon is silver and lacks a wing on the side. They can also be elite (aka Rare Elite), in which case the wing is present. Rare mobs also have a unique name that distinguishes them from normal mobs, and unlike elite mobs (unless they are elite too), no "Rare" will appear after their name in the tooltip.
Here is a new video about how rare mobs are scripted on Nostalrius Begins.
