The Guardians of Corp'rethar

These mobs have been altered some from beta > live, so here's an update. This quest is given as a followup to Before the Gate of Horror. The quest Shatter the Shards becomes available at the same time at this quest and should be done concurrently.

Both types of mobs can be found on the upper levels of Corp'rethar. They both have 88k hitpoints and can be snared/stunned. With a little patience ranged classes should be fine soloing these mobs. Melee types will probably want to find a tank or healer.

The Corp'rethar Guardians look like mini-Gluth's, they're melee-only mobs with no special abilities. They hit hard (around 5k on cloth) and apply a disease that has a Nature damage DoT and increases physical damage taken. Harbingers of Horror are pretty standard Liches (Frost Armor, casts Frostbolt and Fear). They also melee for about 5k on cloth and Frostbolt for around 4.5k. With a few slows, stuns, and interrupts these guys are a pushover, but use caution.

The Icecrown is done! Leave your comments/sugestions at my comment in Icecrown zone. Thanks everyone who helped me to make it via comments on wowhead and in-game pre-quest tracking.

As an additional point regarding the Harbingers of Horror (lich mob) they do have a knockback with some pretty serious distance. Make sure you are aimed correctly, lest you go flying off.
